Cree announced the white power LED luminous efficiency achieves 303 lm/W, establishes a new milestone in the LED industry. This research results exceed the industry record (276 lm/W) that was set more than one year ago and much earlier than originally anticipated.
Steven DenBaars, professor and co-director, Solid State Lighting and Energy Center, UCSB, said “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.” Cree report shows that under the conditions of color temperature 5,150 K and 350 mA drive current, the measured LED luminous efficiency is 303 lm/W, and the testing was conducted under standard room temperature.
John Edmond, Cree co-founder and director of advanced optoelectronics said “Relentless innovation is a driving force at Cree as we continue the pursuit of 100-percent LED adoption,” he also added “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.”
