Cree Continues to Push the Boundaries of LED Performance by Breaking 300 Lumens-Per-Watt Barrier

Cree, Inc. records another significant LED milestone with the demonstration of 303 lumens per watt from a white high power LED. Reaching the landmark achievement much faster than previously believed possible, this result surpasses Cree’s previous R&D industry best of 276 lumens per watt announced just over a year ago.

“This is truly an impressive accomplishment. Achieving this level of LED efficacy amplifies the potential for the solid-state lighting industry to deliver smaller, lower-cost lighting solutions, and even larger-than-expected energy savings,” said Steven DenBaars, professor and co-director, Solid State Lighting and Energy Center, University of California, Santa Barbara.

Cree reports that the LED efficacy was measured at 303 lumens per watt, at a correlated color temperature of 5150K and 350 mA. Standard room temperature was used to achieve the results.

“Relentless innovation is a driving force at Cree as we continue the pursuit of 100 percent LED adoption,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “Pushing the boundaries of LED performance is critical to enhancing LED lighting designs and this 303 lumens-per-watt result will enable more cost-effective lighting solutions.”
