Is ATI the only one you are looking for?
I have Nova extreme pro 6 x 39w t-5 fixture. It's got dual power cords, for dusk and dawn effect, dual cooling fans and the reflectors are individualy curved for each bulb.
Im the second owner, got it used two years ago. Bulbs are a year old, so you would have to change them. Let me know if you are interested.
