If you're looking for a simple way to upgrade a living space, try replacing your light fixture with a new pendant or chandelier light. Installing a light fixture is an intermediate DIY project you can accomplish in as little as two hours. It requires basic electrical skills, a screwdriver, and a new fixture. In this guide, we'll teach you how to install a new light with or without existing wiring.

Things You Should Know

Switch the circuit breaker to the "OFF" position to replace a light fixture. Then, unscrew the canopy and wires in a counterclockwise position.
To install a fixture without existing wiring, cut a hole in the wall and ceiling for a junction box and the fixture. Thread an electrical Romex cable through each hole.
Connect the wiring to the new fixture by twisting the corresponding wires clockwise. Place the wire nuts over the wires and mount the fixture.

Switch the appropriate room's circuit breaker panel to the "OFF" position. Every home and apartment has a circuit breaker, which controls all of the electrical power in the home. Look for a matte grey metal box in the basement, garage, utility closet, or hallway. Each circuit controls the power to a specific room. Flip the corresponding switch to the "OFF" position before handling any wires. ^{[1]

- For example, if you're changing a light fixture in the living room, look for the corresponding "LIVING ROOM" circuit breaker.
- If you're working with an older circuit breaker, you may have fuse blocks instead of switches. Pull the fuse block out; either side will have an "ON" and "OFF" label. Insert the fuse block with the "OFF" side facing up.
- Always shut the power off before any electrical job to avoid electrical shocks or hot wires.

Don't take chances when working with electricity. Jeff Huynh, the general manager of Handyman Rescue Team, says: "The first thing to do when installing a light is turn off the power. Turn the switch off and the power off at the breaker. If you're unsure which breaker turns the power to that room off, shut the whole panel off."
