Update:
I had read some reviews on another site in which someone had a Grandrich light, and rather than sending the light back, the company sent them the ballast for it. (I'm not sure what a ballast is, but it sounds very electrical)
So, I called the company, and the guy didn't argue with me or anything, he's sending me the ballasts! They must have had quite a few go bad. My husband's extremely handy, but fine electrical work is not something he's done so he made a face, but I explained, we were going to toss them anyways, we have 3 here, lots to practice on!
(I've seen the Full Spectrum brand and the Daylight brand)
