Changing a light fixture is a simple DIY task that beginners can do. Here is a step-by-step guide:

1. Turn off the power: Before starting, turn off the power supply to the light fixture at the circuit breaker.

2. Remove the old fixture: Unscrew the screws or nuts that hold the fixture in place. Disconnect the wires and remove the old fixture.

3. Install the new fixture: Connect the wires from the new fixture to the corresponding wires in the electrical box. Use wire nuts to secure the connections.

4. Attach the new fixture: Secure the new fixture to the electrical box using screws or nuts.

5. Turn on the power: Turn on the power supply at the circuit breaker and test the new light fixture.

Remember to always follow safety precautions and consult an electrician if you are unsure.

Upgrading a space in your home can be achieved quickly and easily by changing a light fixture. This simple project can rejuvenate a room or add a touch of personal style to a rented space. Replacing a flush or semi-flush fixture is a great starting point for learning basic DIY skills, but it’s important to be cautious when working with electrical circuits to ensure safety. The following steps outline the standard process, but always follow the manufacturer’s directions when installing your own fixture. If you’re uncomfortable at any point during the project, stop and call an electrician for assistance.

Materials:

  • Painter’s tape

  • Ladder

  • Flat and Philips screwdrivers

  • Noncontact voltage tester

  • Replacement light fixture

  • Wire stripper pliers

  • Wire nuts

Steps to Change a Light Fixture

1. Turn Off the Electricity

The first and most important rule is to ensure the wires you’re working on have no electrical current. For this project, you’ll need to test twice for the absence of electrical current, once now and again later, before touching any wires.

  • Locate the electrical service panel or breaker box.
  • If the breaker switches are labeled, turn off the one designated for the light fixture you’re going to replace. Toggle the switch from the “on” side to the “off” side.
  • If the switches aren’t labeled, try several of them one at a time until you find the right one.
  • Flip the light switch for your fixture to make sure the fixture doesn’t light up. If it lights up, go back to the service panel and try another breaker switch. Continue this process until the light fixture no longer illuminates. Don’t forget to relabel the breaker switch for next time.

Tip:

Use painter’s tape to cover the breaker switch as a reminder that it’s turned off for an important reason.

2. Disassemble the Fixture

Most flush-mount and similar light fixtures consist of several pieces that need to be removed to replace the fixture.

  1. Set up a ladder that’s tall enough for you to work comfortably on the fixture. Avoid setting the ladder directly under the lamp. Setting it slightly off to one side will make your work easier.
  2. Identify how the cover glass is attached to the rest of the fixture. Typically, there will be a decorative nut in the cover’s center or two to three setscrews around the edge of the base close to the ceiling.
  3. Hold the glass with one hand while loosening the retaining nut by hand or the setscrews with a screwdriver.
  4. Remove the screws or retaining nut, pull the cover away from the fixture base, and set it aside.
  5. Remove the light bulbs.

Tip:

If you plan to reinstall the fixture before moving out of your home, store the mounting hardware in a plastic bag with the fixture.

Step 3: Remove the Light Fixture

There are three different ways that your light fixture may be attached to the ceiling. Before proceeding, it is important to test the electrical circuit again to ensure that there is no power present before touching the wires.

  1. Test your noncontact voltage tester by holding it near an electrical outlet that you know is turned on and live. If there is a current, the tester should light up to indicate this.
  2. At the light fixture, locate a pair of screw heads or a cylindrical nipple with a brass-coloured nut around it, or both. If there are a pair of screws, use a screwdriver to turn them counterclockwise until the fixture’s mounting base lowers from the ceiling. If there are no screws present, twist the nut around the nipple counterclockwise until it is free and lower the base unit a few inches while supporting the fixture so it doesn’t hang from the wires.
  3. Use the voltage tester to test each wire and make sure there is no power. If voltage is detected, reinstall the mounting hardware and call an electrician for help. Do not proceed with the project.
  4. Lower the fixture until you reach the wire nuts connecting the wires. You may need to coax the wires out of the mounting box.
  5. Make note of which colour wires are attached to each other. Label them if necessary.
  6. Remove the wire nuts by twisting them counterclockwise from the wires.
  7. If a green or bare copper ground wire is attached to the electrical box with a screw, loosen the screw and remove the wire.
  8. Most light fixtures have a mounting bracket held by two screws to the electrical box. Remove these screws and the bracket.

Step 4: Install the Mounting Bracket

Your new fixture should come with its own mounting hardware and bracket to make installation easier.

  1. Use short machine screws to secure the bracket to the electrical box.
  2. Twist the mounting screws or nipple cylinder clockwise into the corresponding holes in the bracket. Use just a few turns to hold them in place; you’ll tighten them later.

Step 5: Connect the Wiring

It may be beneficial to have someone else hold the fixture while you connect the wiring, but it is possible to do it alone without much difficulty.

To replace a light fixture, you will need wire nuts, screwdrivers, and possibly a wire stripper. First, strip 1/2 inch of insulation from each wire if they’re not bare. Then, pair up and twist together the black and white wires with wire nuts, making sure they’re tight. Connect the ground wire according to the manufacturer’s instructions, either to the support bracket, circuit cable’s ground wire, or other elements. If there’s no ground wire, wrap the fixture’s ground wire around the green screw and secure it in the designated hole in the bracket. Next, mount the fixture by lining up the mounting holes with the screws or nipple in the bracket, tightening them until the fixture is snug, and screwing in the light bulbs and cover. Finally, restore power and test the fixture. For a visual guide, check out HouseImprovement’s video tutorial.
