XLamp® XM-L® colour (RGBW) Gen 2 LEDs Cree LED XLamp® XM-L® colour (RGBW) Gen 2 LEDs are multi-colour (Red, Green, Blue, White) LEDs that offer a high lumen output and colour mixing in a compact 5mm x 5mm package. The XM-L Colour Gen 2 LEDs eliminate the space between the LED die to create a small optical source for excellent optical control and efficient colour mixing. Gen 2 also includes a high-intensity version that further reduces the optical source size for even greater levels of optical control. Cree LED XLamp® XM-L colour (RGBW) Gen 2 LEDs are optimised for all high-performance RGBW lighting applications, including colour-changing, stage, architectural and entertainment.
