so the other day I was going through Qs for our show, and noticed this fluorescent light acting weird, sometimes it works but sometimes it doesn’t. Now we did work on this last year because it wasn’t working, so we replaced the ballast and the light last year which in my opinion I don’t think it could have gone out that fast. Could it possibly be a short? Ever since our school had a renovation in 2009 this light fixture has been giving us problems. Any clue on what it could possibly be?
