Revised 1/6/19
TMC AquaRay has finally granted the AquaBeam NUV 410nm LED to be released to the US market. The LED was released to Europe back in 2013 and only to the UK, for quantity control issues. The LED has the same design as the rest of the Solid State AquaRay line, with 5 SemiLED x 410nm near-ultra violet (NUV) didoes, 120 beam angle. It has the waterproof rating of IP67, no fan, shimmer, low carbon output/watts, PWM dimming, and the 5 year full replacement warranty.
At this point of 2016, American Aquarium Products is the only full service authorized supplier of these LED to the Western hobbyist. The point of a emitter in this range is to enhance the colors of corals, fish, and plants.
TMC States:
“This 410nm wavelength will make corals fluoresce (as well as some other critters and fish) and has been shown to improve the red pigment ratio of certain deep water coral species such as Lobophyllia and Trachyphyllia“.
“The addition of this wavelength makes LED lighting look even closer to natural sunlight, truly the true to nature lighting solution you can buy!”

Since this lighting spectrum is in the far side of the lighting spectrum, which also dips into the UVB range, limited quantity/amounts of the light is suggested.
TMC rates on strip of 5 emitters to light up to 170gals/650 litres, and is best seen when the tank is extra dark, say at night, when daytime lighting is off. The LEDs can be used during day lighting hours, just the recommendations of one strip per 170gals has to be considered for true coloration and amounts of UVB provided.
There are other Ultra Violet LEDs out in other commercial fixtures to date, but nothing up to TMC standards of quality of build, and also as a stand alone fixture. Some marine fixtures do have a couple NUV emitters in their fixtures, but separate controllability is not an option, which is why a separate fixture is preferred.
TMC does not give a rating on how long to run the fixture, say all the way threw the night, so caution is advised for health in mind. Start slow and work your way up and also know, limit amounts of this lighting type (more to the UVB range) actually reach the Earth surface.

TMC NUV with Reef White Combo
Watch your eyes, as it can be quick to try and blind you. UVB is harmful, so consider safety.
The fixture could be considered for reptile use, but keep in mind, it has a purple/blue look and since this is a new technology, reptiles would really need to be watched as far as health, as no reptile UVB LEDs are on the market as of yet.

Standard UVB Fluorescent

NUV Spectrum
Considering the amount of energy used by both fixtures, the NUV could be used as a supplement UVB light, to be ran all day during normal daylight hours for reptiles. For reef tanks, volume of water needs to be considered. The supplement light can be ran all day on 170 gals of water.
