Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives of property and equipment; valuation allowance for net deferred taxes; the cost and offsetting income related to sub-leased property; and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment.

We are in the process of evaluating the impact of the standard but do not expect any material financial statement impact upon adoption.</span></div></ix:nonNumeric><ix:nonNumeric contextRef="ibd502b42537249afbed7b2249d973f66_D20220101-20220630" name="us-gaap:RevenueRecognitionPolicyTextBlock" id="id3VybDovL2RvY3MudjEvZG9jOmE2MDZjNzU4MzhlYTQ5OGY5MGNiYjBhNmRjMzc1OWUyL3NlYzphNjA2Yzc1ODM4ZWE0OThmOTBjYmIwYTZkYzM3NTllMl80MC9mcmFnOmY0NWJiMzM5ZGI1MDQwNTQ5MjQxMzJjNDUwMDYwYzczL3RleHRyZWdpb246ZjQ1YmIzMzlkYjUwNDA1NDkyNDEzMmM0NTAwNjBjNzNfMTcxOTM_b47f37de-1a05-4fab-8065-1319227e5d11" continuedAt="if8d4766ad82747f4ae68dee641c77ace" escape="true"><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Revenue</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Net sales include revenues from sales of products and shipping and handling charges, net of estimates for product returns.

to and currently due from customers. Our customers are concentrated in the United States. In the normal course of business, we extend unsecured credit to our customers related to the sale of our products. Credit is extended to customers based on an evaluation of the customer&#8217;s financial condition and the amounts due are stated at their estimated net realizable value. We utilize a third-party account receivable insurance program with a very high credit worthy insurance company where we have the large majority of the accounts receivable insured with a portion of self-retention. This third party also provides credit-worthiness ratings and metrics that significantly assist us in evaluating the credit worthiness of both existing and new customers. We maintain allowances for sales returns and doubtful accounts receivable to provide for the estimated number of account receivables that will not be collected. The allowance is based on an assessment of customer creditworthiness and historical payment experience, the age of outstanding receivables, and performance guarantees to the extent applicable. Past due amounts are written off when our internal collection efforts have been unsuccessful, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. We do not generally require collateral from our customers.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our standard payment terms with customers are net 30 days from the date of shipment, and we do not generally offer extended payment terms to our customers, but exceptions are made in some cases for major customers or with particular orders.

Warranty settlement costs consist of actual amounts expensed for warranty, which are largely a result of the cost of replacement products provided to our customers. A liability for the estimated future costs under product warranties is maintained for products under warranty based on the actual claims incurred to date and the estimated nature, frequency, and costs of future claims. These estimates are inherently uncertain and changes to our historical or projected experience may cause material changes to our warranty reserves in the future. We continuously review the assumptions related to the adequacy of our warranty reserve, including product failure rates, and make adjustments to the existing warranty liability when there are changes to these estimates or the underlying replacement product costs, or the warranty period expires.</span></div></ix:nonNumeric><ix:nonNumeric

The Company had one finance lease containing a bargain purchase option that was not renewed upon expiration of the lease during the second quarter of 2022. The lease term consists of the non-cancellable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option.

We develop, market and sell high quality light-emitting diode (&#8220;LED&#8221;) lighting and controls products and UVCD products in the commercial market and military maritime market (&#8220;MMM&#8221;), and expanded our offerings into the consumer market beginning in the fourth quarter of 2021. Our mission is to enable our customers to run their facilities, offices, homes and vessels with greater energy efficiency, productivity, and human health and wellness through advanced LED retrofit and UVCD solutions. Our goal is to be the human wellness lighting and LED lighting technology and market leader for the most demanding applications where performance, quality, value, environmental impact and health are considered paramount. We specialize in LED lighting retrofit by replacing fluorescent, high-intensity discharge lighting and other types of lamps in institutional buildings for primarily indoor lighting applications with our innovative, high-quality commercial and military-grade tubular LED (&#8220;TLED&#8221;) products, as well as other LED and lighting control products for commercial and consumer applications. In late 2020, we announced the launch of our UVCD product portfolio.

The sales cycles for the MMM is dependent on many factors, including the availability and prioritization of government funding, the timing and fulfillment of U.S. Navy awards, new ship construction, diversion of funds to other government needs, and the timing of vessel maintenance schedules, and our financial results reflect volatility from fluctuations in the timing, pace and size of MMM projects. However, we reinvested in our MMM sales channel with a strategic hire in the second quarter of 2022 and continue to pursue these opportunities. In our commercial markets, while we are beginning to see an uptick in customer projects and purchase commitments, the sales cycles can range from several months to over one year and our financial results also reflect volatility from the continued fluctuations in the timing, pace and size of commercial projects due to, among other reasons, the long-term effects on our customers of the coronavirus (&#8220;COVID-19&#8221;) pandemic.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Operating losses increased by $0.3&#160;million, or 7%, in the first six months of 2022 from the first six months of 2021. The Company&#8217;s results reflect the challenges due to long and unpredictable sales cycles, delays in customer retrofit budgets and project starts, and supply chain issues, primarily related to shipping costs exacerbated by the continuing effects of the COVID-19 pandemic. We have been challenged by continuing and intensifying aggressive price competition in the lighting industry, particularly in our retrofit market, as well as increased logistics expenses that are weighing on margins. We continued to incur losses and we have a substantial accumulated deficit, which continues to raise substantial doubt about our ability to continue as a going concern at June&#160;30, 2022.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The COVID-19 pandemic in particular has, and may continue to have, a significant economic and business impact on us. We saw a slight improvement in commercial sales in the first half of 2022, following slowdowns in 2021 and 2020, as end customers in the healthcare, education, and commercial and industrial sectors delayed order placements in reaction to the impacts of the COVID-19 pandemic that caused our customers to suspend or postpone lighting retrofit projects due to budget and occupancy uncertainties. We remain cautious as our commercial sales reflect the volatility of large institutional end customers. Global supply chain and logistics challenges have further exacerbated slowdowns in customer projects, as well as impacted our margins, inventory and shipping strategies to respond to customer and supplier timelines.</span></div><div style="height:45pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">29</span></div></div></div><hr style="page-break-after:always"/><div style="min-height:45pt;width:100%"><div><span><br/></span></div></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We continue to monitor the impact of the COVID-19 pandemic on our customers, suppliers and logistics providers, and to evaluate governmental actions being taken in response to the pandemic.

Disruptions in global logistics networks are also impacting our lead times and ability to efficiently and cost-effectively transport products from our third-party suppliers to our facility. The significance and duration of the ongoing impact on us is still uncertain. Material adverse effects of the COVID-19 pandemic on market drivers, our customers, suppliers or logistics providers could significantly impact our operating results.

The EnFocus&#8482; platform offers two immediately available product lines: EnFocus&#8482; DM, which provides a dimmable lighting solution, and EnFocus&#8482; DCT, which provides both a dimmable and color tunable lighting solution. EnFocus&#8482; enables buildings to have dimmable, color tunable and circadian-ready lighting using existing wiring, without requiring additional data cables or any wireless communication systems, through a relatively simple upgrade with EnFocus&#8482; switches and LED lamps.

We continue to pursue opportunities from the U.S. Navy and the government sector to minimize such volatility, and reinvested in our MMM sales channel with a strategic hire in the second quarter of 2022. Previously in our MMM business, significant efforts undertaken to reduce costs in our product offerings have positioned us to be more competitive along with improved production efficiencies. Additionally, we are an approved supplier for the General Services Administration (&#8220;GSA&#8221;) and many of our products are now listed in the GSA website for all federal and military agencies to view and order our products, a channel we hope to further develop. While we continue to aggressively seek to increase sales of our commercial products, we are reinvesting in the MMM business as we believe it offers us continued sales opportunities, in addition to validating our product quality and strengthening our brand trust in the marketplace.

net sales of $2.1&#160;million, primarily driven by a decrease in MMM sales of $0.5&#160;million, or 49%, and a decrease of $0.1&#160;million, or 10%, of commercial products sales. Net MMM product sales decreased in the second quarter of 2022 compared to the same period in 2021, mainly due to availability and prioritization of government project funding and the delayed timing of expected orders. The decrease in commercial product sales in the second quarter of 2022 reflects (i) volatility of sales to large institutional customers; (ii) fluctuations in the timing and pace of commercial projects, including where lead times extended into the subsequent quarter; and (iii) lingering macroeconomic supply chain impacts as a result of the COVID-19 pandemic. </span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:112%">Net sales of $3.5&#160;million for the first six months of 2022 decreased $1.2&#160;million, or 25%, compared to the same period in 2021, primarily driven by a decrease in MMM product sales offset slightly by increased commercial sales. Net sales of our MMM products decreased mainly due to availability of government funding and the delayed timing of expected orders in the first six months of 2022.

These decreases were offset by a favorable net impact of $0.2 million, or 11% of net sales, from our inventory reduction project, with the change in inventory reserves offset by the inventory scrap write-off.

Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives of property and equipment; valuation allowance for net deferred taxes; the cost and offsetting income related to sub-leased property; and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment.

Our customers are concentrated in the United States. In the normal course of business, we extend unsecured credit to our customers related to the sale of our products. Credit is extended to customers based on an evaluation of the customer&#8217;s financial condition and the amounts due are stated at their estimated net realizable value. We utilize a third-party account receivable insurance program with a very high credit worthy insurance company where we have the large majority of the accounts receivable insured with a portion of self-retention. This third party also provides credit-worthiness ratings and metrics that significantly assist us in evaluating the credit worthiness of both existing and new customers. We maintain allowances for sales returns and doubtful accounts receivable to provide for the estimated number of account receivables that will not be collected. The allowance is based on an assessment of customer creditworthiness and historical payment experience, the age of outstanding receivables, and performance guarantees to the extent applicable. Past due amounts are written off when our internal collection efforts have been unsuccessful, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. We do not generally require collateral from our customers.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Our standard payment terms with customers are net 30 days from the date of shipment, and we do not generally offer extended payment terms to our customers, but exceptions are made in some cases for major customers or with particular orders.

Warranty settlement costs consist of actual amounts expensed for warranty, which are largely a result of the cost of replacement products provided to our customers. A liability for the estimated future costs under product warranties is maintained for products under warranty based on the actual claims incurred to date and the estimated nature, frequency, and costs of future claims. These estimates are inherently uncertain and changes to our historical or projected experience may cause material changes to our warranty reserves in the future. We continuously review the assumptions related to the adequacy of our warranty reserve, including product failure rates, and make adjustments to the existing warranty liability when there are changes to these estimates or the underlying replacement product costs, or the warranty period expires.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New

Also in April 2021, we expanded the borrowing capacity on one of our revolving credit facilities.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The restructuring and cost cutting initiatives taken throughout 2021 and continuing into 2022, as well as the June 2022 Private Placement, the December 2021 Private Placement and the June 2021 Equity Offering that strengthened our balance sheet, our credit facility capacity increase and bridge financings in April 2022 and April 2021, and the funds we expect to receive related to the Employee Retention Tax Credit (&#8220;ERTC&#8221;; see Note 11, &#8220;Other Income&#8221; for details), were all designed to allow us to effectively execute these strategies. However, our efforts may not occur as quickly as we envision or be successful due to the long sales cycle in our industry, the corresponding time and inventory management required to ramp up sales from new products, markets, and customers into this sales cycle, the timing of introductions of additional new products, significant competition, potential sales volatility given our customer concentration, numerous interruptions and cost increases in the supply chain globally, and the long-term economic impact from the COVID-19 pandemic that has significantly diminished the interest and activities for our customers&#8217; lighting retrofit projects until occupancy returns to more normal levels, among other factors.</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Additionally, global supply chain and logistics constraints are impacting our inventory purchasing strategy, as we seek to manage both shortages of available components and longer lead times in obtaining components while balancing the development and implementation of an inventory reduction plan. Disruptions in global logistics networks are also impacting our lead times and ability to efficiently and cost-effectively transport products from our third-party suppliers to our facility. As a result, we will continue to review and pursue selected external funding sources to ensure adequate financial resources to execute across the timelines required to achieve these objectives including, but not limited to, the following:</span></div><div style="padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">obtaining financing from traditional or non-traditional investment capital organizations or individuals; </span></div><div style="padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">obtaining funding from the sale of our common stock or other equity or debt instruments; and</span></div><div style="margin-bottom:10pt;padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">&#8226;</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt">obtaining debt financing with lending terms that more closely match our business model and capital needs.</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">There can be no assurance that we will obtain funding on acceptable terms, in a timely fashion, or at all.

If we fail to obtain the required additional financing to sustain our business before we are able to produce levels of revenue to meet our financial needs, we will need to delay, scale back or eliminate our growth plans and further reduce our operating costs and headcount, each of which would have a material adverse effect on our business, future prospects, and financial condition. A lack of additional funding could also result in our inability to continue as a going concern and force us to sell certain assets or discontinue or curtail our operations and, as a result, investors in the Company could lose their entire investment.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Considering both quantitative and qualitative information, we continue to believe that the combination of our plans to ensure adequate external funding, timely re-organizational actions, current financial position, liquid resources, obligations due or anticipated within the next year, development and implementation of an excess inventory reduction plan, plans and initiatives in our research and development, product development and sales and marketing, and development of potential channel partnerships, if adequately executed, will provide us with an ability to finance our operations through the next twelve months and will mitigate the substantial doubt about our ability to continue as a going concern.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">On August 17, 2020, we received a letter from the Listing Qualifications staff (the &#8220;Staff&#8221;) of The Nasdaq Stock Market (&#8220;Nasdaq&#8221;) notifying us that we were no longer in compliance with Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain stockholders&#8217; equity of at least $2,500,000 if they do not meet the alternative compliance standards relating to the market value of listed securities or net income from continuing operations (the &#8220;Minimum Stockholders&#8217; Equity Rule&#8221;). Our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2020, filed on August 13, 2020, reflected that our stockholders&#8217; equity as of June 30, 2020 was $1,714,000. Based on our timely submission of our plan to regain compliance, Nasdaq granted us an extension through February 15, 2021 to regain compliance with the Minimum Stockholders&#8217; Equity Rule. In accordance with one part of the plan submitted to the Staff, we successfully modified our outstanding January 2020 Warrants and in December 2020, we reclassified $1.4&#160;million from warrant liability into equity. On January 20, 2021, we received a letter from the Staff notifying us that, on a conditional basis, Nasdaq has determined that we have regained compliance with the Minimum Stockholders&#8217; Equity Rule. At December 31, 2020, our stockholders&#8217; equity was $4,255,000, satisfying the Minimum Stockholders&#8217; Equity Rule. At December&#160;31, 2021, our stockholders&#8217; equity was $6,209,000 and at June&#160;30, 2022, our stockholders&#8217; equity was $4,171,000.</span></div><span></span>

The Company had one finance lease containing a bargain purchase option that was not renewed upon expiration of the lease during the second quarter of 2022. The lease term consists of the non-cancellable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option. As of January 21, 2021, the terms of one of our equipment operating leases had been extended through 2026. Additionally, as of March 25, 2022, in connection with extending through 2027, the terms of our expiring headquarters real estate operating lease for manufacturing, warehouse and office space have been modified beginning July 1, 2022 to reflect a smaller footprint at reduced costs.

The present value of the lease obligations for these leases were calculated using an incremental borrowing rate of 15.93% for the equipment lease and 16.96% for the real estate lease, which were the Company&#8217;s blended borrowing rates (including interest, annual facility fees, collateral management fees, bank fees and other miscellaneous lender fees) on its revolving lines of credit with Crossroads Financial Group, LLC (as described below in Note 7, &#8220;Debt&#8221;) and Factors Southwest L.L.C. (as described below in Note 7, &#8220;Debt&#8221;). The present value of the other remaining lease obligations continues to be calculated using an incremental borrowing rate of 7.25% (which excludes the annual facility fee and other lender fees), which was the Company&#8217;s borrowing rate on its former revolving line of credit with Austin Financial Services, Inc. (the &#8220;Austin Credit Facility&#8221;).

The Company had one finance lease containing a bargain purchase option that was not renewed upon expiration of the lease during the second quarter of 2022. The lease term consists of the non-cancellable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option. As of January 21, 2021, the terms of one of our equipment operating leases had been extended through 2026. Additionally, as of March 25, 2022, in connection with extending through 2027, the terms of our expiring headquarters real estate operating lease for manufacturing, warehouse and office space have been modified beginning July 1, 2022 to reflect a smaller footprint at reduced costs.

The present value of the lease obligations for these leases were calculated using an incremental borrowing rate of 15.93% for the equipment lease and 16.96% for the real estate lease, which were the Company&#8217;s blended borrowing rates (including interest, annual facility fees, collateral management fees, bank fees and other miscellaneous lender fees) on its revolving lines of credit with Crossroads Financial Group, LLC (as described below in Note 7, &#8220;Debt&#8221;) and Factors Southwest L.L.C. (as described below in Note 7, &#8220;Debt&#8221;). The present value of the other remaining lease obligations continues to be calculated using an incremental borrowing rate of 7.25% (which excludes the annual facility fee and other lender fees), which was the Company&#8217;s borrowing rate on its former revolving line of credit with Austin Financial Services, Inc. (the &#8220;Austin Credit Facility&#8221;). The weighted average remaining lease term for the operating leases is 4.9 years.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company had one restructured lease with a sub-lease component for the New York, New York office that was closed in 2017.

The first arrangement is an inventory financing facility (the &#8220;Inventory Facility&#8221;) pursuant to the Loan and Security Agreement (the &#8220;Inventory Loan Agreement&#8221;) between the Company and Crossroads Financial Group, LLC, a North Carolina limited liability company (the &#8220;IF Lender&#8221;). Borrowings under the original Inventory Facility were permitted up to the lower of (i) $3.0 million, which amount was subsequently increased to $3.5 million as described below, and (ii) a borrowing base determined from time to time based on the value of the Company&#8217;s eligible inventory, valued at 75% of inventory costs or 85% of the inventory net orderly liquidation value, less the availability reserves. On April 20, 2021, the Company and the IF Lender entered into an amendment to the Inventory Loan Agreement to increase the maximum amount that may be available to the Company from $3.0 million to $3.5 million, subject to the borrowing base as set forth in the Inventory Loan Agreement. The outstanding indebtedness under the Inventory Facility accrues at an annual rate equal to the greater of (i) 5.75% and (ii) 4.00% plus the three-month LIBOR rate (2.29% and 0.21% at June&#160;30, 2022 and December&#160;31, 2021, respectively) and is also subject to a service fee of 1% per month. The annualized interest rate at June&#160;30, 2022 and December&#160;31, 2021, which includes interest fees, the annual facility fee, bank fees and other miscellaneous lender fees, was 22.1% and 22.4%, respectively. The Inventory Facility&#8217;s interest and service fees combined amount is subject to a minimum monthly fee of $18 thousand. There would be no breakage fee for the Company for the Inventory Facility if the Company were to refinance it with an American Bankers Association (&#8220;ABA&#8221;) equivalent institution. The Inventory Facility is secured by substantially all of the present and future assets of the Company and is also governed by an intercreditor agreement among the Company, the IF Lender and the RF Lender (defined below). The Inventory Facility matures on August 11, 2022, subject to early termination upon 90 days&#8217; notice and otherwise in accordance with the terms of the Inventory Loan Agreement. The term is automatically extended in successive one (1) year increments unless terminated by either party in accordance with the Inventory Loan Agreement.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The second arrangement is a receivables financing facility (the &#8220;Receivables Facility&#8221;) pursuant to the Loan and Security Agreement (the &#8220;Receivables Loan Agreement&#8221;) between the Company and Factors Southwest L.L.C. (d/b/a FSW Funding), an Arizona limited liability company (the &#8220;RF Lender&#8221;). Borrowings under the Receivables Facility are permitted up to the lower of (i) $2.5 million and (ii) a borrowing base determined from time to time based on the value of the Company&#8217;s eligible accounts receivable, valued at 90% of the face value of such accounts receivable, less availability reserves, if any. Interest on outstanding indebtedness under the Receivables Facility accrues at an annual rate equal to (i) the highest prime rate announced from time to time by the Wall Street Journal (4.75% at June&#160;30, 2022 and 3.25% at December 31, 2021) plus (ii) 2%. At June&#160;30, 2022 and December&#160;31, 2021, the annualized interest rate, which includes interest fees and the annual facility fee, was 8.4% and 8.0%, respectively. The annualized interest rate on the collateral management fee was 5.9% at both June&#160;30, 2022 and December&#160;31, 2021. The Receivables Facility is also secured by substantially all of the present and future assets of the Borrower and is also governed by an intercreditor agreement among the Company, the IF Lender and the RF Lender. A $25 thousand, or 1%, facility fee was charged at closing. There would be no breakage fee for the Company for the Receivables Facility if the Company were to refinance it with an ABA equivalent institution. The Receivables Facility matures on August 11, 2022, subject to early termination in accordance with the terms of the Receivables Loan Agreement, provided that the term is automatically extended in successive one (1) year increments unless terminated by either party in accordance with the Receivables Loan Agreement.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Borrowings under the Inventory Facility were $1.2 million at both June&#160;30, 2022 and December&#160;31, 2021.

However, due to changes in our capital structure, approximately $71.0 million of the $125.4 million is available to offset future taxable income after the application of the limitations found under Section 382 of the Internal Revenue Code of 1986, as amended. As a result of the Tax Cuts and Jobs Act of 2017 (the &#8220;Tax Act&#8221;), net operating loss carry-forwards generated in tax years beginning after December 31, 2017 can only offset 80% of taxable income and can be carried forward indefinitely. The $9.6 million and $7.1 million in federal net operating losses generated in 2021 and 2020, respectively, will be subject to the new limitations under the Tax Act. If not utilized, the carry-forwards generated prior to December 31, 2017 of $37.5 million will begin to expire in 2023 for federal purposes and have begun to expire for state and local purposes. For a full discussion of the estimated restrictions on our utilization of net operating loss carry-forwards, please refer to Note 11, &#8220;Income Taxes,&#8221; included under Item 8, &#8220;Financial Statements and Supplementary Data,&#8221; of our 2021 Annual Report.</span></div><span></span>

The ERTC was subsequently amended by the Taxpayer Certainty and Disaster Tax Relief Act of 2020, the Consolidated Appropriation Act of 2021, and the American Rescue Plan Act of 2021, all of which amended and extended the ERTC availability and guidelines under the CARES Act. Following these amendments, we and other businesses became retroactively eligible for the ERTC, and as a result of the foregoing legislation, are eligible to claim a refundable tax credit against the employer share of Social Security taxes equal to 70% of the qualified wages paid to employees between January 1, 2021 and September 30, 2021. Qualified wages are limited to $10,000 per employee per calendar quarter in 2021 for a maximum allowable ERTC per employee of $7,000 per calendar quarter in 2021. </span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For purposes of the amended ERTC, an eligible employer is defined as having experienced a significant (20% or more) decline in gross receipts during each of the first three 2021 calendar quarters when compared with the same quarter in 2019 or the immediately preceding quarter to the corresponding calendar quarter in 2019. The credit is taken against the Company&#8217;s share of Social Security Tax when the Company&#8217;s payroll provider files, or subsequently amends the applicable quarterly employer tax filings.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Under the amended guidelines, we are eligible to receive the ERTC for the second and third quarters of 2021. As part of the filing of our employer tax filings for the third quarter of 2021, we applied for and received a refund of $431&#160;thousand, and we amended our filing for the second quarter of 2021, for which we expect to receive an additional refund of approximately $445&#160;thousand. These amounts are recorded as other income in the Condensed Consolidated Statements of Operations during the quarter ended December&#160;31, 2021, and the $445&#160;thousand expected receivable is included in prepaid and other current assets in the Condensed Consolidated Balance Sheet as of June&#160;30, 2022 and December&#160;31, 2021.</span></div><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">PPP Loan</span></div>On April&#160;17, 2020, the Company was granted a loan from KeyBank in the amount of approximately $795&#160;thousand, pursuant to the PPP under the CARES Act, which was enacted on March 27, 2020. The funds were received on April 20, 2020 and accrued interest at a rate of 1% per annum. Under the terms of the PPP, certain amounts of the loan may be forgiven if they are used for qualifying expenses as described in the CARES Act. The entire principal balance and interest were forgiven by the SBA on February 11, 2021. The $801 thousand forgiveness income was recorded as other income in the Condensed Consolidated Statements of Operations during the six months ended June 30, 2021<span></span>

Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives of property and equipment; valuation allowance for net deferred taxes; the cost and offsetting income related to sub-leased property; and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment.

We maintain allowances for sales returns and doubtful accounts receivable to provide for the estimated number of account receivables that will not be collected. The allowance is based on an assessment of customer creditworthiness and historical payment experience, the age of outstanding receivables, and performance guarantees to the extent applicable. Past due amounts are written off when our internal collection efforts have been unsuccessful, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts.

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management&#x2019;s best knowledge of current events and actions that may impact us in the future, actual results may vary from the estimates. Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives of property and equipment; valuation allowance for net deferred taxes; the cost and offsetting income related to sub-leased property; and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment. Actual results could differ from those estimates and such differences could be material.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Certain risks and concentrations&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We have certain customers whose net sales individually represented 10% or more of our total net sales, or whose net trade accounts receivable balance individually represented 10% or more of our total net trade accounts receivable; we have certain suppliers, which individually represent 10% or more of our total purchases, or whose trade accounts payable balance individually represented 10% or more of our total trade accounts payable balance, as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;For the three months ended June 30, 2022, sales to our primary distributor for the U.S. Navy, a regional commercial lighting retrofit company, and a commercial building systems provider accounted for approximately 22%, 14%, and 13% of net sales, respectively.

The new guidance introduces an approach based on expected losses to estimate credit losses on certain financial instruments, including trade receivables, and requires an entity to recognize an allowance based on its estimate of expected credit losses rather than incurred losses. For smaller reporting companies, this standard will be effective for interim and annual periods starting after December 15, 2022 and will generally require adoption on a modified retrospective basis. We are in the process of evaluating the impact of the standard but do not expect any material financial statement impact upon adoption.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Revenue&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Net sales include revenues from sales of products and shipping and handling charges, net of estimates for product returns. Revenue is measured at the amount of consideration we expect to receive in exchange for the transferred products. We recognize revenue at the point in time when we transfer the promised products to the customer and the customer obtains control over the products. Distributors&#x2019; obligations to us are not contingent upon the resale of our products. We recognize revenue for shipping and handling charges at the time the goods are shipped to the customer, and the costs of outbound freight are included in cost of sales. We provide for product returns based on historical return rates. While we incur costs for sales commissions to our sales employees and outside agents, we recognize commission costs concurrent with the related &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;revenue, as the amortization period is less than one year. We do not incur any other incremental costs to obtain contracts with our customers. Our product warranties are assurance-type warranties, which promise the customer that the products are as specified in the contract. Therefore, the product warranties are not a separate performance obligation and are accounted for as described below. Sales taxes assessed by governmental authorities are accounted for on a net basis and are excluded from net sales.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span

style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our trade accounts receivable consists of amounts billed to and currently due from customers. Our customers are concentrated in the United States. In the normal course of business, we extend unsecured credit to our customers related to the sale of our products. Credit is extended to customers based on an evaluation of the customer&#x2019;s financial condition and the amounts due are stated at their estimated net realizable value. We utilize a third-party account receivable insurance program with a very high credit worthy insurance company where we have the large majority of the accounts receivable insured with a portion of self-retention. This third party also provides credit-worthiness ratings and metrics that significantly assist us in evaluating the credit worthiness of both existing and new customers. We maintain allowances for sales returns and doubtful accounts receivable to provide for the estimated number of account receivables that will not be collected. The allowance is based on an assessment of customer creditworthiness and historical payment experience, the age of outstanding receivables, and performance guarantees to the extent applicable. Past due amounts are written off when our internal collection efforts have been unsuccessful, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. We do not generally require collateral from our customers.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our standard payment terms with customers are net 30 days from the date of shipment, and we do not generally offer extended payment terms to our customers, but exceptions are made in some cases for major customers or with particular orders. Accordingly, we do not adjust trade accounts receivable for the effects of financing, as we expect the period between the transfer of product to the customer and the receipt of payment from the customer to be in line with our standard payment terms.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Geographic information&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;All of our long-lived fixed assets are located in the United States. For the three months ended June 30, 2022, less than 1% of sales were attributable to customers outside the United States. For the six months ended June 30, 2022, approximately 1% of sales were attributable to customers outside the United States. For the three and six months ended June&#160;30, 2021, there were approximately 3% and 2%, respectively, of sales attributable to customers outside the United States. The geographic location of our net sales is derived from the destination to which we ship the product.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Net loss per share &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period, excluding the effects of any potentially dilutive securities. Diluted loss per share gives effect to all dilutive potential shares of common stock outstanding during the period. Dilutive potential shares of common stock consist of incremental shares upon the exercise of stock options, warrants and convertible securities, unless the effect would be anti-dilutive.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New

Warranty settlement costs consist of actual amounts expensed for warranty, which are largely a result of the cost of replacement products provided to our customers. A liability for the estimated future costs under product warranties is maintained for products under warranty based on the actual claims incurred to date and the estimated nature, frequency, and costs of future claims. These estimates are inherently uncertain and changes to our historical or projected experience may cause material changes to our warranty reserves in the future. We continuously review the assumptions related to the adequacy of our warranty reserve, including product failure rates, and make adjustments to the existing warranty liability when there are changes to these estimates or the underlying replacement product costs, or the warranty period expires.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span

In determining the appropriate levels, we perform a detailed analysis of the assets and liabilities whose fair value is measured on a recurring basis. We review and reassess the fair value hierarchy classifications on a quarterly basis. Changes from one quarter to the next related to the observability of inputs in a fair value measurement may result in a reclassification between fair value hierarchy levels.

Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives of property and equipment; valuation allowance for net deferred taxes; the cost and offsetting income related to sub-leased property; and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment. Actual results could differ from those estimates and such differences could be material.&lt;/span&gt;&lt;/div&gt;</us-gaap:UseOfEstimates>

The new guidance introduces an approach based on expected losses to estimate credit losses on certain financial instruments, including trade receivables, and requires an entity to recognize an allowance based on its estimate of expected credit losses rather than incurred losses. For smaller reporting companies, this standard will be effective for interim and annual periods starting after December 15, 2022 and will generally require adoption on a modified retrospective basis. We are in the process of evaluating the impact of the standard but do not expect any material financial statement impact upon adoption.&lt;/span&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Revenue is measured at the amount of consideration we expect to receive in exchange for the transferred products. We recognize revenue at the point in time when we transfer the promised products to the customer and the customer obtains control over the products. Distributors&#x2019; obligations to us are not contingent upon the resale of our products. We recognize revenue for shipping and handling charges at the time the goods are shipped to the customer, and the costs of outbound freight are included in cost of sales. We provide for product returns based on historical return rates. While we incur costs for sales commissions to our sales employees and outside agents, we recognize commission costs concurrent with the related &lt;/span&gt;&lt;/div&gt;revenue, as the amortization period is less than one year. We do not incur any other incremental costs to obtain contracts with our customers. Our product warranties are assurance-type warranties, which promise the customer that the products are as specified in the contract. Therefore, the product warranties are not a separate performance obligation and are accounted for as described below. Sales taxes assessed by governmental authorities are accounted for on a net basis and are excluded from net sales.</us-gaap:RevenueRecognitionPolicyTextBlock>

Our customers are concentrated in the United States. In the normal course of business, we extend unsecured credit to our customers related to the sale of our products. Credit is extended to customers based on an evaluation of the customer&#x2019;s financial condition and the amounts due are stated at their estimated net realizable value. We utilize a third-party account receivable insurance program with a very high credit worthy insurance company where we have the large majority of the accounts receivable insured with a portion of self-retention. This third party also provides credit-worthiness ratings and metrics that significantly assist us in evaluating the credit worthiness of both existing and new customers. We maintain allowances for sales returns and doubtful accounts receivable to provide for the estimated number of account receivables that will not be collected. The allowance is based on an assessment of customer creditworthiness and historical payment experience, the age of outstanding receivables, and performance guarantees to the extent applicable. Past due amounts are written off when our internal collection efforts have been unsuccessful, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. We do not generally require collateral from our customers.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our standard payment terms with customers are net 30 days from the date of shipment, and we do not generally offer extended payment terms to our customers, but exceptions are made in some cases for major customers or with particular orders. Accordingly, we do not adjust trade accounts receivable for the effects of financing, as we expect the period between the transfer of product to the customer and the receipt of payment from the customer to be in line with our standard payment terms.&lt;/span&gt;&lt;/div&gt;</us-gaap:TradeAndOtherAccountsReceivableUnbilledReceivablesPolicy>

Warranty settlement costs consist of actual amounts expensed for warranty, which are largely a result of the cost of replacement products provided to our customers. A liability for the estimated future costs under product warranties is maintained for products under warranty based on the actual claims incurred to date and the estimated nature, frequency, and costs of future claims. These estimates are inherently uncertain and changes to our historical or projected experience may cause material changes to our warranty reserves in the future. We continuously review the assumptions related to the adequacy of our warranty reserve, including product failure rates, and make adjustments to the existing warranty liability when there are changes to these estimates or the underlying replacement product costs, or the warranty period expires.&lt;/span&gt;&lt;/div&gt;</us-gaap:StandardProductWarrantyPolicy>

In determining the appropriate levels, we perform a detailed analysis of the assets and liabilities whose fair value is measured on a recurring basis. We review and reassess the fair value hierarchy classifications on a quarterly basis. Changes from one quarter to the next related to the observability of inputs in a fair value measurement may result in a reclassification between fair value hierarchy levels.

For additional information regarding the restructuring actions taken as part of the restructuring plans, please refer to Note 3, &#x201c;Restructuring,&#x201d; included under Item&#160;8, &#x201c;Financial Statements and Supplementary Data,&#x201d; of our 2021 Annual Report.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The lease obligation on our former New York, New York office was settled as of June 30, 2021. Our restructuring liabilities consisted of estimated ongoing costs related to long-term operating lease obligations, which the Company exited. The recorded value of the lease obligation was based on the remaining lease term and payment amount, discounted to present value. Changes in subsequent periods resulting from a revision to either the timing or the amount of estimated cash flows over the future period were measured using the credit adjusted, risk free rate that

As described in Note 7, &#x201c;Debt&#x201d;, in April 2022 and April 2021, we obtained net proceeds from bridge financing of approximately $1.8 million and $1.5 million, respectively. Also in April 2021, we expanded the borrowing capacity on one of our revolving credit facilities.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The restructuring and cost cutting initiatives taken throughout 2021 and continuing into 2022, as well as the June 2022 Private Placement, the December 2021 Private Placement and the June 2021 Equity Offering that strengthened our balance sheet, our credit facility capacity increase and bridge financings in April 2022 and April 2021, and the funds we expect to receive related to the Employee Retention Tax Credit (&#x201c;ERTC&#x201d;; see Note 11, &#x201c;Other Income&#x201d; for details), were all designed to allow us to effectively execute these strategies. However, our efforts may not occur as quickly as we envision or be successful due to the long sales cycle in our industry, the corresponding time and inventory management required to ramp up sales from new products, markets, and customers into this sales cycle, the timing of introductions of additional new products, significant competition, potential sales volatility given our customer concentration, numerous interruptions and cost increases in the supply chain globally, and the long-term economic impact from the COVID-19 pandemic that has significantly diminished the interest and activities for our customers&#x2019; lighting retrofit projects until occupancy returns to more normal levels, among other factors.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Additionally, global supply chain and logistics constraints are impacting our inventory purchasing strategy, as we seek to manage both shortages of available components and longer lead times in obtaining components while balancing the development and implementation of an inventory reduction plan. Disruptions in global logistics networks are also impacting our lead times and ability to efficiently and cost-effectively transport products from our third-party suppliers to our facility. As a result, we will continue to review and pursue selected external funding sources to ensure adequate financial resources to execute across the timelines required to achieve these objectives including, but not limited to, the following:&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;obtaining financing from traditional or non-traditional investment capital organizations or individuals; &lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;obtaining funding from the sale of our common stock or other equity or debt instruments; and&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:14.5pt"&gt;obtaining debt financing with lending terms that more closely match our business model and capital needs.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;There can be no assurance that we will obtain funding on acceptable terms, in a timely fashion, or at all.

If we fail to obtain the required additional financing to sustain our business before we are able to produce levels of revenue to meet our financial needs, we will need to delay, scale back or eliminate our growth plans and further reduce our operating costs and headcount, each of which would have a material adverse effect on our business, future prospects, and financial condition. A lack of additional funding could also result in our inability to continue as a going concern and force us to sell certain assets or discontinue or curtail our operations and, as a result, investors in the Company could lose their entire investment.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Considering both quantitative and qualitative information, we continue to believe that the combination of our plans to ensure adequate external funding, timely re-organizational actions, current financial position, liquid resources, obligations due or anticipated within the next year, development and implementation of an excess inventory reduction plan, plans and initiatives in our research and development, product development and sales and marketing, and development of potential channel partnerships, if adequately executed, will provide us with an ability to finance our operations through the next twelve months and will mitigate the substantial doubt about our ability to continue as a going concern.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt;On August 17, 2020, we received a letter from the Listing Qualifications staff (the &#x201c;Staff&#x201d;) of The Nasdaq Stock Market (&#x201c;Nasdaq&#x201d;) notifying us that we were no longer in compliance with Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain stockholders&#x2019; equity of at least $2,500,000 if they do not meet the alternative compliance standards relating to the market value of listed securities or net income from continuing operations (the &#x201c;Minimum Stockholders&#x2019; Equity Rule&#x201d;). Our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2020, filed on August 13, 2020, reflected that our stockholders&#x2019; equity as of June 30, 2020 was $1,714,000. Based on our timely submission of our plan to regain compliance, Nasdaq granted us an extension through February 15, 2021 to regain compliance with the Minimum Stockholders&#x2019; Equity Rule. In accordance with one part of the plan submitted to the Staff, we successfully modified our outstanding January 2020 Warrants and in December 2020, we reclassified $1.4&#160;million from warrant liability into equity. On January 20, 2021, we received a letter from the Staff notifying us that, on a conditional basis, Nasdaq has determined that we have regained compliance with the Minimum Stockholders&#x2019; Equity Rule. At December 31, 2020, our stockholders&#x2019; equity was $4,255,000, satisfying the Minimum Stockholders&#x2019; Equity Rule. At December&#160;31, 2021, our stockholders&#x2019; equity was $6,209,000 and at June&#160;30, 2022, our stockholders&#x2019; equity was $4,171,000.&lt;/span&gt;&lt;/div&gt;</us-gaap:RestructuringAndRelatedActivitiesDisclosureTextBlock>

warehouse space beginning in the third quarter of 2022. In connection with the space reduction, in the second quarter of 2022, we began disposing of a substantial portion of our excess and obsolete commercial finished goods inventory that was more than 90% reserved. As of June 30, 2022, approximately $204&#160;thousand of such inventory had been disposed of. Additional inventory management efforts are expected to continue in the third quarter of 2022 in order to free up additional space in the warehouse.&lt;/span&gt;&lt;/div&gt;</us-gaap:InventoryDisclosureTextBlock>

The Company had one finance lease containing a bargain purchase option that was not renewed upon expiration of the lease during the second quarter of 2022. The lease term consists of the non-cancellable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option. As of January 21, 2021, the terms of one of our equipment operating leases had been extended through 2026. Additionally, as of March 25, 2022, in connection with extending through 2027, the terms of our expiring headquarters real estate operating lease for manufacturing, warehouse and office space have been modified beginning July 1, 2022 to reflect a smaller footprint at reduced costs. In accordance with Accounting Standards Codification 842, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Leases&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; (&#x201c;Topic 842&#x201d;), as a result of the extension, the related lease liability was remeasured and the right-of-use asset was adjusted for each lease at the time of modification in January 2021 and March 2022. The present value of the lease obligations for these leases were calculated using an incremental borrowing rate of 15.93% for the equipment lease and 16.96% for the real estate lease, which were the Company&#x2019;s blended borrowing rates (including interest, annual facility fees, collateral management fees, bank fees and other miscellaneous lender fees) on its revolving lines of credit with Crossroads Financial Group, LLC (as described below in Note 7, &#x201c;Debt&#x201d;) and Factors Southwest L.L.C. (as described below in Note 7, &#x201c;Debt&#x201d;). The present value of the other remaining lease obligations continues to be calculated using an incremental borrowing rate of 7.25% (which excludes the annual facility fee and other lender fees), which was the Company&#x2019;s borrowing rate on its former revolving line of credit with Austin Financial Services, Inc. (the &#x201c;Austin Credit Facility&#x201d;). The weighted average remaining lease term for the operating leases is 4.9 years.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company had one restructured lease with a sub-lease component for the New York, New York office that was closed in 2017. The lease expired in June 2021.

The Company had one finance lease containing a bargain purchase option that was not renewed upon expiration of the lease during the second quarter of 2022. The lease term consists of the non-cancellable period of the lease, periods covered by options to extend the lease if the Company is reasonably certain to exercise the option, and periods covered by an option to terminate the lease if the Company is reasonably certain not to exercise the option. As of January 21, 2021, the terms of one of our equipment operating leases had been extended through 2026. Additionally, as of March 25, 2022, in connection with extending through 2027, the terms of our expiring headquarters real estate operating lease for manufacturing, warehouse and office space have been modified beginning July 1, 2022 to reflect a smaller footprint at reduced costs. In accordance with Accounting Standards Codification 842, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Leases&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; (&#x201c;Topic 842&#x201d;), as a result of the extension, the related lease liability was remeasured and the right-of-use asset was adjusted for each lease at the time of modification in January 2021 and March 2022. The present value of the lease obligations for these leases were calculated using an incremental borrowing rate of 15.93% for the equipment lease and 16.96% for the real estate lease, which were the Company&#x2019;s blended borrowing rates (including interest, annual facility fees, collateral management fees, bank fees and other miscellaneous lender fees) on its revolving lines of credit with Crossroads Financial Group, LLC (as described below in Note 7, &#x201c;Debt&#x201d;) and Factors Southwest L.L.C. (as described below in Note 7, &#x201c;Debt&#x201d;). The present value of the other remaining lease obligations continues to be calculated using an incremental borrowing rate of 7.25% (which excludes the annual facility fee and other lender fees), which was the Company&#x2019;s borrowing rate on its former revolving line of credit with Austin Financial Services, Inc. (the &#x201c;Austin Credit Facility&#x201d;). The weighted average remaining lease term for the operating leases is 4.9 years.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company had one restructured lease with a sub-lease component for the New York, New York office that was closed in 2017. The lease expired in June 2021. The restructured lease and sub-lease were deemed to be in-scope and thus subject to the requirements of Topic 842 and were evaluated for impairment in accordance with the asset impairment provisions of Accounting Standards Codification 360, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Property, Plant and Equipment&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; (&#x201c;Topic 360&#x201d;). The Company concluded its net right-of-use assets were not impaired and the carrying amount approximates expected sublease income in future years as of December&#160;31, 2020. The Company continued to carry certain immaterial operating expenses associated with this lease as restructuring liabilities and continued to accrete those liabilities in accordance with Accounting Standards Codification 420, &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Exit or Disposal Cost Obligations&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; (&#x201c;Topic 420&#x201d;), as has been done since the cease use date in 2017.

The first arrangement is an inventory financing facility (the &#x201c;Inventory Facility&#x201d;) pursuant to the Loan and Security Agreement (the &#x201c;Inventory Loan Agreement&#x201d;) between the Company and Crossroads Financial Group, LLC, a North Carolina limited liability company (the &#x201c;IF Lender&#x201d;). Borrowings under the original Inventory Facility were permitted up to the lower of (i) $3.0 million, which amount was subsequently increased to $3.5 million as described below, and (ii) a borrowing base determined from time to time based on the value of the Company&#x2019;s eligible inventory, valued at 75% of inventory costs or 85% of the inventory net orderly liquidation value, less the availability reserves. On April 20, 2021, the Company and the IF Lender entered into an amendment to the Inventory Loan Agreement to increase the maximum amount that may be available to the Company from $3.0 million to $3.5 million, subject to the borrowing base as set forth in the Inventory Loan Agreement. The outstanding indebtedness under the Inventory Facility accrues at an annual rate equal to the greater of (i) 5.75% and (ii) 4.00% plus the three-month LIBOR rate (2.29% and 0.21% at June&#160;30, 2022 and December&#160;31, 2021, respectively) and is also subject to a service fee of 1% per month. The annualized interest rate at June&#160;30, 2022 and December&#160;31, 2021, which includes interest fees, the annual facility fee, bank fees and other miscellaneous lender fees, was 22.1% and 22.4%, respectively. The Inventory Facility&#x2019;s interest and service fees combined amount is subject to a minimum monthly fee of $18 thousand. There would be no breakage fee for the Company for the Inventory Facility if the Company were to refinance it with an American Bankers Association (&#x201c;ABA&#x201d;) equivalent institution. The Inventory Facility is secured by substantially all of the present and future assets of the Company and is also governed by an intercreditor agreement among the Company, the IF Lender and the RF Lender (defined below). The Inventory Facility matures on August 11, 2022, subject to early termination upon 90 days&#x2019; notice and otherwise in accordance with the terms of the Inventory Loan Agreement. The term is automatically extended in successive one (1) year increments unless terminated by either party in accordance with the Inventory Loan Agreement.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The second arrangement is a receivables financing facility (the &#x201c;Receivables Facility&#x201d;) pursuant to the Loan and Security Agreement (the &#x201c;Receivables Loan Agreement&#x201d;) between the Company and Factors Southwest L.L.C. (d/b/a FSW Funding), an Arizona limited liability company (the &#x201c;RF Lender&#x201d;). Borrowings under the Receivables Facility are permitted up to the lower of (i) $2.5 million and (ii) a borrowing base determined from time to time based on the value of the Company&#x2019;s eligible accounts receivable, valued at 90% of the face value of such accounts receivable, less availability reserves, if any. Interest on outstanding indebtedness under the Receivables Facility accrues at an annual rate equal to (i) the highest prime rate announced from time to time by the Wall Street Journal (4.75% at June&#160;30, 2022 and 3.25% at December 31, 2021) plus (ii) 2%. At June&#160;30, 2022 and December&#160;31, 2021, the annualized interest rate, which includes interest fees and the annual facility fee, was 8.4% and 8.0%, respectively. The annualized interest rate on the collateral management fee was 5.9% at both June&#160;30, 2022 and December&#160;31, 2021. The Receivables Facility is also secured by substantially all of the present and future assets of the Borrower and is also governed by an intercreditor agreement among the Company, the IF Lender and the RF Lender. A $25 thousand, or 1%, facility fee was charged at closing. There would be no breakage fee for the Company for the Receivables Facility if the Company were to refinance it with an ABA equivalent institution. The Receivables Facility matures on August 11, 2022, subject to early termination in accordance with the terms of the Receivables Loan Agreement, provided that the term is automatically extended in successive one (1) year increments unless terminated by either party in accordance with the Receivables Loan Agreement.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Borrowings under the Inventory Facility were $1.2 million at both June&#160;30, 2022 and December&#160;31, 2021. Borrowings under the Receivables Facility were $0.7 million and $1.0 million at June&#160;30, 2022 and December&#160;31, 2021, respectively. These Credit Facilities are recorded in the Condensed Consolidated Balance Sheets as of June&#160;30, 2022 and December&#160;31, 2021 as a current liability under the caption &#x201c;Credit line borrowings.&#x201d; Outstanding balances include unamortized net issuance costs totaling $18 thousand and $84 thousand for the Inventory Facility and $4 thousand and $24 thousand for the Receivables Facility as of June&#160;30, 2022 and December&#160;31, 2021, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;Streeterville Notes&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;2022 Note&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;On April&#160;21, 2022, we entered into a note purchase agreement (the &#x201c;2022 Streeterville Note Purchase Agreement&#x201d;) with Streeterville Capital, LLC (&#x201c;Streeterville&#x201d;) pursuant to which we sold and issued to Streeterville a promissory note in the principal amount of approximately $2.0 million (the &#x201c;2022 Streeterville Note&#x201d;). The 2022 Streeterville Note was issued with an original issue discount of $215 thousand and Streeterville paid a purchase price of approximately $1.8 million for the 2022 Streeterville Note, from which the Company paid $15 thousand to Streeterville for Streeterville&#x2019;s transaction expenses.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The 2022 Streeterville Note has a maturity date of April&#160;21, 2024, and accrues interest at 8% per annum, compounded daily, on the outstanding balance.

The 2021 Streeterville Note was issued with an original issue discount of $194 thousand and Streeterville paid a purchase price of $1.5 million for the 2021 Streeterville Note, after deduction of $15 thousand of Streeterville&#x2019;s transaction expenses.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The 2021 Streeterville Note has a maturity date of April&#160;27, 2023, and accrues interest at 8% per annum, compounded daily, on the outstanding balance.

The funds were received on April 20, 2020 and accrued interest at a rate of 1% per annum. Under the terms of the PPP, certain amounts of the loan may be forgiven if they are used for qualifying expenses as described in the CARES Act. The entire principal balance and interest were forgiven by the Small Business Administration (&#x201c;SBA&#x201d;) on February 11, 2021. The $801 thousand forgiveness income was recorded as other income in the Condensed Consolidated Statements of Operations during the six months ended June 30, 2021.&lt;/span&gt;&lt;/div&gt;</us-gaap:DebtDisclosureTextBlock>

The valuation allowance is based on management&#x2019;s estimates of taxable income by jurisdiction and the periods over which the deferred tax assets will be recoverable.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;padding-right:4.5pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;At December&#160;31, 2021, we had a net operating loss carry-forward of approximately $125.4 million for federal income tax purposes ($77.2 million for state and local income tax purposes). However, due to changes in our capital structure, approximately $71.0 million of the $125.4 million is available to offset future taxable income after the application of the limitations found under Section 382 of the Internal Revenue Code of 1986, as amended. As a result of the Tax Cuts and Jobs Act of 2017 (the &#x201c;Tax Act&#x201d;), net operating loss carry-forwards generated in tax years beginning after December 31, 2017 can only offset 80% of taxable income and can be carried forward indefinitely. The $9.6 million and $7.1 million in federal net operating losses generated in 2021 and 2020, respectively, will be subject to the new limitations under the Tax Act. If not utilized, the carry-forwards generated prior to December 31, 2017 of $37.5 million will begin to expire in 2023 for federal purposes and have begun to expire for state and local purposes. For a full discussion of the estimated restrictions on our utilization of net operating loss carry-forwards, please refer to Note 11, &#x201c;Income Taxes,&#x201d; included under Item 8, &#x201c;Financial Statements and Supplementary Data,&#x201d; of our 2021 Annual Report.&lt;/span&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

The ERTC was subsequently amended by the Taxpayer Certainty and Disaster Tax Relief Act of 2020, the Consolidated Appropriation Act of 2021, and the American Rescue Plan Act of 2021, all of which amended and extended the ERTC availability and guidelines under the CARES Act. Following these amendments, we and other businesses became retroactively eligible for the ERTC, and as a result of the foregoing legislation, are eligible to claim a refundable tax credit against the employer share of Social Security taxes equal to 70% of the qualified wages paid to employees between January 1, 2021 and September 30, 2021. Qualified wages are limited to $10,000 per employee per calendar quarter in 2021 for a maximum allowable ERTC per employee of $7,000 per calendar quarter in 2021. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;For purposes of the amended ERTC, an eligible employer is defined as having experienced a significant (20% or more) decline in gross receipts during each of the first three 2021 calendar quarters when compared with the same quarter in 2019 or the immediately preceding quarter to the corresponding calendar quarter in 2019. The credit is taken against the Company&#x2019;s share of Social Security Tax when the Company&#x2019;s payroll provider files, or subsequently amends the applicable quarterly employer tax filings.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Under the amended guidelines, we are eligible to receive the ERTC for the second and third quarters of 2021. As part of the filing of our employer tax filings for the third quarter of 2021, we applied for and received a refund of $431&#160;thousand, and we amended our filing for the second quarter of 2021, for which we expect to receive an additional refund of approximately $445&#160;thousand. These amounts are recorded as other income in the Condensed Consolidated Statements of Operations during the quarter ended December&#160;31, 2021, and the $445&#160;thousand expected receivable is included in prepaid and other current assets in the Condensed Consolidated Balance Sheet as of June&#160;30, 2022 and December&#160;31, 2021.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%"&gt;PPP Loan&lt;/span&gt;&lt;/div&gt;On April&#160;17, 2020, the Company was granted a loan from KeyBank in the amount of approximately $795&#160;thousand, pursuant to the PPP under the CARES Act, which was enacted on March 27, 2020. The funds were received on April 20, 2020 and accrued interest at a rate of 1% per annum. Under the terms of the PPP, certain amounts of the loan may be forgiven if they are used for qualifying expenses as described in the CARES Act. The entire principal balance and interest were forgiven by the SBA on February 11, 2021. The $801 thousand forgiveness income was recorded as other income in the Condensed Consolidated Statements of Operations during the six months ended June 30, 2021</us-gaap:OtherIncomeAndOtherExpenseDisclosureTextBlock>
