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.”

Samples are available immediately and production volumes are available with standard lead times.
