Lighting Science Launches New "Edison Inspired" Definity™ A19 LED Lamps

Lighting Science Group Corporation® (LSCG) announced today the launch of a revolutionary "Edison inspired" A19 and GP19 LED lamp as a direct replacement for traditional general purpose lighting. Created with the most advanced thermal materials available, these lamps are unmistakably lighter and more efficient, while less expensive, than ever before. These LED-optimized lamps truly replicate the form, weight and function of the incandescent Edison-shaped bulb that is most familiar to residential consumers and professionals alike.

Main Specifications:
•    Up to 40W & 60W Incandescent
•    Lumen Output : 450 - 480lm & 800 - 850lm
•    Power Consumption : 8W & 12W
•    Efficacy : 56 - 60lm/W & 67 - 71 lm/W

The Definity Professional A19 LED lamp achieves superior performance with up to 71lm/w and is easily dimmable down to 5%. Performance is achieved with a reduction in raw materials and an innovative heat sink design comprised of advanced CoolPoly® material resulting in superior thermal management with lighter weight.

Likewise, the Definity Professional GP19 LED lamp utilizes lightweight aluminum and cutting-edge design to optimize the performance and aesthetics. The GP19 LED lamp achieves ENERGY STAR equivalency performance comparable to a 40W lamp with the increased efficiency and life that can only be provided by LED technology. The GP19 Led lamp also tops 80 lm/w and is also down to 5%.

"Consumers have been asking the LED industry for bulbs which more closely replicate the form and function of a traditional Edison bulb," said Jeremy Cage, CEO of Lighting Science. "These new lamps represent that, and much more—they are highly efficient, emit a beautiful light, contain no mercury and are a strong LED value. These lamps make every room more beautiful with their lighting quality."

The new lamp line 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 residential homes and businesses.
