The other day we had a power outage and apparently surge that was enough to blow out the PSU on my computer. A day or two later I've noticed the ceiling light in my office is now clicking, regularly (around once a second at an estimate.).
It only makes this sound when it's powered on, stops immediately on powering off, but doesn't always make it even when powered on.
I've included a video of it, and I'm wondering what is causing it, is it dangerous and am I likely to be able to replace the broken part or will I have to replace the entire lamp?
The clicking starts around 10 seconds in, stops momentarily and starts again:
