With a new range of multi-color LEDs, Cree addresses a wider spectrum of applications such as architectural, vehicle and display lighting. The company also introduces a new discrete LED platform which offers twice the performance in terms of lumens-per-dollar than earlier models.

Cree XLamp XB-D color LEDs extend the double lumens-per-dollar performance of the XB package to color LEDs, delivering up to 40 percent higher maximum light output than XP-E color LEDs. The combination of performance and the small size of XB-D color LEDs enable better color mixing and lower system cost through fewer LEDs. Now available in color as well as existing white color temperatures ranging from 2700 K to 6200 K, customers can support a full range of color in the single XB footprint.

Cree XLamp XM-L color LEDs are the brightest and smallest multi-colored LED of their power class, delivering red, green, royal blue and white in one LED at twice the lumens-per-dollar of the MC-E color LED. The XM-L color LED is 60 percent smaller than the MC-E LED, reducing the distance between LED die, to create a small optical source for excellent optical control, efficient color mixing and simplified design.

XLamp XB-D color LEDs deliver up to 1416 mW for royal blue, 92 lumens for blue, 198 lumens for green, 210 lumens for red and 261 lumens for red-orange, all at 1A in the 2.45 mm x 2.45 mm footprint.

XLamp XM-L color LEDs deliver up to 89 lumens for royal blue, 214 lumens for green, 229 lumens for red and 272 lumens for white at 1A in the 5 mm x 5 mm footprint.

Cree XLamp XB-D and XM-L color LED samples are available now, and production quantities are available with standard lead times.

This is highly misleading, and is due to the poor sensitivity of the eye to blue.
The green LED emits about 210/627W - 1/3 of a watt - with 3W in - so 10% efficient. Blue is around 50%.
