Weird humming sound when I flip the light switch on
In my kitchen, when I flip on the light switch for the overhead lights (compact fluorescent, came with the light fixture kit, had 'em up for over a year now), I hear a high-pitched hum. It stops when I flip the switch off.
Weird. Could I have, maybe, never noticed this before?? I don't think so, really, but who knows!?
What could it be? Is it something I should have an electrician come out and check out?
