Got this to replace a burned out ballast for a two bulb under cabinet light using F8T5 bulbs. Pros: - Works as advertised - Functionally better than the previous ballast it replaces - With the old ballast no lamp will light if a bulb is out. Cons: - Bigger than the old ballast (but still fits in our under-cabinet bracket) so it'll probably light a good bulb even if another fails where the old ballast wouldn't light), so I had to take an extra outlet with me find twisted wire. (I'm not an electrician so I didn't have anything lying around.) - The mounting holes were different than the old ballast which required modifications to the bracket and I had to find new screws. (because it didn't exist) Overall it's cheaper than replacing the entire jig and seems to be working well so far. (It was in operation for about an hour.)
