Changing the bulb in an enclosure
That looks like an integrated LED can retrofit fixture (a close match for some of mine - I see the supply converter screwed into the original can socket) and you replace the whole thing - there is no removable bulb.
If you enjoy tinkering the LEDs are probably fine, and the driver circuit is probably dying, but that's strictly &quot;reuse LEDs for your low voltage projects&quot; not &quot;do a home replacement and return it to service at line voltage with unlisted parts and repairs&quot; - for fixing the light in this location that's attached to mains voltage, just buy a new LED retrofit with all the proper listings so that you don't void your insurance...
