can I retro this?

[jmack]

I have the regular Orbit PC fixture...I'm wondering if I could install T5 HO retros in this hood...if so, how would it affect the operation of the unit?

If you can gut it out and fit the T5 reflector in there I don't see why you can't do that. I don't know how wide is that fixture but PC fixtures generally aren't wide enough to jam in a significant number of tubes, but I guess it would be ok if it is just for supplementary light.
