SiC makes LED performance better and pricing easier
Cree's new silicon carbide device platform is claimed to deliver twice the lumens-per-dollar of other LEDs and feature the highest performance and efficacy in the industry
Cree says it has made a breakthrough in LED technology that completely redefines the lighting industry and erases old assumptions about up-front LED cost and performance.
Based on the new SiC technology platform, the XT-E LED and the recently released XB-D LED represent a dramatic transformation in LED price-performance. Cree’s new platform addresses the largest obstacle to mass LED lighting adoption, initial cost, and enables LED lighting systems to replace their inefficient ancestors.

“Cree has a history of delivering excellent LED solutions and the XLamp XT-E LED has exceeded our expectations,” said Fritz Morgan, chief product officer, Digital Lumens. “We are committed to building the most energy-efficient industrial lighting systems and the XT-E LED enables us to do just that with high lumens per watt. The result is an intelligent LED-based lighting system that is driving widespread adoption of LEDs in industrial facilities, with compelling performance and end-user payback.”
The XT-E LED more than doubles the lumens per watt of the XLamp XP-E LED family – providing up to 148 LPW at 85°C (or up to 162 LPW at 25°C) at 350mA. The XT-E LED delivers exceptional performance in the popular 3.45mm x 3.45mm XP footprint and can be used for almost all lighting applications.
By leveraging the XP footprint, customers can easily incorporate the XT-E LED in existing XP LED designs to shorten the LED fixture design cycle and improve customer time-to-market. Additionally, since the XT-E White LED is a successor product to XP-E High Efficiency LED, the application for ENERGY STAR qualification requires only 3000 hours of XT–E LED LM-80 data, instead of the normal 6000 hours.
“Our mission is to drive the LED lighting revolution through our relentless pursuit of innovation and by helping manufacturers bring high-quality, affordable LED lighting to market,” said Mike Watson, Cree senior director marketing, LED components. “With the XB-D LED, Cree changed the game and introduced a better price-performance curve. Now, with the XT-E LED, Cree continues to break barriers and extend its leadership on this new trajectory, delivering products that accelerate LED adoption.”
Cree says the XT-E White LED delivers up to 148 lumens and 148 lumens per watt in cool white (6000 K) or up to 114 lumens and 114 lumens per watt in warm white (3000 K), both at 350 mA, 85°C.
Samples are available immediately and production volumes are available with standard lead times.
