CREE XT-E Royal Blue

**UPDATE** In stock and ready to ship The XT-E is the replacement technology for the CREE XP-E using Cree's new silicon carbide wafers. They deliver more flux using less power. These are the base LEDs used in aquarium lighting as the blue light, adding in other colors to supplement if necessary. We only stock bin Q04, the highest flux bin, and a 5nm wavelength distribution. These are the highest output and highest quality XT-E that can be purchased at this time.
