Nature of Operations [Text Block] | 1. Nature of Operations The Company engages in the design, development, manufacturing, marketing, and installation of energy-efficient lighting systems and solutions where we serve two segments:
| ● | Products: providing military, general commercial and industrial energy-efficient lighting offerings; and
| ● | Solutions: providing turnkey, high-quality, energy-efficient lighting application alternatives, primarily to the existing public-sector building market.
In November 2013, the Company sold and discontinued its pool products business, and is focusing its resources solely on the LED lighting retrofit business. The “Gain (loss) from discontinued operations” caption on the Company’s Consolidated Statements of Operations included in this Item 8 includes the operations associated with the pool products business. See Note 3, Sale of Discontinued Operations, for further information relating to the sale of this business.
