Used as the main blue source for display tanks. This is a very "actinic" and mixes well with Neutral Whites to give the look needed for most display reef aquariums. Often you want to use 66% Royal Blue and 33% Neutral white to get a 14k look.
XT-E Royal Blue is more efficient than the XP-E series delievering approx 20% more light for 12% less energy savings you money on energy bills and number of LEDs needed.
The version of the Royal Blue we carry out performs any other Royal Blue on the market including the Luxeon Rebels. We provide only the Q04 group that provides over 1600mW of power.
The 450nm-455nm XT-E Royal Blue which is the perfect wavelength for color/growth of LEDs. Wider, less accurate wavelength LEDs that range over 20-25nm are not grouped with our LEDs. We also do not carry anything under 450nm because of the sharp decline of coral photosynthesis under 450nm.

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!
