most salt water light fixtures will work with a 10 gal set up, due to the fact it is small, and you are probably only going to have soft type coral in a tank that small. if you try to have stoney coral, and a very intense light source for the stony coral, in a 10 gal tank, you are going to be adding water like crazy. and if you are new to the hobbie, throwing several hundred dollars worth of stony frags in a ten gal tank, and having less that satisfactory results would drive most people to give up. small tanks require a little more research, don't overstock it for best results. choose hardy bullet proof soft coral, 1 or 2 species, maybe a few zoas, mushrooms, paly's, etc. then you can run a of the shelf fixture, with a two bulb, t-5 0ne antinic, and 1 6500k bulbs. just my opinion, and welcome to the most addiction hobby on earth.
