The XLamp XP-E2 Cree (Distribution: MSC sales) requires a total of fewer LEDs to achieve comparable brightness values. So that the LEDs have a high luminous leucos efficacy in lumens per watt and improved efficiency in lumens per euro. With the LED above all the system cost: For developers, this means that they can bring high-quality lighting systems on the market with the XLamp XP-E2, having to perform without any major changes to the basic design of the lights. The XLamp XP-E2-emitting diodes have with 3.45 mm x 3.45 mm, the same degree as other models of the XP-series, including the XLamp XP-E and XP-G, which is also manufactured by Cree. In addition, the LED lights have similar optical properties. The LED is suitable for a wide range of applications where high lumen values are in demand - from lighting systems for indoor and outdoor use on portable lamp to retrofit leucos lamps. The basis is the SC LED technology leucos in the development of the XLamp XP-E2 Cree went back to his SC LED technology platform. The LEDs achieve a light output in lumens per watt up to 128 lm at a drive current of 350 W measured at a temperature of 85 C when a color temperature from cool white (6000 K) is required. At 25 C 143 lm / W can be achieved also with a current of 350 mA and a color temperature of 6000 K. The SC platform combines the silicon carbide technology enhancements in the LED chip architecture and phosphor technology and a novel approach to the design of the housing. Shortened leucos LM-80 qualification
These include specifications, performance, and LM-80 test reports. Since the XLamp XP-E2 is a successor of the XP-E LEDs, the LM-80-Qualification of lights with XP-E2 LEDs from 6000 to 3000 hours shortened. leucos Available are versions with a color temperature of 2700 and 7000 K and CRI values of 70, 80, 85 and 90
