Cree Demonstrates 131 Lumens per Watt White LED

DURHAM, NC, JUNE 20, 2006 ­ Cree, Inc. (Nasdaq: 
CREE), 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™ 
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.
