Now find your Cree XLamp XP-E2 LEDs in a variety of colors. The XP-E2 uses Crees SC3 (silicon-carbide) technology to boost output over the original XP-E diode. This performance boost makes the XP-E2s color output 88% brighter than alternative high-power color LEDs. Now lighting manufacturers are able to design for a wider range of applications more cost effectively. These XP-E2 color LEDs can be seen in architectural, vehicle and display lighting. Both versions (1-Up & 3-Up) of the color XP-E2 are designed to work with secondary optics from Carclo; Carclo is a leader in molded poly-carbonate lens systems. The 1-Up secondary lens system combines a plastic holder and lens that sits on top of the 1-Up MCPCB, while the 3-Up optic is a one-piece system with three legs that sit down into corresponding holes on the 3-Up MCPCB. These secondary optics focus light into narrow, medium, wide and elliptical patterns. More information is available on optics that mate with the XP-E2 LED on this page under the Accessories tab above.
