Sometimes when a triac-based dimmer controls a light, it can produce an audible hum from the light bulb or the dimmer itself. Is this normal and, if so, what can be done to minimize it?. They notice that something is not quite right because the buzzing was not occurring before the switch was installed. How can I fix this problem?įrom time to time, we hear from folks who have noticed a buzzing sound coming from either their light bulbs or a newly installed light dimmer. It makes a loud buzzing sound when the lights are dimmed. I have eight 50-watt lamps connected to a single dimmer switch. Note: ELV dimmers require a neutral wire in the box.Why Do My Lights Buzz When Using a Dimmer? In my experience, ELV dimmers help or eliminate the buzz almost every time.
CL dimmers will eliminate the buzzing on most brands of LEDs, but not all.Įlectronic Low Voltage (aka reverse phase or trailing edge) dimmers are designed for electronic (capacitive) loads like LEDs. They have a low-end trim adjustment that allows you to get the best dimming range possible. My experience with them has been excellent. What you’re looking for is either a CL dimmer or an ELV dimmer.ĬL dimmers are made by Lutron and designed to be compatible with LEDs. Of all the dimmers on the list, there are two types to look for that will likely work best at eliminating the buzzing.
Most manufacturers now provide a list of recommended dimmers that they have tested to be compatible with their products. LEDs are electronic devices, and using a dimmer that was designed specifically for the resistive load of an incandescent lamp will seldom work well. The cause is almost always a compatibility issue between the dimmer and the LED’s driver (power supply). While most LED lights are dimmable, a common complaint is hearing a buzzing sound coming from the lights when they are dimmed. One of the great features of recessed LED lighting is the ability to dim the lights.
