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).
How do I stop my LED lights from buzzing?
But, if your lights hum when dimmed or installed into sockets connected to a dimmer, it’s simple to fix. LEDs do not dim the same way as incandescents. Simply cutting off a portion of the waveform will strain the driver within your LEDs and decrease the lifespan of the lamp.
Are buzzing LED lights dangerous?
Unfortunately, LED bulbs can sometimes make buzzing, beeping, humming or whistling sounds. They not only annoying and irritating but can also get on your nerves, especially when you’re trying to concentrate on something important.
Why is my recessed light buzzing?
A buzzing sound coming from an incandescent light fixture is most often caused by a defective light socket or a loose bulb. The buzzing sound is actually a manifestation of electrical arcing between the center contact on the base of the bulb and the button contact at the bottom of the light socket.
Why does my LED dimmer buzz?
Buzzing Dimmer Switches
Overloading your dimmer with excess wattage can also result in buzzing and humming. Change the bulbs: Buzzing coming from the fixture itself is usually related to bulb filaments. Longer filaments are more susceptible to electromagnetic changes, which can result in constant buzzing.
Do LED lights attract bugs?
Bulbs that emit more short wavelengths of light (cool white/bluish color) will attract more bugs. … LED lights produce little to no UV light and a minuscule amount heat, which makes them less attractive to bugs—so long as they emit longer wavelengths of light.
How long do LED lights last?
Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years.
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.
What is an LED compatible dimmer?
Dimmer Switches work by reducing the power delivered to your light bulb. They do this by trimming a section of a waveform, either on the leading edge or trailing edge of the wave. … Manufacturers have designed their LED light bulbs to be compatible with the majority of common ‘trailing edge’ household dimmers.
Do all dimmers buzz?
6 Answers. All dimmers buzz a little bit. They “chop up” the AC waveform, which creates mechanical vibration (buzzing) and electrical noise (EMI). Usually they are the most quiet when the lights are fully bright, and get louder as you dim the bulbs.
How do I stop my dimmer from buzzing?
Upgrading Your Dimmer Switch
If you’re wondering why your dimmer switch is still buzzing, it may be that it is rated too low for the task, and is being overtaxed by the combined bulb wattage. Try taking a few bulbs out of the switch circuit and see if it reduces the buzzing.
Can LED lights be dimmed?
The number one rule for successfully dimming LED lighting might sound obvious but it is a common misconception that any LED lights can be dimmed with an LED dimmer. … Choose ‘dimmable’ lamps but be aware that this in itself is not a guarantee of a good dimming performance. It is, however, a good starting point.
