Google is bringing me nothing so I am turning to the great minds at GT. We recently replaced the CFL bulb in an overhead lamp with a Philips LED bulb. Today I noticed the the lamp is gently vibrating when it’s on. It’s not overly hot and the light isn’t flickering or anything like that, the fixture is just vibrating a bit. I am quite sure it never did this before. At first we thought it might be interference from another appliance (it’s in the kitchen) but it seems to happen regardless of whether anything is on.

Any ideas of what that might be or if it is dangerous? I’d like to keep using LED bulbs and it isn’t annoying or anything, but I don’t want to burn my house down or destroy my lamp either. ;)
