Exhibit 99.1

ENERGY FOCUS, INC. REPORTS FIRST QUARTER 2013 RESULTS

SOLON, Ohio, May 15, 2013 -- Energy Focus, Inc. (OTCQB:EFOI) a global leader in energy-efficient lighting technologies, today announced financial results for the first quarter ended March 31, 2013.

Financial results for the quarter include the following:

● Net sales of $5.3 million for the first quarter of 2013 and 2012.

● Gross margins of 22.5 percent of net sales compared to 14.8 percent of net sales for the first quarter of 2012.

● A net loss of $1.4 million compared to a net loss $1.9 million in the first quarter of 2012.

Net sales for the first quarter of 2013 were comparable to the prior year’s first quarter. Solutions segment sales increased 10 percent, while products segment sales decreased four percent, due to lower government products sales resulting from the timing of order receipts due to the sequester.

James Tu, Executive Chairman, commented: “Our first quarter sales came in modestly lower than our previous guidance due to a delay in Navy orders as a result of the sequester and sales that took longer to recognize in our lighting retrofit division, Stones River Companies (SRC). However, as we have stated in a recent press release, we have been witnessing much stronger momentum in SRC’s business this year, with 50% growth in contracts over the same period last year. We’re also excited to announce that, despite the government sequester, our Navy business has obtained an additional $1.9 million in orders so far in the second quarter; a trend that we expect to continue, leading to substantial growth in our Navy business in 2013.”

“We believe that the LED revolution has started to reach the lighting retrofit market,” continued Mr. Tu. “We are particularly excited about the increasing appeal of our LED lighting solutions over fluorescent even in projects that have fewer hours of operation, such as schools. In addition, under the new leadership Energy Focus has put in place, we’re embarking on a series of operational initiatives that aim to unlock our organizational potential and create shareholder value. Therefore, in spite of a slow first quarter, we do look forward to a year of strong growth.”

During the first quarter of 2013, the Company embarked on a program to raise an additional $3.8 million in unsecured convertible debt, of which $1.75 million was received during the first quarter. During the second quarter, the Company expects to receive an additional $2 million. “We are grateful and pleased to have received strong investor support during the current round of financing which will enable us to meet our growing working capital needs and reach our goal to be EBITDA positive in the second half of this year,” added Mr. Tu.

The Company expects sales for the second quarter of 2013 to range between $8 million and $9 million, and expects sales will continue to grow in the second half of the year.
