I installed 20 in a 900 sq ft remodeled. ft. I had to trim a few sliders and it's easy. Just slide them together and break the small V in all the sliders. My only problem was that one didn't work. I had to remove the can and work through the hole since the drywall was finished. It turned out that the black wire had not been stripped before inserting it into the 3-hole connector. So there was no line. I took it off and put it back on and it worked. This scared me because at first I thought the wire broke when doing the drywall in the wall. I hope Sunco did better by checking the continuity from the orange LED connector to the connector in the back box. I'm sure this isn't the first time this has happened. Finally, it would be a good idea to punch a 4 inch circle in a box with 2 "handles" on 2 sides. Dust and paint during construction after their installation.
