Hey fellow growers, I have an 4 foot 8 bulb T5 grow light and one of the fixtures crapped out on me. Has anyone cracked one of these open? I'm guessing it has two 4 bulb ballasts but I'm really not sure. I suppose it's not that big of a deal but it bugs me. It's not even two years old, but I don't want to crack it open and cause more damage. You can turn the outer 4 on, the middle 4 on, or all of them on. Please advise...
