I have installed several recessed lights in my basement finishing project all were wired up and running for weeks before I finished the drywall. Now I have one that is dead, I took the center piece out that you screw the bulb into to see if there were any bad connection but there are really none to check. These are IC Cans bought at the box store, hide sight I would now install all remodel cans in case I was to have a failure.
My question is can I take this apart ( by removing the 4 hex screws) and replace this can with a remodel unit if I have to?
