Cree Achieves 186 Lumens per Watt from a High-Power LED

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.
