Powered by Cree’s groundbreaking SC5 Technology™ Platform, the XLamp XHP70 LED is a member of Cree’s Extreme High Power (XHP) class of LEDs that redefines lumen density and reliability to radically reduce system costs by up to 40 percent. At its maximum current, the XHP70 LED delivers twice the light output of the industry’s brightest single-die LED, the XLamp MK-R LED, at a similar lumens per watt and without increasing the package footprint. The XHP70 LED also achieves longer lifetime at higher operating temperatures. The overall result is significantly lower thermal, mechanical and optical costs at the system level.
These copper core PCBs significantly boost the performance of LEDs. The direct thermal path technology makes it possible to drive the emitter much harder than factory specification. The emitter is soldered DIRECTLY to the copper heat pad. . These are high quality, and preform well above standard aluminum MCPCBs. Boards that simply use copper for the base and retain use of the crystal substrate layer in the center will not give you the same performance.Using these stars in combination with PROPER heat sinking emitters can be driven to significantly higher than rated capacity. Output Gains are seen even at DOUBLE the rated drive current of emitters. Output increases are also achieved at some standard currents.
