what kind of fixture are you looking for? I have an old hood with 4 T5s powered by an icecap 660. It was on top of one of my first 90 setups.
The hood is kinda crappy, but should work, I think its stocked with 2 10ks, and 2 actinic bulbs, 4months run time..
I got it from the previous owner, who looked like he slapped it together.. but you are more than welcome to it if you are in need.. its just collecting dust in my basement..
