I have them. I don't like the 10K/RB mix color. 10K is too high IMHO. Makes the tank/rocks look sterile. I added deep red and green from Satis, but perhaps too much red. Re-doing these lights takes forever. Waiting on some neutral whites from led group buy. I don't have their drivers. I used Inventronics so I can control dimming with reef keeper. In terms of corals I have various zoas that do fine, frog spawn, recovering long tentacle plate, orange monti, unknown SPS frag - all do fine. I have some green palys that do not like these leds it seems. They were happy under my old MH/PCs now they close up when the white lights come on too high. Have the PAR meter sensor that I need to set up so I can read PAR. Maybe this weekend.
