Safety note: hardwired fixtures and wall switches connect to household wiring. Turn off the breaker and confirm the power is off before you start, match the fixture to the box, and use a licensed electrician if you are not experienced with home wiring. Check the load rating, the box size, and your local code, and look for a UL or ETL mark. Listings differ; we describe what each maker lists.
