Cree Sets New R&D Performance Record with 254 Lumen-Per-Watt Power LED

Extends Leadership with Unveiling of Highest Efficacy Power LED
DURHAM, N.C. --

LED lighting leader Cree, Inc. (Nasdaq: CREE), delivers another industry first 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 XLamp® LEDs, enable this record-breaking R&D result. The SC³ Technology Platform is built upon Cree’s advanced silicon carbide technology, features advancements in LED chip architecture and phosphor, and boasts a new package design to deliver the most advanced LED components in the industry.

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 to achieve the results.

“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.”
