Recessed Can light making noise


Awhile ago i installed two 6'' halo LED recessed can lights in my bedroom above my bed. I noticed that one of the lights makes a noise every now and then. Its not consistant but it is noticable when sitting in the room for a extended period of time.

The best way to discribe this noise i would say it is a single "clink"
the light is not shorting out or arching or flickering.

I would say it is just the metal in the can heating up and causing this noise. But only one light is doing it.

Anybody every hear of a can light making this "clinking" noise? or what might be going on?

Thanks.

I pulled switch power off of the closest receptacle, witch also powers a few other things in this room. Tv and fish aquarium.

Could this be the issue? Should i have pulled power from a lighting circuit instead of the power circuit?

Does not sound like an electrical problem.
It could be the metal heating up, and a loose rivet or something in the can.

LEDs are tricky from the manufacturing standpoint, because of heat issues --

My guess -- as you and others have also -- is the heat is causing this noise at some point --there's expansion / contraction going on.

Heat "sinking" is very critical to LED life performance -- I wonder if there's a difference between the 2 fixtures, and the heat sink is "loose?"

Will be interesting to know what you find out.

Swap the bulb between the one clicks and one that does not.
