DURHAM, N.C., June 20 /PRNewswire-FirstCall/ -- Cree, Inc. , a market leader in LED solid-state lighting components, today announced LED efficacy test results that set a new benchmark for the LED industry. Cree reported results of 131 lumens per watt white LED efficacy, confirmed by the National Institute of Standards and Technology in Gaithersburg, Maryland. Tests were performed using prototype white LEDs with Cree EZBright(TM) LED chips operating at 20 mA and a correlated color temperature of 6027 K.
"This is the highest level of efficacy that has been publicly reported for a white LED and raises the bar for the LED industry," said Scott Schwab, Cree general manager, LED chips. "This result once again demonstrates Cree's leadership in LED technology and provides a glimpse into the future as to why we believe LED-based lighting products could not only save energy, but also change the way people use light."
"Technical advancements at the component level are critical to growing the emerging white LED lighting space. Cree's results speak to the exciting developments underway that will enable new white light applications and subsequently facilitate market adoption," stated Fritz Morgan, chief technology officer for Color Kinetics, a leading innovator of LED lighting systems and technologies.
Lumens-per-watt is the standard used by the lighting industry to measure the conversion of electrical energy to light. As a reference, conventional incandescent light bulbs are typically in the 10 to 20 lumens per watt range, while compact fluorescent lamps range from 50 to 60 lumens per watt.
