Cree pushes through 300-LPW LED efficacy barrier
March 27, 2014 // Paul Buckley
Cree, Inc. claims it is the first company to break 300-LPW LED efficacy barrier by demonstrating a white, high-power LED with a LED efficacy measured at 303 lumens per watt, at a correlated color temperature of 5150 K and 350 mA.
Standard room temperature was used to achieve the results. The landmark result surpasses Cree’s previous R&D industry-best of 276 lumens per watt that was achieved about 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.
“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.”
