I have existing recessed lighting that currently has incandescent bulbs in it. I want to replace the incandescent bulbs and existing trim with a new LED fixture. The problem that I am having is that my can seems to be about 4 7/8th inches in diameter. I have tried both a fixture for 4 inch cans and a fixture for 5 & 6 inch cans and neither option fit. Is my can a non-standard size or do I need to look for something else when purchasing new fixtures?
Here is what my existing can looks like. To me, this is a 4 7/8ths inch diameter can. But is that considered a 5 inch can?
This was a LED light that should work with 5 or 6 inch recessed light cans, it didn't fit at all:
