I had the K7s as close to the water as they could be and were at full intensity. What PAR numbers were you seeing? I'm reviewing a paper now that suggests PAR of 100 is OK for some Acros.I find that interesting because I just pulled my K7 off a 20 long because cranked to max it doesn't have enough PAR for Acropora. Well, barely it does, but not at a good color. My Mars Aqua crushes my K7 in terms of PAR and color with the only advantage is the Noop has better shimmer. Mars aqua is also a lot cheaper.
The Noop is a cool light in concept but it had some glaring issues. The biggest problem is it doesn't have enough royal blue and too many white LEDs and too many cool blue LEDs (Windex looking blue vs deep blue).
So, to get enough intensity you have to crank the white and cool blue channels, which makes corals look really brown and green. Kind of like how cheap, knock off 14k halides used to look, or the first gen Kessils. Everything is kind of monochrome and brown. Corals don't care, and neither do fish, but if you like a lot of rich color in your tank you will hate the Noop at high intensities. Sad thing is they can fix this easily,
