Nature of Operations

NATURE OFOPERATIONS

Energy Focus, Inc. and its subsidiary engage in the design, development, manufacturing, marketing, and sale of energy-efficient lighting systems. We operate in a single industry segment, developing and selling our energy-efficient light-emitting diode (“LED”) lighting products into the military maritime and general commercial and industrial markets. We have aligned our resources and focused our efforts on the sale of our LED lighting products, in particular our military and commercial tubular LED (“TLED”) lines of products, into targeted vertical markets.

During 2014, we shifted our focus away from the turnkey solutions business of Energy Focus LED Solutions, LLC ("EFLS"), which has historically incurred lower gross margins. We completed all outstanding solutions-based projects in the first quarter of 2015, are no longer accepting new projects, and fully exited the business as of September 2015. In August 2015, we sold our United Kingdom subsidiary, Crescent Lighting Limited ("CLL"). In 2013, we sold and discontinued our pool products business. As a result of exiting the turnkey solutions, CLL, and the pool products businesses, we have eliminated all net sales and expenses associated with those businesses from the Condensed Consolidated Statements of Operations and have reported the net losses as discontinued operations. Please refer to Note 3, "Discontinued Operations," for more information on our disposition of these businesses.
