Im doing a kitchen at the moment. There are a few 5" recessed lights right now. I am adding 10 more and replacing the existing. The fixture I use is a lightolier 1004 icr. Its a 5" old work can. My problem is that the rough opening for the lightolier is 5 1/8. I already cut the new ones in. When I took the old ones out they have a rough opening of 5 5/8. The lightoliers now are too small and push right through the hole without grabbing the drywall. My fault. I should have measured old ones first. Juno makes a can that is 5 1/2 but I need to match the trims since they are all next to one another. Any ideas?
