I'm a noob.. what is this part on my fixture?


I know that I definitely need new bulbs.. they are flourescents NO I believe you call them

Anyway on the fixture there is a cylinder.. thing that I thought was a turn nob until I pulled on it and it came out. It has 2 metal type things on it.. and I just pushed it back in and the fixture works fine.

What is this? some kind of backup battery or something?

It is the ballast that fires up your bulb.

Sorry to get technical Tank Girl, but I believe what Wavetide is talking about is actually the starter. Ballasts are much larger and heavier. Also They were used on older, and cheaper (sorry WaveTide) fluorescent fixtures. If your fixture is the type where you have to press a button until the bulbs start to glow it has no ballast, and that piece is the starter. What a starter does is does is it builds up an electric charge to ignite the neon gass in the tubes. In addition to pushing it back in it should also turn about 1/8 turn to lock it in place.

You are so right! I totally misspoke - the ballast is the heavy box-like part on some fixtures. The starter does fire up the bulb, though....
