This result demonstrates Cree’s continued focus on pushing the performance of its LEDs. Cree’s tests confirmed that the LED produced 197 lumens of light output and achieved 186 lumens per watt efficacy at a correlated color temperature of 4577K. The tests were conducted under standard LED test conditions at a drive current of 350mA, at room temperature.

“This result is a testament to the tremendous progress Cree has made this year,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “As energy efficiency becomes increasingly important in addressing our nation’s energy challenges, Cree is doing its best to deliver the most energy-efficient LED technology possible.”

While this level of performance is not yet available in Cree’s production LEDs, Cree continues to offer volume quantities of the industry’s broadest family of 100+ lumen LEDs.
