Project Snapshot

Replacing a faulty light fixture involves shutting off power, carefully disconnecting the old unit, matching and connecting the correct wires, and mounting your new fixture securely. The whole project generally takes less than an hour for a single standard light and can quickly transform a space. A little attention to electrical safety keeps the job straightforward and stress-free. With a wide array of modern lighting styles available, this is a DIY win for any room.

Tools and Materials

You'll need a flathead and Phillips screwdriver, voltage tester, wire stripper, pliers, step ladder, and electrical tape. Supplies include the new light fixture, compatible light bulbs, and new wire nuts (usually included with the fixture). Keep a flashlight handy, especially if you're working after turning off a breaker. Use a drop cloth to catch any dust or loose screws. Safety glasses and gloves are a smart choice to protect from debris and sharp edges.

Step-by-Step Instructions

1. Turn off power to the existing fixture at the circuit breaker and confirm with a voltage tester. 2. Remove the old fixture cover and bulbs, then unscrew the mounting hardware. 3. Gently lower the fixture and disconnect wires by removing wire nuts. 4. Note or photograph how wires are connected (typically black to black, white to white, and green or copper to ground). 5. Assemble your new fixture as directed by its instructions. 6. Connect the new fixture wires to the matching house wires using fresh wire nuts; wrap with electrical tape for extra security. 7. Secure the new fixture to the ceiling or wall bracket with the provided screws. 8. Install bulbs and fixture cover, then turn the power back on to test your installation. 9. Dispose of or recycle the old fixture responsibly.
