**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.

This reef tank lighting gives you the light you need at a price you can afford. These lights use less energy, so you end up paying for less energy. These lights make my tank look awesome.

Built a system for a planted tank over a year ago and realized the cool white didn't bring out the color I wanted. Went with neutral white this time around and discovered I missed the crispy sparkle that royal blues provide. It's a fine line keeping a fresh water tank looking right though. These latest royal blues are so efficient, I was a bit surprised by how much stronger they were over the old CREE model (XRE I believe). I eventually found the best balance for freshwater to be a pairing of 1 XM-L neutral @ 1.7amps to 1 XT-E royal blue @ 350miliamps. I also added 4 OCW to the 350mA string over this 90 gallon tank for near perfection. Won't stop me from continuing to experiment though!
