I really like the light actually. It comes with a splash shield AND has active cooling. Which IMO is a BIG plus. It will allow the bulbs to burn at cooler temps and thus extend the life of the bulbs a bit longer. The only down fall is the contoured reflector, which is not true individual reflectors, instead just one shield bent around each bulb.
IMO, this light puts out PLENTY of light for a tank 24'' and shallower. I run the 36'' 6x39w on my 50 breeder. I grow SPS very well in my setup. I also house a healthy BTA as well.
I ran the 48'' 6x54w on my old 75g tank, all corals did very well under that light too.
HTH,
