The new XLamp XM-L RGBW is an extension to Cree Inc.’s range of combined red, green, blue and white LED emitters. Packaged as a 5mm x 5mm square component, the XM-L RGBW is made up of four individually addressable LED chips that enable extensive colour mixing potential.
XM-L RGBW is 60% smaller than the previous MC-E RGBW, which allows for the design of more compact light sources with greater optical control and more effective colour mixing.
In terms of light output the XM-L LEDs deliver up to 89 lumens for royal blue, 214 lumens for green, 229 lumens for red and 272 lumens for white at 1000mA.
