I installed 3 of these lights in my 11ft x 12ft office with a sloping ceiling. Took me about 40 minutes to install 3 lights. 5.25 inch holes in the ceiling by carefully measuring and checking for studs. =adjustable+hole+saw&qid=1582238983&sr=8-5 I connected them to my existing fan junction box which connects to a light switch. I then daisy chained each light together which was very easy with push in wire connectors. The light is almost too bright for my office, I use a GE dimmer to turn it on at about 80% brightness. I have no complaints yet.
