Replace a light fixture

Swapping a fixture is easy to do and easy to do wrong. Switch off the breaker, test the wires, and support the fixture’s weight with a box rated for it. The video here looks at an older house where the wire insulation is only rated for a lower temperature than the fixture needs, which can cause overheating and a fire risk. Always check the fixture’s label for its wire rating.

If the wiring is old, cloth-covered, or brittle, you may need an electrician to repair or replace it. Fans are heavier and move, so a fan needs a fan-rated box; read our ceiling fan box rating guide first. For most fixtures, the same steps as replacing a light switch apply.
