If you found this article, congratulations! girlfriend have established that the monster clicking sounds you’ve been hearing every 2nd day in your living room space most likely coming indigenous a irradiate fixture or bulb!
It’s tough to pinpoint an rarely often rare noise around the house, however now that you’ve lastly pinned that down, you have the right to solve the problem.
You are watching: Light fixture makes popping noise when turned off
LED bulbs make a clicking sound due to a variety of reasons that might be housed in the light fixture, in the dimmer system, or in the an extremely LED pear itself.
Why does LED do Popping Noise when Turned On?
A lot of human being with recessed can lighting experience a click sound once they are switched off and additionally briefly when they space turned on.
Surprisingly this has nothing to perform with the bulb or wiring but is because of the recessed fixture itself.
More specifically, when the can lighting fixture is not made through a good thermally insulating material, climate the body of the fixture heats up and also cools down unevenly, and the metal’s expanding and also contracting v the plastic make noises.
It is generally the trim that might be the culprit together it’s make from aesthetic material and not necessarily tested for heat dissipation.
The kind of sound it makes is irregularly spaced according to tinkling, much like the stove walls make once they room heating up.
The canned lights could also possibly be expanding and contracting against the drywall, the metal studs, or the foot that organize the fixture in place, so any number of mechanical things could be at play.
So save an ear the end for the kind of noise and when it occurs.
If girlfriend hear the clicking sound as soon as you revolve on a light fixture, it might be poor wattage that the dimmer switch at play.
You will absolutely need to take into consideration the wattage of your dimmer, and how numerous LEDs space on the circuit.
For example, if your dimmer wattage is 150 W, and also you have fifteen 9 W bulbs, you will think you’re in the clear.
However, when LEDs revolve on, there is ‘in-rush’ current, i m sorry is a huge surge of present that goes through the circuit to strength on the LEDs initially.
So not only do you need to take into consideration whether the LED bulb and dimmer are compatible v each various other correctly. Also, even if it is you have detailed enough headspace for the start-up present surge.
Also, one old dimmer device hooked as much as a new LED pear may permit some ‘leaking’ of current to take it place, as part dimmers carry out not switch off fully when turned off.
That is covered in much more detail in the ar below.

Let’s mean you deserve to hear click after you have actually turned off her dimmer switch, and a few minutes later, friend hear the noise. Why is that?
LED bulbs have circuits in ~ the basic 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, come 12 V that the LED needs.
Sometimes this circuitry deserve 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 completely turned off even when the dimmer is dialed under to zero.
So physically, the dimmer is quiet on, providing ever small voltage but not enough, and also this outcomes in a click noise.
Essentially, the dimmer is charging up a small capacity in the switching strength supply. When it builds up enough, that is discharged through a ‘click,’ audible to human beings every few hours or minutes.
Conversely, you may hear sound when you turn on one LED.
This is an in-rush sound the is actually an extremely hard come hear and also is more like a hum or a high-pitched whistle, and can only be audibly heard if the driver inside the LED is cheaply made.
There is yet one more reason that the bulb could be to blame. If the basic of the LED bulb is make of ceramic or aluminum, the can cause random popping noises time and again.
Most of the latest LED bulbs can get an extremely hot, and that noise is typically the base heater up.
In enhancement to the ceramic or aluminum, the bulb consists of materials such as metal, glass, and plastic.
Due to differing coefficients of heat expansion, the parts warmth up at different rates. They might touch and scrape past each various other as they expand, do irregular mechanically sounding click noises.
How To eliminate Clicking Noise?
There is a method to check a dimmer and LED combination that does no physically turn off.
If friend unplug her lamp or fixture completely from the wall, friend will see that the clicking will certainly stop. This confirms that is a residual voltage in the cheap LED driver.
The noticeable solutions, in this case, would be either to change the bulb or disconnect the circuit totally every time you desire to switch turn off the light, to stop the click noise.
Considering you’ve identified that that is your fixture, and also specifically the recessed deserve to lighting make noises, the problem is quickly resolved by replacing the trim or can.
Make certain that your fixture fittings and also wires are tightly secured, without lot room for loosening up.
To settle the high-pitched click or hum, the only solution is to exchange the bulb, and hopefully, friend can gain one that is great quality.
Don’t forget one of the most straightforward services to any type of electrical problem. Go you try and restart it? Or, in this case, did you try and unscrew climate re-screw the bulb?
That appears to tighten the connections and do away through noises for a the majority of people!
There are a couple of possible factors why her LED can be do a popping sound.

Did you come throughout any click sound from your LED pear or fixture?
At what minute do girlfriend hear it, and also can girlfriend make out if it’s a mechanical or an electric sound?
