How do I stop my LED dimmable lights from buzzing?

If you’re using a dimmer that is recommended by the manufacturer for your LED lights and all of the lights on the circuit still buzz, you only have two options. Option 1 – Remove the dimmer switch and replace it with a standard on/off switch. Option 2 – Replace the LED lights with a different model.

Why are my dimmable LED lights buzzing?

What is this? Almost every time the reason for LEDs humming when used with a dimmer switch is when the bulb’s power supply, aka driver, is incompatible with a dimmer system. It is actually the solid-state driver making the buzzing noise, and not the lighting emitting diode itself.

Why are my dimmable bulbs buzzing?

The dimmer will reduce the flow of electricity by removing parts of the AC voltage when dimming is engaged. Many inexpensive or lower quality dimmers will not properly reduce this flow, and a resulting buzzing sound can be heard.

Why is my LED light bulb buzzing?

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.

Do all dimmers buzz?

Here’s a fun fact: Almost all dimmers hum. When the room is absolutely silent, and the bulbs have been dimmed down to less than 50%, you put your ears close to the dimmer switch. Chances are, you will hear some buzzing or, at the very least, humming.

Do LED lights need special dimmers?

Yes, LED lights require a special dimmer. An old fashioned incandescent dimmer switch will not work properly with LED bulbs. You cannot just simply lower the voltage to the LED driver.

Is it normal for a dimmer to buzz?

Dimmer switches do make a slight buzzing sound due to the interruptions to the electromagnetic field that naturally exists around a live wire. A buzzing sound from the switch is usually not dangerous, unless accompanied by a hot switch or a crackling noise.

How do I stop my lights from buzzing?

To work around this, replace the bulbs with lower-wattage CFLs or LEDs. Upgrade your dimmer or ballast: Cheaply made dimmers and magnetic ballasts are likely to cause buzzing. Installing a higher-quality replacement may be necessary to stop your light bulbs from making this annoying sound.

Can a buzzing light switch cause a fire?

This causes the crackling sound, and it can lead to burned contacts and heating of the switch and the wiring connected to it—all problems that have the potential for causing a fire.
