Humming Vibration Noise from Fixture
I have a bathroom light fixture that holds 8x40w g12 incandescent. Recently a noticed a very faint, intermittent humming/vibration noise. I can make it start and stop by tapping on the fixture.
There is no flickering or dimming of the light. I removed all the bulbs and I could not get it to make the same noise without any bulbs in it (rule out house wiring??).
I isolated it to one of the bulbs by reinstalling each seperately. I tired a new bulb in that socket and it still occured and I could toggle the sound again from tapping on the metal surrounding of the socket.
Do you think its safe to say its just a normal vibration sound from a quirky socket?
