Step-by-Step Instructions
Turn off power at the breaker
5 minutes
Go to your electrical panel and turn OFF the breaker for the light circuit. It's not enough to just turn off the light switch. Use a voltage tester at the fixture to confirm power is off.
Warning
NEVER work on electrical with power on. Always verify power is off with a voltage tester.
Remove the old fixture
10 minutes
Remove any glass shades or covers. Unscrew the mounting screws or nuts holding the fixture. Carefully lower the fixture, revealing the wires. Do not pull on the wires.
Pro Tip
Have a helper hold the fixture while you disconnect wires, or hook it on a clothes hanger from the box.
Disconnect wires and note connections
5 minutes
Take a photo of the wire connections. Remove the wire nuts by twisting counterclockwise. Separate the wires: typically black (hot), white (neutral), and green or bare (ground).
Pro Tip
If wires are different colors than standard, take detailed photos for reference.
Prepare the new fixture
5-10 minutes
Unpack and inspect the new fixture. Check that all hardware is included. If the fixture has a mounting bracket different from the existing one, install the new bracket.

10 minutes
Connect the fixture wires to the house wires: black to black (hot), white to white (neutral), green or bare to green or bare (ground). Twist wire ends together clockwise and secure with wire nuts. Wrap nuts with electrical tape.
Pro Tip
If house wiring doesn't have a ground wire, connect the fixture ground to the metal box (if metal).
Warning
Proper wire connections are critical. Loose connections cause fires. Tug each connection to ensure it's secure.
Mount the fixture
10 minutes
Carefully tuck wires into the electrical box. Align the fixture with the mounting bracket and secure with the provided screws or nuts. Don't overtighten.
Install bulbs and shades
5 minutes
Install the appropriate light bulbs (check fixture ratings). Attach any glass shades or covers.
Test the fixture
2 minutes
Turn the breaker back on. Test the light switch. If the light doesn't work, turn off the breaker and check all connections.
Common Mistakes to Avoid
- Not turning off power at the breaker (switch off isn't enough)
- Not verifying power is off with a tester
- Mixing up hot and neutral wires
- Loose wire connections
- Over-stuffing wires in a small box
Safety Warnings
- ALWAYS turn off power at the breaker, not just the switch
- ALWAYS verify power is off with a voltage tester
- If in doubt, call an electrician
- Never work on electrical when tired or rushed
When to Call a Professional
If there's no ground wire and you're uncomfortable, if existing wiring looks damaged or burnt, if you need to move the fixture location, or if you're not comfortable working with electricity.
