I finally got permission to install 2 of these lights.  They would not work on a remodel canister, so I tried to install in another room. The holes for the screws were blocked by the frame of the fixture, so could not get them into the canister.  Also, one of the fixtures was missing parts.  The website says I can no longer return them.  So, I have two beautiful fixtures that are not usable and I am out a lot of money.
