I can't see how that is the case. The A360 has UV built in and I can't run it over 75% without nuking everything in my tank. This argument is an old one to be honest. LED can grow the same as any other light out there. You may not like the color but that's a personal preference built on the ability to pick bulb combinations with t5 or temperature with MH.I've never owned either, but everything I've read from hobbyists say that kessil doesn't support sps growth enough for the price tag. Have you checked Mike Herman for pricing on his sb line of black boxes. Custom layout, and spec, true uv, and at a fraction of the price of either. I just ordered myself one.
