Hope one of you electricians can help me. We moved into our new home recently. The garage has 2 flourescent light fixtures with STR ballasts. When they are turned on they “sing” to our FM radios throughout the house. The guy who wired the place checked out his wiring etc. and could not explain a cure. He is a licensed electrician. HELP !!!
Thanks

How far are the radios from the switches? Are they plugged into the same circuit as the lights?
Dunno where you live, but anywhere where the garage temp is apt to dip below about 30F fluorescent fixtures should have electronic ballasts. I can't tell what "STR" designates.
I can't tell from your description whether the noise is classical fluorescent hash (an annoying buzz) or electronic interference (a relatively "muscial note" of sorts). If it's hash, change out the fixtures (or the ballasts) for electronic. If it's electronic interference you probably have electronic ballasts already and either need better ones or need to correct a problem with grounding or some such.
