SAN FRANCISCO—Claiming a breakthrough in light-emitting diode (LED) technology, Cree Inc. Tuesday (Feb. 7) announced a new product that the company claims delivers twice the lumens per dollar of conventional LEDs and offers the highest performance in the industry.
Based on a new silicon carbide technology platform, the Cree’s XT-E LED and the recently released XB-D LED addresses the largest obstacle to mass LED lighting adoption, initial cost, according to Cree (Durham, N.C.).
Cree maintains that the XT-E LED more than doubles the lumens per watt (LPW) of its 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 3.45mm x 3.45mm XP footprint and can be used for almost all lighting applications, according to Cree.
Because the XT-E White LED is a successor product to XP-E High Efficiency LED, customers who incorporate it into lighting systems require only 3,000 hours of XT–E LED LM-80 data to achieve Energy Star qualification, as opposed to the normal 6,000 hours, Cree said.
Mike Watson, Cree’s senior director marketing for LED components, said through a statement that Cree’s XB-D LED "changed the game," introducing 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," Watson said.
The XT-E White LED delivers up to 148 lumens and 148 LPW in cool white (6000 K) or up to 114 lumens and 114 LPW in warm white (3000 K), both at 350 mA, 85°C, according to Cree.
Samples of the product are available immediately and production volumes are available with standard lead times, Cree said.
More information about the XT-E White LED is available on Cree’s website.
