How Dimmers Work
Solid-state light dimmers do not change the amount of electricity going into a light. They change the amount of time the full power line voltage goes to the light. They turn the power to the light off and on which makes the light look dimmer.
RFI: Radio Frequency Interference
The power that comes out of the outlet is a pure sine wave, with no harmonics. But the dimmer switching the power on and off makes high frequency harmonics, sometimes an audible hum.
How Can You Get Rid of Buzz?
A better quality dimmer might help. Every Lutron dimmer contains a filter to suppress RFI, radio frequency interference.
Get Rid of Transformer Buzz
Magnetic transformers are often the source of the hum. Magnetic transformers usually cost less than electronic transformers and are often for much higher wattage. But, if they are dimmed, they buzz. The lights can buzz, too. This happens with Monorail and Cable Light.
Why does my dimmer switch make a humming noise?
Some dimmer switches have different operating mechanisms, using a variable rheostat in which it is perfectly normal for the switch to make a very slight humming noise when the switch is moderating the electrical current to dim down the light intensity.
Why does my switch buzz?
A switch may buzz simply because the screw terminals connecting the circuit wires to the body of the switch are loose. The sound you hear is an audible signal that the electrical current is jumping a gap across metal connections that aren't in firm contact. The first step, then, is to check for loose wires.
What does it mean when a wall switch is buzzing?
Sizzling, popping, or crackling sounds when a wall switch is turned on and off may well mean the switch is defective or worn out.
How to check if a switch is loose?
The first step, then, is to check for loose wires. Shut off the power to the switch, then carefully remove the cover plate on the switch and examine the screw terminals along the sides of the switch to make sure they are securely fastened down over the circuit wires.
What type of dimmer to use for buzzing?
What you’re looking for is either a CL dimmer or an ELV dimmer. CL dimmers are made by Lutron and designed ...
What is an ELV dimmer?
Electronic Low Voltage (aka reverse phase or trailing edge) dimmers are designed for electronic (capaci tive) loads like LEDs. In my experience, ELV dimmers help or eliminate the buzz almost every time.
Why do LED lights make a buzzing noise?
The cause is almost always a compatibility issue between the dimmer and the LED’s driver (power supply).
Who makes CL dimmers?
CL dimmers are made by Lutron and designed to be compatible with LEDs. My experience with them has been excellent. They have a low-end trim adjustment that allows you to get the best dimming range possible. CL dimmers will eliminate the buzzing on most brands of LEDs, but not all.
Do ELV dimmers require a neutral wire?
Note: ELV dimmers require a neutral wire in the box.
How to return a buzzing LED lamp?
The best way to return a humming or buzzing LED lamp without any problems is through buying online. Due to the right of withdrawal, annoying luminaires and illuminants can be returned to all reputable online shops without any problems.
Why does my LED light make a buzzing noise?
Some LED ceiling lights with integrated LED’s emit a buzzing sound during operation. This is caused by the LED driver as described above. This is installed in the base of most ceiling luminaires. Even if the driver circuit itself barely hums audibly, the base of the luminaire serves as a resonance body in some constructions. This amplifies the buzzing and is audible throughout the room.
What happens if an LED lamp hums?
If the LED lamp hums or beeps too loudly, only an exchange will help. In my experience, the sounds of several lamps of the same type are sometimes different in intensity. However, it is hardly to be expected that when exchanging for the same LED type no more noises will be heard.
What frequency does a humming sound?
When humming or buzzing is heard, this usually occurs with a frequency of 120 Hertz. This corresponds to twice the mains frequency. This results in current peaks of 120 times per second. This can cause the components to vibrate or oscillate.
What is the noise of LED lights?
The noise can be different and is often described as follows by different people: Buzzing. Humming. Whistling. Whirring. Beeping. Such noises with the recently purchased LED lamp often causes astonishment and annoyance. Especially high-frequency buzzing is often perceived as a tinnitus, especially by younger people.

The brighter your light setting, the more quickly the current will switch back on after the interruption, supplying the light bulb with a greater amount of energy per second. For dimmer settings, the current will be turned off for a greater proportion of the AC cycle.
Why does a light bulb make a buzzing sound?
The result is that the light bulb appears dimmer, but it actually takes more electrical current to divert the current through the resistor. The resistor can thu s sometimes overheat and cause vibration in the electromagnetic field, emit ting that buzzing sound.
How to connect a dimmer switch to a circuit?
If the wire ends on the new dimmer switch have not already been stripped, use the wire strippers to strip off 0.5 inches or 12.7mm of the insulation on each of the wire leads. Then use a wire connector to connect the ground lead on the switch to the circuit ground wire in the switch housing. Next, connect each of the live wire leads on the switch unit to one of the live circuit wires in the housing. If the housing contains any neutral wires, they won't normally be connected to the switch.
Why does my switch buzz?
If it's a wired switch, then the wiring may be loose, faulty, wrongly wired or not grounded properly. The circuit may be overloading or arcing, or might at any moment fail to shut off.
