LED wafer lights “clicking” after being shut off

I recently installed some Halo 6” wafer style LED fixtures.

They have the junction box driver and operate at 36V DC 120V input.

After they are shut off there is a clicking sound. Not all fixtures do it, it stops after about a minute.

Expansion/ contraction???

I’ve installed hundreds of wafer lights ( Lithonia, Sunco, etc and never had this.
 
It does sound like expansion or contraction so that begs the question "Are the cans that are making the noise under insulation and thus retaining the heat more than the others?

No insulation. These are can less thin wafer type lights.

Sitting above drywall in a totally open space.
 
Do the lights have to be turned on for a while for this to happen? Or does it do this when they've been off for a long time, you turned it on for say 5 seconds, and then turned it off? If it doesn't have clicking in the second case then it's likely caused by thermal expansion and contraction.

I need to time the occurrence and see if there’s any consistency.

I am going to call Cooper Lighting (Halo) tech support tomorrow and see if it’s a common problem they are aware of.
 
Pull one clicking light out and run it on an extension cord. Probably facing down to be consistent.

It’s frustrating. Not all of them do it. 36 fixtures total throughout. Difficult to be in all the rooms to listen for specific ones in the timeframe that it takes place.

I’ll try your suggestion with a known culprit.
 
It's probably thermal, something shrinking and moving as it cools off. Are these the kind that have the spring steel wings that friction fit into a ring you mount to the box?

There is a metal mounting plate that gets installed at rough in. It has a 6 1/4” hole in it that the drywall hangers cut out. Just like they would zip out a conventional 6” housing.

The remote driver mounts to the plate with 2 nuts.

All is accessible through the hole once it’s been cut in the ceiling.

I strongly suspect I will be changing out the drivers and wafers. Customer does not appear to want to accept them as they are.

I’m gonna talk to Cooper Lighting tech support tomorrow but highly doubt there is a easy remedy.

What makes me mad is that I’ve used hundreds of the online “cheaper “ wafer LED’s and never had any issues.

I use a name brand product at 3x the cost and end up with this.
