Caution

As with any electrical project, always use caution. Always follow the manufacturer's instructions for installation and safety. Observe applicable building and electrical codes. Contact a licensed electrician if you have any doubts or questions about the connections or if your home's wiring doesn't appear compatible with the changes you're making.

Instructions

Before replacing your ceiling light fixture, open the electrical circuit panel and locate the room’s circuit breaker. Switch the circuit off. Use a circuit tester to verify the power is off. Place the wall switches for the fixtures in the off position.

If the circuits in your panel aren't labeled, turn on the existing light and turn off the power to each circuit until the light goes out (you may want someone to help you with this). Leave the power off and label this circuit breaker for future reference.

Check the electrical box in the ceiling where the fixture is attached. If the electrical box is loose, tighten the screws that hold it in place, but don't overtighten. The box must be compatible with your new light fixture.

Be sure that the box is securely attached to the building structure so it can support the weight of the fixture. It must also be grounded, meaning that it's attached to a ground wire in the ceiling. If you have doubts about the suitability of the existing box, purchase and install a new electrical box.

Follow the manufacturer’s instructions for matching the new ceiling light wiring to your home's existing wires. Black wires typically connect to black wires and white connects to white. A grounding wire, which is often green, connects to a grounding screw on the grounding bar.

Use a wire stripper to remove the new light fixture's protective wire coating. Wrap the bare section of each wire to the bare section of its corresponding existing wire. Screw on the wire connectors. Connect the grounding wire.

Changing an Exterior Light Fixture

The process of changing an indoor light fixture is very similar to replacing an outdoor light fixture. Make sure all power to the exterior of your house is turned off before you start. Be sure to choose an outdoor light fixture. These types of light fixtures have sealed inner components and are made from weather-resistant materials. Do not use an indoor light fixture on the exterior of your house. Updating your exterior light fixtures is an easy way to boost your home’s curb appeal and can be done in a few hours.

Is it safe to change a light fixture if the switch is off?

Always turn off the switch to a light and cut the power at the breaker before changing a fixture. Use a non-contact voltage tester to ensure the power is off. Wear a headlamp or use a work light so you can see what you're doing while the lights are off.

Do I need to cut the breaker to change a light fixture?

Yes, you must turn off the breaker. Don't skip this step just to save time — this could lead to electrical shock.
