The Cree Royal Blue XT-E LED is a specially designed diode from Cree which delivers a very strong output of blue light at 445-465 nm and optimized for use in remote phosphor LED applications. Remote phosphor LEDs are those which have a coating of phosphors somewhat removed from the LED light itself, all white LEDs are a local phosphor design very much like fluorescent lamps have an outer coating of phosphor to produce white light of various colors. The new Royal Blue XT-E LED from Cree will be better able to produce white light by exciting phosphors in a remote design. Not only does the XLamp XT-E Royal Blue have exceptional output of 575-600mW at 350mA. Our binned spectrum of 445-455nm is great for both Photosynthesis and Colour Pop. We highly recommend this LED and its included in our top of the line Phoenix Kits as well our own ReefLEDLights line of Fixtures. If you want to grow coral this LED is your primary.

For the Marine Aquarium we recommend a 2:1 primary mix of Royal Blue with our Premium XT-E Cool White.
