I love it. You can see I had sps to the edges of the tank and they were getting plenty of light. I don't know your tank/coral goals but I think you'd be able to grow anything even in a 36" tank.
It is the 250w MH w/ the RB led strips and I really couldn't be happier. I wanted a "set it and forget it" light fixture and that's what I got. You can't go wrong, IMO.
Unfortunately, I can't comment long term on sps growth/health as I mostly had frags for several months until AEFW kind of wiped them out. But, they were doing fantastic up until then for several months. Now, since I'm in the re-building phase regarding corals, I'm upgrading to a 150g 5' tank. I picked up a second 15" fixture from BRS for it and have zero concerns it will be adequate.
