Cree claims industry’s brightest single-die LED

December 13, 2012 // By Christoph Hammerschmidt
A performance milestone claims LED manufacturer Cree with the commercial availability of XLamp XM-L2 LEDs. The LED delivers up to 186 lumens-per-watt at 350 mA, 25°C, a level of performance available only in a lab setting just three years prior.

Built on Cree's proprietary SC³ Technology next-generation LED platform, the new XM-L2 LEDs double the lumens-per-dollar and deliver 20 percent more lumens-per-watt over the original XM-L LED – enabling lighting manufacturers to use fewer LEDs to deliver a lighting system for lower cost.

The XM-L2 LED is designed for very-high-lumen applications in the segments of indoor, high-bay and outdoor lighting. The XM-L2 is compatible with existing XM-L LED designs and leverage the 5 mm x 5 mm XM footprint – allowing customers to incorporate the XM-L2 LEDs into existing XM LED designs.

The XM-L2 LED offers the combination of very high efficacy and high drive currents, delivering remarkable1198 lumens at 116 lumens-per-watt efficacy at a current of 3A and an ambient temperature of 25°C. The XM-L2 is the eighth product built on Cree’s SC³ Technology platform which leverages Cree’s silicon-carbide technology, features advancements in LED chip architecture and phosphor and offers a new package design.

Characterized at 85°C, the XM-L2 LED is available in 2700K to 6200K color temperatures and offers minimum CRI options of 80, 85 and 90. Additionally, since the XM-L2 LED is a successor product to XM-L LEDs, the application of ENERGY STAR qualification requires only 3000 hours of XM-L2 LED LM-80 data, instead of the normal 6000 hours. The XM-L2 LED is also UL-recognized and features a level-4 rating.
