I have a buzzing sound coming from in ceiling light fixtures.
The fixtures are Liton LH1499IC (https://liton.com/ic-double-wall-housing-51083.html)
- These fixtures are connected to a dimmer switch
- Buzzing from the fixtures gets worse over time (as the light stays on)
- Buzzing gets worse with full brightness
- Buzzing gets worse if I completely remove the bulb but have the dimmer ON
- Buzzing 100% comes from the fixture itself and not the bulb, I can hear it from inside the fixture and as mentioned, if the bulb is completly removed the fixture buzzes worse
- Bulbs are 12V 50W which is what the fixture says to use. I tried changing to 12V 30W and 5W just to see what happens and the buzzing actually got much worse with the 5W as well
My first thought was to buy new fixtures and replace the old ones, but looking at the picture of that fixture it looks like its going to be alot of work (i've never replaced light fixtures before).
Next thought was could there be a relationship to the dimmer switch?
To be clear, the dimmer has no sound or buzzing whatsoever. But is it possible the wrong dimmer switch is connected and that is creating a buzz downstream at the fixture?
Dimmer is Lutron SLV-600P (https://www.lutron.com/en-US/Products/Pages/StandAloneControls/Dimmers-Switches/SkylarkDimmer/ModelNumbers.aspx)
- 120 V / 600 VA (450 W)
- I have 4 light fixtures connected to it, those are 12V, 50W each. MR-16
Bulbs are Osram 12V 50W MR-16 base bulbs
Is there any rule of thumb I can use in determining if the correct dimmer switch is paired to the correct fixture, or does it not matter? I'm essentially both hoping and wondering there is an easier solution to this problem then changing the fixtures
As you can tell, I'm a total noob.
Any help is much appreciated!
