LEDs performance reaches new high

Unlike traditional LED solutions that diffuse optical sources to deliver hundreds of lumens, XM-L LEDs are designed to provide 'breakthrough' performance in a small optical source size. Cree claims the high lumen density can simplify designs and reduce costs for lighting manufacturers building products for directional lighting applications, such as high bay, parking, roadway, track, spot and LED replacement lamps. The XLamp XM-L LEDs are designed for a range of indoor and outdoor lighting applications and, according to Cree, deliver 'unmatched performance' across a number of drive currents. Warm white (3000K) XLamp XM-L LEDs provide up to 113 and 117lumens per watt and neutral white (4000K) XM-L LEDs provide up to 134 and 138 lumens per watt, both at 350mA. At 700mA, warm white (3000K) XLamp XM-L LEDs provide up to 220 and 108lumens per watt and neutral white (4000K) XM-L LEDs provide up to 260 and 128lumens per watt. Driven at 3.0 A, XM-L neutral white LEDs produce 850 lumens at 84 lumens per watt. "Cree is the only LED manufacturer currently delivering production volumes of warm and neutral white LEDs at these performance levels," said Paul Thieken, Cree, director of marketing, LED Components. "Cree innovation translates into ready to ship components that can enable our customers to develop highly efficient LED fixtures from streetlights to downlights and from desk lamps to A-lamps."
