PRODUCT AND GEOGRAPHIC INFORMATION
 
During 2013, we sold our pool products business. During 2014, we shifted our focus away from the turnkey solutions business to align our resources with developing and selling our LED products and completed our exit of that business in September 2015. With the exit from EFLS and sale of CLL, we have aligned our resources and focused our efforts on the sale of LED lighting products, in particular our military and commercial tubular LED (“TLED”) lines of products, into targeted vertical markets. Our products are sold primarily in the United States through a combination of direct sales employees, independent sales representatives and distributors. We currently operate in a single industry segment, developing and selling our energy-efficient light-emitting diode (“LED”) lighting products into the military maritime and commercial markets.
