The Reef White NP Ultima is an over all deeper penetrating 20K reef aquarium light, which consists of (4) 10,000K extremely high output NEW patented Ocean White XT-E LED, (2) "Fiji Blue" XT-E LEDS (deep blue), and (4) NEW "patent pending" NP full spectrum Blue ("Nature Perfect" from Osram Oslon) LED emitters. These have two different channels. Daylight can be controlled separately from the NP Blue emitters (with the use of a controller or unplugging one lead). Unique individually focused/lensed 60 degree beam angle emitters for MORE DEPTH penetration.
The overall color balance of the "Reef White Ultima". When fully on, it replaces a 20,000K light. It is ideal for a deeper penetrating light in a marine reef aquarium up to 30 inches in specimen placement. Uses the newest generation patented XT-E emitter by CREE (NOT an off the shelf XT-E emitter) as well as patent pending Osram Oslon NP emitters, with the first unique "FULL SPECTRUM" blue emitter specifically designed for photosynthetic marine life! More about the patented Nature Prefect Emitter: Amazing technology, where what we see with our eye and what light energy being provided to the tank are different from each other.
It would be hard to give a peak wavelength for this emitter as it is not a narrow bandwidth. This LED has a little phosphor on there to enable it to emit light across the whole visible spectrum. Its spectrum actually looks this (the dotted line is the human eye response curve). So, not only a more natural looking moonlight, but also a more natural overall spectrum, while providing a great action spectrum. 08 µMolm²sec per input watt on a watt per watt of energy consumed comparison (twice as efficient as the Radion Pro, and 3 times that of many such as the Kessil) The Reef-White Ultima 2000 IS STILL THE PREMIER REEF LED for PUR light output per watt of energy used.
Despite the non-scientific hype coming from some & compares to up to a 250 Watt Metal Halide in useful light energy.
