Re.:  Energy Focus, Inc. Shares of Common Stock

Gentlemen:

Reference is made to our letter of October 28, 2009 ("October Letter") relating
to Energy Focus' Subscription Rights Offering, in which we agreed that Energy
Focus would repurchase from Diker Management and its affiliates shares that they
had purchased in the Offering if the two conditions contained in the October
Letter had not been satisfied.

This letter will confirm our understanding and agreement relating to our rights
and obligations in the October Letter. The October Letter will be deemed
satisfied if:

(i) By 11:59 p.m. Eastern Standard Time on Thursday, December 24, 2009 (the
"Initial Deadline"), Diker has received $750,000.00 for the repurchase of
1,000,000 of its Energy Focus shares. Energy Focus will use all reasonable
efforts in good faith to have those shares repurchased for that amount by that
date and time. An escrow account may be used for the execution of the
transaction. Upon receipt of the purchase price, Diker shall simultaneously or
as soon as possible transfer ownership of the shares to the escrow; or

(ii) If the shares have not been purchased by the Initial Deadline, no later
than 11:59 pm EST on Monday, December 28, 2009 (the "Final Deadline"), Energy
Focus itself will fund the escrow and have the escrow agent purchase the shares
from Diker with those funds.

If the purchase price has been received by Diker by the extended deadline, all
Energy Focus obligations in the October Letter shall be deemed satisfied.
