Here are 4 of mine mounted. I am waiting on another T Slot wall mount to mount another row of 2 lights. They are mounted 9" above the water line and will probably raise them an inch or two when I remount them.
Love these new lights and boy are they powerful. You need to watch the 400 & 420nm as they do not add alot of "brightness" but add tons of Par. I dialed them in with my Apogee MQ-510. When I dialed them in by eye I was hitting 600 par on the sandbed in the middle of the tank..
Not sure what else you would want from a light, huge room to play with colors because of the power output, no...absolutley no Disco on the sand, dead silent, no glare, many mounting options with T Channel and no crappy app to control them, ect.
Those of us that got in at the pre-production promo got a steal.
