Date Announced: 17 Apr 2012 LIGHTING SCIENCE GROUP LAUNCHES WORLD’S MOST EFFICIENT LED MR16 50-WATT EQUIVALENT BULBNew Bulb Joins the Company’s Wide Selection of High Quality LED ProductsSatellite Beach, Florida, April 17, 2012 – Lighting Science Group (OTCBB: LSCG), the world’s premier LED lighting manufacturer, announced today the production launch of a revolutionary high output 8-watt LED MR16 bulb that is a direct replacement for traditional MR16 50-watt halogenbulbs. Suited to a variety of applications that require directional lighting—such as track lighting, recessed ceilinglights, desk lamps, pendant fixtures and retail display lighting—the DEFINITY™ MR16 HO LED bulb will be the first of its kind introduced to the marketplace, and considered the best of its breed when evaluated by metrics of efficiency, lumen output and form factor.The degree of difficulty involved in managing the MR16’s discreet size and internal power supply and the intense requirements for brightness of a 50-watt equivalent renders its design and manufacture a complex challenge. Competitive attempts at reaching these high levels of performance have resulted in concessions thathave been viewed as unacceptable to the market. No such sacrifice is required with the Definity MR16 HO Series. At only 8 watts and a 25,000 hour life rating, Lighting Science Group’s new DEFINITY™ MR16 HO LED bulb is up to 33% more efficient than competitive products while staying within the industry accepted form factor and not using any moving parts like fans to achieve its superior performance. “A commitment to superior technology underwrites all Lighting Science Group operations; that’s why our customers can rest assured that they’re offered the most advanced and widest selection of LED lighting products,” said Jim Haworth, chairman and chief executive officer of the Company. “We believe that our new MR16 HO, which couples unparalleled efficiency and incredible performance, is a significant advancement in the science of light and another step forward in the development of a more efficient, sustainable and brighter energy future.”The new bulb joins the Company’s suite of products that have found applications ranging from use in NASA outer space ventures; to artistic designs that span skyscraper silhouettes; to everyday, practical implementations for American homes and businesses that save families and business owners significant amounts of money on electricity bills. On the global stage, Lighting Science Group has become synonymous with the ultra-efficient lighting revolution, and at home the Company is most commonly viewed as the fulfillment of America's clean technology promise.To find your nearest sales location for Lighting Science Group’s DEFINITY™ bulbs, visit: To view a video about the Company's new bulb, visit: Lighting Science GroupLighting Science Group Corporation (OTCBB: LSCG) designs, develops, manufactures and markets LED lighting solutions that areenvironmentally friendlier and more energy efficient than traditional lighting products.
