Cree breaks through LED efficacy barrier at 303LPW

Cree Inc. has been said to push the boundaries of LED performance as the first company to surpass the 300LPW efficacy barrier.

With its white, high-power LED, the company achieved 303LPW efficacy at a correlated colour temperature of 5150K and 350mA using a standard room temperature.

This landmark result tops Cree's previous R&D achievement of 276LPW about a year ago.

"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 ('re'?), University of California, Santa Barbara.

"Relentless innovation is a driving force at Cree as we continue the pursuit of 100 per cent 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," added Edmond.
