Replacing a light fixture is one of the most satisfying electrical upgrades and a great way to quickly transform a room. Choose a fixture suitable for the amount of light you need. Never boost the illumination by installing bulbs of a greater wattage than the fixture is rated for. As with any electrical upgrade, shut off the power before beginning and use a circuit tester to confirm the power is off.

What You’ll Need: Circuit tester, small slot or Phillips screwdriver, coat hanger, diagonal cutting pliers, wire stripper, new light fixture, wire nuts, electrical tape

 

Step 1: Remove the Old Fixture

Confirm that the power is off by turning the wall switch off and on. The fixture should not light up. Remove the bulb(s) and detach the old fixture from the box. The type shown attaches with a nut and threaded post.


Step 2: Detach the Wires

Use a bent piece of coat hanger to hang the fixture from the box in order to support it. Unscrew the wire nuts and detach the wire connections.

With diagonal cutting pliers, nip off the bit of bare wire used for the connection. Strip off 3/4 in. of insulation. Then install the new strap that comes with the replacement fixture.


Step 5: Connect with Wire Nuts

To avoid straining the connections, temporarily hang the new fixture from the box with the bent coat hanger. Beginning with the uninsulated or green insulated copper grounds, hold the stripped ends side by side and twist on a wire nut, turning it clockwise. Connect the white wire to the white wire and the black to the black.


Step 6: Secure the Connections

Wire nuts twist the wires around each other while securing them. Give each wire nut a pull to confirm that the connection is tight. Wrap a couple of inches of electrical tape around the wire and nut to secure the connection.


Step 7: Install the Fixture

This fixture uses screws for mounting to the box. Some use a threaded post as shown in Step 1. Start the mounting screws in the strap, position the fixture, and tighten the mounting screws.


Step 8: Install the Bulbs and Globe
