Light Fixture Buzzing: What It Means When the Buzz Changes With the Dimmer
A light fixture buzz that changes as you move the dimmer is often a lamp-and-dimmer compatibility problem, especially with LED drivers, but it can also involve a vibrating fixture, an unsuitable load, or an electrical connection. First record whether the buzz is only at the low end, present across the range, or loudest at the wall control or fixture, then check the lamp and dimmer model markings and compatibility instructions without opening anything.
