I installed 3 of these lights in my 11 x 12 foot sloping office. Took me about 40 minutes to install 3 lights. Home Depot to cut 5.25" holes in ceiling, carefully measure and check for studs. =sr_1_5?keywords=adjustable+hole+saw&qid=1582238983&sr=8-5 I tied them to an existing fan junction box that connects to a light switch. wire connector. These lights are almost too bright for my office, I use a GE dimmer to turn them on at about 80% brightness. So far I have no complaints.
