One of the better spectrums I speak of, is the Mammoth Emerald Green/Mint White LED. 2537umol-880w.
Its got a 4800k-5000k rating. 2537umol-2.95 Efficiency. 3456 Diodes.
And still.
The Hortilux Blue goes from 280nm-2000nm+. I myself also add in 2 Solacure UVA/B Flower Power bulbs, in each 4 x 4 area, and 1000w HID., or equivalent. Those are most powerful from 280nm-300nm. But the UVA, is the same as the sun. In uvb, they are 4+ times more powerful which allows to run less lights, and less time for them to be under the UVA/B.
