How tall is the tank? I think everyone on here knows by now that I am a big spporter of T5 lighting and Sunlight Supply makes a good 24" fixture. If the tank is rather short, you could go with a 24" PC filxture. Current USA makes a Satellite and an Orbit fixture which are both tried-and-true fixtures that will work well.
If you could supply me with the height of the tank and a detailed list of corals that you want to keep I can give you a more personal recommendation.
