I bought a 4 pack of these lights, having 2 of the old style "eyeball" can lights and two bare bulb ceramic light to replace. When mounting to the j box, I had absolutely no issue at all. The can lights had a bit of a problem although I was able to get the job done. The wire that hold them into the cans were of a much large gauge wire and different shaped bends on the ends. I also found that attaching the wire to the fixture to be somewhat 'flimsy' but again made it work. All in all a good light for the money.
