I'm waiting for my T12s(kitchen has 3 of the 2 lamp fixtures) to burn out but when I bought the house it came with a 2 pack unopened in the basement and I've only had one bulb have a sketchy start. It would be nice to have more efficient ballasts that don't buzz. If I go this route, I'll hang on to the mag ballasts(after finding out which one is quietest and marking it), in case they have a short life. Thank you.
