I paid an electrician one hundred fifty dollars to replace a hallway light fixture. He was in and out in twenty minutes. I watched the whole thing and realized I had paid someone four hundred fifty dollars an hour for something I could have done myself.

Replacing a light fixture is one of the safest electrical projects you can do. You are connecting three wires — black to black, white to white, ground to ground.

Safety First: Turn Off the Breaker

Find your breaker panel. Identify the breaker for the room. Flip it to OFF. Go back to the light, confirm it does not turn on. Use a non-contact voltage tester (ten dollars at any hardware store) to confirm wires are dead. Breaker labels are sometimes wrong.

The Three Wires

Inside the ceiling box you will find: black (hot), white (neutral), and bare copper or green (ground). Your new fixture has the same three. Connect them using wire nuts — twist exposed copper ends together clockwise, then screw the wire nut on clockwise until tight. Tug each wire gently to confirm it is secure.

Heavy Fixtures Need a Strong Box

Most ceiling boxes are rated for fifty pounds. If your new fixture is a ceiling fan or heavy chandelier, check the box rating. A fan-rated box is required for anything over thirty-five pounds.

When to Call an Electrician

If you see cloth-wrapped wires (pre-1960s wiring), stop and call a pro. Also call if you see scorching or water damage.

For a standard light fixture swap in a house built after 1980, you can do this. Turn off the breaker, test with a voltage tester, connect three wires, and you are done.
