Simply so, are Buzzing dimmer switches dangerous?
The appliances and devices in your home are responsible for most of these noises. But, some electrical noises or humming can be very dangerous. Dimmer Light Fixture Humming: If a dimmer light fixture is humming, it is almost always caused by the light bulb.
Secondly, do all LED dimmer switches buzz?
While most LED lights are dimmable, a common complaint is hearing a buzzing sound coming from the lights when they are dimmed. The cause is almost always a compatibility issue between the dimmer and the LED's driver (power supply). CL dimmers will eliminate the buzzing on most brands of LEDs, but not all.
LEDs lack a filament or firing arc so there are no “moving parts” to cause humming. Unfortunately, LEDs still suffer from electromagnetic (EM) hum caused by incorrect dimming or EM interference by other devices. But, if your lights hum when dimmed or installed into sockets connected to a dimmer, it's simple to fix.
