Cree, Inc. reports another industry-best efficacy record of 231 lumens per watt for a white power LED. This result is a significant advance beyond Cree’s previous industry record and further demonstrates how Cree’s relentless innovation continues to push the boundaries of what is possible with LED lighting.
Cree reports that the LED efficacy was measured at 231 lumens per watt using a single-die component at a correlated colour temperature of 4500 K. Standard room temperature 350 mA testing was used to achieve the results.
This R&D result features advanced aspects of the same technology used in Cree XLamp white LEDs. Cree believes higher-performance LEDs can enable new LED-based applications and drive down the solution cost of current LED-based designs.
