White power LED achieves 200 lumen per watt

Cree, Inc. announces another industry-best reported efficacy record of 208 lumens per watt for a white power LED. Cree’s tests confirmed that the LED produced 208 lumens of light output and achieved 208 lumens per watt efficacy at a correlated color temperature of 4579 K. The tests were conducted under standard LED test conditions at a drive current of 350 mA at room temperature.

While this level of performance is not yet available in Cree’s production LEDs, the company claims to continue to lead the industry with the broadest family of high-performance LEDs.

Cree’s product families include recessed LED down lights, blue and green LED chips, high-brightness LEDs, lighting-class power LEDs, power-switching devices and radio-frequency/wireless devices. Cree solutions are driving improvements in applications such as general illumination, electronic signs and signals, variable-speed motors, and wireless communications.
