Go to home depot and pick up, i think, its a 45w or 65w 2700k cfl. BIG fucker. If not, set up like 4 or 5 23w cfl om top. How tall is that case? You could also get an old computer power suply and run an unlimited amount of fans off that. I am running two for exhaust amd one for circualtion with passive intake and my temps are perfect. Just a thought,
