Lighting Science Group launches portfolio of LED replacement lamps

Date Announced: 09 Apr 2008 Broadest Range of LED Lamps in the Industry Offer High-Performing, Energy Efficient, and Environmentally Safe Light SourceLighting Science Group (OTC BB: LSCG) (LSG), a leading developer and manufacturer of intelligent and energy-efficient light emitting diode (LED) lighting solutions, has launched the industry’s widest line of replacement LED lamps for both commercial and residential lighting applications. The simple, uniquely designed lamps offer unparalleled light output, matching traditional technology at a fraction of the energy consumption. The new line delivers unprecedented levels of energy efficiency, light quality and output as compared with other options. The unique design optimizes the lamp’s thermal management, enabling a life of up to 50,000 hours (10-30 years). The lamps consume 80 percent less energy than conventional lighting sources, while matching light output. The company is initially targeting the estimated five billion Edison-based sockets in North America.LSG’s new portfolio features the lighting industry’s most extensive range of LED lamps, consisting of six different styles of Edison-based lamps in both cool and warm white and in narrow and wide beam distributions.“The unrivaled performance of our new LED lamps will significantly reduce lifetime operating costs for customers,” said Govi Rao, chief executive officer of Lighting Science Group. “Our technological leadership allows us to offer the most environmentally friendly solutions without compromising performance.” LED options require $738.40 less in total spending than incandescent bulbs and $72.49 less than compact fluorescent light bulbs (productdose.com). By 2025, rapid adoption of LEDs in the United States alone can eliminate a cumulative 258 million metric tons of carbon emissions, save $115 billion in total electricity costs and avoid the construction of 133 new power plants (Optoelectronics Industry Development Association). Beyond energy savings, installing an LED lamp instead of a fluorescent bulb can save approximately two to four tons of mercury from being released into the atmosphere in the United States each year (Mercury Policy Project). LSG’s products are 100 percent recyclable and contain no hazardous materials such as mercury and lead. Through its EcoAdvantage initiative, Lighting Science is advancing LED technology and efficiency standards by developing innovative lighting solutions. The lamps can be used in various functions and applications including track, spot, accent, vanity and recessed lighting. The new portfolio of Lighting Science Group’s LED lamps will be showcased at Light & Building in Frankfurt, Germany and available for purchase on the company’s Web site. The lamps will also be sold through channel partners such as electrical distributors and energy-service companies.
