EfficientLights introduces LED lighting for retailers’ refrigeration

May 20, 2010
Date Announced: 20 May 2010 PowerSecure International, Inc. (Nasdaq: POWR) today announced its EfficientLights business has introduced two new LED lighting products to improve the energy efficiency and quality of light in grocery, drug, and convenience stores. These products include a new light for retailers’ walk-in freezer/coolers and a new light for open refrigerated shelves. These products broaden the Company’s in-store LED lighting product line, and complement its highly successful flagship EfficientLights product for refrigerated case doors. The new lights are being brought to market at the urging of customers who have installed and experienced the benefits of PowerSecure’s flagship LED product, and who have identified a strong marketplace need for these additional in-store LED lighting applications.The new lights were designed, tested, and perfected in real world settings, including operating grocery stores of major chains who have installed the Company’s flagship EfficientLights product. Importantly, they utilize and build upon the Company’s industry leading technology, and are designed to deliver retailers an improved quality of light illuminating their products. In addition, the new lighting solutions will reduce lighting energy costs, reduce maintenance expense by extending light life five-fold over traditional lighting, provide a lower carbon footprint, and eliminate the use of mercury-containing fluorescent lights. Bryan Beatenbough, President of EfficientLights, said, "We are very excited to bring these new products to market. We have been blessed to have a wonderfully successful EfficientLights refrigerated case door product that is improving energy efficiency and lighting in stores across the country, and we can now bring retailers these benefits to additional areas of their stores. Similar to the process we used to develop our flagship product, we designed our new lights in partnership with our customers – to make sure our light addresses their real-world needs. The release of these new lights to the marketplace represents another major milestone in our plan to bring retailers a full suite of LED lighting for their stores.”About PowerSecurePowerSecure International, Inc. is a leading provider of Energy and Smart Grid Solutions to electric utilities, and their commercial, institutional, and industrial customers, as well as Energy Services to the oil and natural gas industry.
