Cree claims 45% higher Lumen density for its Metal COB LEDs

Cree has expanded its XLamp High Current LED Array family with new metal-based chip-on-board (COB) CMT LEDs. In addition to providing up to 45 percent more lumen density and up to 17 percent higher efficacy, all Cree XLamp High Current LED Arrays feature an innovative metal substrate technology that delivers higher reliability than competing metal COBs, claims the manufacturer. With more than 6,000 hours of LM-80 data available, the expanded family of LEDs enables lighting manufacturers to immediately upgrade their designs for DesignLights Consortium and Energy Star eligible applications, such as track, downlight and outdoor lighting.
