Cree’s new XLamp XT-E white LED doubles lm/W of XP-E
Cree Inc of Durham, NC, USA has launched the XLamp XT-E white LED, which is claimed to deliver twice the lumens-per-dollar of other LEDs and feature the highest performance and efficacy in the industry.
Based on a new silicon carbide (SiC) technology platform, the XT-E – as well as the XB-D (launched in mid-January) - represent what is claimed to be a transformation in LED price-performance.
The new platform addresses the largest obstacle to mass LED lighting adoption - initial cost - and enables LED lighting systems to replace their inefficient ancestors, Cree adds.
“The XLamp XT-E LED has exceeded our expectations,” comments Fritz Morgan, chief product officer of Digital Lumens Inc. “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,” he adds. “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 delivers luminous flux of up to 148lm and luminous efficacy of 148lm/W in cool white (6000K) or up to 114lm and 114lm/W in warm white (3000K), both at a drive current of 350mA and a junction temperature of 85°C. At 25°C, the XT-E delivers up to 162lm/W in cool white. This more than doubles the lumens per watt of the XLamp XP-E LED family, allowing use for almost all lighting applications.
Also, by leveraging the popular 3.45mm x 3.45mm XP footprint, users can easily incorporate the XT-E in existing XP LED designs to shorten the LED fixture design cycle and improve customer time-to-market.
Since the XT-E white LED is a successor to the 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.
“With the XB-D LED, Cree changed the game and introduced a better price-performance curve,” claims Mike Watson, Cree’s senior director marketing, LED components. “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.”
