I think I may be confused on now, is that light fixture from Lights of America that everyone seems to be using on there refugium a halogen bulb or flourescent?
I went to their web site and all I found was the flourescent bulb stuff.
It would actually be a high output compact flouresent more commonly referred to as a "power compact" by most in the hobby. The 65W version everyone raves about is a 6500K color temp. and really a decent light for the $ IMO.
