gibbin94 and Mike, thank you.
I visited my lfs
yesturday and spoke with a gentleman that showed me a t5ho which I will be buying probably today. I honestly don't remember the brand or wattage (not that I understand the wattage at all. I just know from reading that I need 4 to 8 watts per gallon, lol) I know they were 48in bulbs and had four bulbs, 2 white, 2 blue... all in the same casing. Very bright when he lifted it to show me what it looked like.
Mike, what do you mean about each having their own reflectors? I think each bulb was in its own rail with its own backing, is that what you mean? I will make sure when I go back to ask.
