If you found this article, congratulations! friend have determined that the weird clicking sound you’ve to be hearing every second day in your living room space most most likely coming native a irradiate fixture or bulb!
It’s hard to decide an rarely often rare noise around the house, but now that you’ve finally pinned it down, you have the right to solve the problem.
You are watching: Popping sound from light fixture when turned off
LED bulbs do a click sound due to a number of reasons that might be housed in the irradiate fixture, in the dimmer system, or in the very LED pear itself.
Why does LED make Popping Noise as soon as Turned On?
A many of world with recessed have the right to lighting endure a clicking sound when they are switched off and additionally briefly once they room turned on.
Surprisingly this has actually nothing to perform with the pear or wiring however is due to the fact that of the recessed fixture itself.
More specifically, as soon as the have the right to lighting fixture is no made v a an excellent thermally insulating material, then the body of the fixture heats up and also cools under unevenly, and also the metal’s expanding and contracting through the plastic do noises.
It is normally the trim that can be the culprit together it’s do from aesthetic material and also not necessarily experiment for warmth dissipation.
The sort of sound it makes is irregularly spaced according to tinkling, much like the oven walls make as soon as they are heating up.
The canned lamp could additionally possibly be expanding and also contracting versus the drywall, the steel studs, or the legs that hold the fixture in place, for this reason any variety of mechanical things might be in ~ play.
So store an ear the end for the kind of noise and also when that occurs.
If you hear the click sound as quickly as you revolve on a light fixture, it can be insufficient wattage of the dimmer move at play.
You will absolutely need to consider the wattage of her dimmer, and how countless LEDs room on the circuit.
For example, if your dimmer wattage is 150 W, and also you have actually fifteen 9 W bulbs, you will certainly think you’re in the clear.
However, once LEDs rotate on, there is ‘in-rush’ current, i m sorry is a large surge of existing that goes v the circuit to strength on the LEDs initially.
So not just do you need to think about whether the LED bulb and also dimmer space compatible with each other correctly. Also, even if it is you have listed enough headspace for the start-up current surge.
Also, an old dimmer device hooked as much as a new LED pear may enable some ‘leaking’ of present to take place, as part dimmers carry out not move off totally when turned off.
That is spanned in an ext detail in the ar below.

Let’s suppose you have the right to hear clicking after you have turned off her dimmer switch, and a couple of minutes later, girlfriend hear the noise. Why is that?
LED bulbs have circuits in ~ the base of the bulb. In ~ this circuit is the voltage regulator, i beg your pardon drops the AC main current to DC current, because that example, to 12 V that the LED needs.
Sometimes this circuitry have the right to make a ticking noise due to the fact that some voltage is tho applied.
This is because, in cheap LED bulbs, the voltage might not be fully turned off also when the dimmer is dialed down to zero.
So physically, the dimmer is still on, giving ever small voltage however not enough, and also this results in a click noise.
Essentially, the dimmer is charging increase a little capacity in the switching strength supply. Once it build up enough, it is discharged through a ‘click,’ audible to humans every few hours or minutes.
Conversely, you might hear sound as soon as you revolve on an LED.
This is one in-rush sound that is actually an extremely hard to hear and is much more like a hum or a high-pitched whistle, and can just be audibly heard if the driver within the LED is cheap made.
There is yet an additional reason that the bulb can be come blame. If the base of the LED bulb is made of ceramic or aluminum, it can cause random popping noises time and again.
Most the the latest LED bulbs have the right to get really hot, and that noise is typically the base heating up.
In addition to the ceramic or aluminum, the bulb is composed of products such as metal, glass, and also plastic.
Due to differing coefficients of thermal expansion, the parts warm up at various rates. They might touch and also scrape past each other as lock expand, make irregular mechanically sounding click noises.
How To get rid of Clicking Noise?
There is a way to check a dimmer and also LED mix that does not physically turn off.
If friend unplug her lamp or fixture totally from the wall, you will see that the clicking will stop. This confirms the is a residual voltage in the cheap LED driver.
The noticeable solutions, in this case, would certainly be either to change the bulb or disconnect the circuit completely every time you desire to switch turn off the light, to prevent the click noise.
Considering you’ve identified that it is your fixture, and also specifically the recessed can lighting making noises, the problem is quickly resolved by instead of the trim or can.
Make sure that your fixture fittings and also wires space tightly secured, without much room for loosening up.
To settle the high-pitched click or hum, the just solution is to exchange the bulb, and hopefully, you can gain one the is an excellent quality.
Don’t forget among the most straightforward options to any type of electrical problem. Walk you shot and restart it? Or, in this case, go you try and unscrew climate re-screw the bulb?
That appears to tighten the connections and also do away through noises for a the majority of people!
There are a couple of possible reasons why your LED could be do a popping sound.

Did you come across any clicking sound from her LED bulb or fixture?
At what moment do girlfriend hear it, and can girlfriend make the end if it’s a mechanical or an electric sound?
