Cree Sets R&D Record with 254 lm/W LED

Cree, Inc. delivered an industry first April 12, 2012 with a barrier-breaking 254 lumen-per-watt white R&D power LED. This significant milestone exceeds Cree’s previous R&D industry record of 231 lumens per watt and demonstrates Cree’s continued commitment to accelerate the adoption of LED lighting.

Elements of Cree’s innovative SC³ Technology Platform, available today in Cree XLampLEDs, enabled this record-breaking R&D result. The SC³ Technology Platform is built upon advanced silicon carbide technology, plus advancements in LED chip architecture and phosphors.

Cree reports that the LED efficacy was measured at 254 lumens per watt, at a correlated color temperature of 4408 K. Standard room-temperature, 350 mA testing, was used.

“The latest innovation from our R&D labs is another game-changer for the industry,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “The core of the Cree R&D culture is a relentless focus on innovation that ultimately drives LED adoption. Higher-performance LEDs can enable new and better LED-based applications and drive down the solution cost of LED designs.”

Cree is a market-leading innovator of lighting-class LEDs, LED lighting, and semiconductor products for power and radio frequency (RF) applications. Cree’s product families include LED fixtures and bulbs, blue and green LED chips, high-brightness LEDs, lighting-class power LEDs, power-switching devices, and RF devices.
