Not that this was something I was thinking of doing this soon, since I haven't even had my current MH light for 1 year yet, but one of the ballast for the T-5's must have burnt out. So when the MH light is not on I lost half my lighting. I doubt I will go back to MH. The thing just burnt so hot. So I am looking for something middle of the road, not cheap and not to expensive. This will go on the 72 bow front. Looking in to suggestions from you guys.
