recessed lighting, popping

Most likely it's from expansion and contraction from heat from the lights.
What else could it be?

That could be it. A few of the bulbs are not exactly centered in the recesses. They may be too close to the edges, causing the noise. I think we will have them looked at again, and hopefully fix whatever this is. Thanks so much

Sounds like something in these recessed lights is not securely fastened down, so that when they heat up, something pops loose. It odes happen after they have been on for a while, and have heated up, right?

You should check these out, and see that all the fixture screws & connectors are completely fastened. Probably not a life-threatening problem, but if left unfixed it is likely to shorten the life of these fixtures or bulbs.

Your right..they had been on for a bit. I will have all of that checked, just to be on the safe side. Thanks so much for your time.

I think all you need to do is to fasten all the connectors securely and make sure the recessed lighting fits snugly in the hole. Hopefully you have already fixed this problem.

We did. The electrician came out, and adjusted all the lights. Have not heard the noise again. Thanks so much for you time.

How old is your house? It could be a factor.

Mine pop all also. Even when you turn them off for awhile.

My recessed light pop immediately when I turn them on. The house is 5 months old.

One of my recessed lights just started clicking. It started this morning, lights were off and have been all night. We haven’t changed anything and the house is about 8 years old. Afraid it may be something dangerous?? It continues when light is turned on as well. We’re keeping it off just in case but it’s still doing it.

My house is 6 months old and only the kitchen recessed led lights pop as soon as they are turned on. The lights in the family room do not pop. I'm guessit must be a ground wire problem?
