Scott270, correct me if i am wrong, are you looking for a lighting system (fixture) that just sits on top of your 75g glass tank? I apologize for early post about the price on ----, i didn't realize it's a fixture, thought is a retro unit. but again i think most item on ---- starts low $, this guy starts high. But after i did some search, that system isn't too bad for a fixture, i personally prefer custom sealife.
i hope it's not against swf.com rule, but Jalli makes some economical pc fixture, i found it, item# lt-JLCFS55W48 at customaquatic.com at a good price too. Also if you are not in hurry to upgrade light, ---- has a seller tbbygirls often sell great reef products, she just sold a few ice cap ballast for vho, and currently selling 4 new vho now at $15. again hope i aint violating any rule. Good luck in finding your light.
