Hey guys! Recently getting around to moving into a new place and the kitchen sink light is out. It had one of those crappy electronic F20 ballasts and it's burnt up. I tried swapping in one of my magnetic dual F20 ballasts and it's just making the tubes flicker. So I guess that one is bad too. Even though when I put it away it was good  I'm wondering if anyone has a good one or two they'd be willing to part with. If not I can maybe find something at Lowe's. |

HID, LPS, and preheat fluorescents forever!!!!!!

| Are you looking for trigger start ballasts?
Additionally, tubes can start more reliably if you convert the fixture to preheat. One method of doing so is to use a single lamp F40T12 preheat ballast to run both tubes in series or use 2 individual F20T12 preheat ballasts.

| Rapid start or preheat. Doesn't matter to me. It's technically not my fixture (it's my father's). I just don't want to be forced to convert it to LED and I want it to last virtually forever. I'd also like to avoid the junk electronic ballasts if possible (that's what was in it in the first place).
The fixture is wayyy too small to fit an F40 ballast. It barely fits a magnetic F20 ballast and tubes. There is about 7mm of space between the tube and the ballast.
It's one of those compact wrap around things.

Stop replacing fixtures that can be retrofitted.
|
| I'll see if I have any. I have one in use currently, but I may have gotten a few spares from a ballast lot I won at auction.

Are you sure your lamps are good and the sockets aren't shunted? I have a few ballasts I'm not using, including one that's HPF. That one is nice and bright might not fit. The NPF ballasts are dim with F20s. I did the two preheat choke setup in this fixture. Another good option for keeping it fluorescent would be to get a decent name-brand F17/F32 electronic ballast and install F17T8 lamps. |

| I could try the preheat choke idea... I think they actually still sell those at Lowe's.. I'm not sure though.
Yeah that HPF ballast looks way too big unfortunately. I wish the existing fixture wasn't so puny but I don't have anything to replace it with and on top of that it is held in by those weird spider dry wall anchors that just sit inside the ceiling. So If I try to take it down I won't be able to get anything back up easily

| If you want to simply grab something from Lowes or the like, I'm pretty sure you're stuck with electronic. At least Lowes does carry GE electronic ballasts that'll operate F20T12, and of course they have F17T8 as well.

If you want ballasts that drive tubes at full power, here is one that you might find useful: https://www.ebay.com/itm/304723069390But in that case, you will need 2 of them. Here are some small single lamp 110V 60Hz and 120V 60Hz F40T12 preheat ballasts, I think they are smaller than a typical North American single lamp F40T12 preheat ballast: https://www.ebay.com/itm/166282314675https://www.ebay.com/itm/126004978786You could certainly use them for running a pair of F20T12 tubes in series. |
