I have a number of florescent shop lights that are of the hang and plug in type. The old ones with the T12 tubes still work fine. The newer T12 and the newest T8 fixtures will randomly trip the GFCI breaker. I have swapped out the breaker and it still trips, When I plug them into a GFCI recepticle the same thing happens. It's random, sometimes several times in a day then not for weeks and not always the same light being turned on. I have some CFL that do the same thing.
I have examined the fixtures for worn wires, and corroded contacts where the lamps plug in finding nothing that looks suspicious. They even pass the sniff test..The problem doesn't seem to follow the weather.
Is there a fundamental disharmony between florescent and GFCI? Just a sign of old age? The GFCI breakers are about 16 years old.
