How To Add Overhead Lighting to a Bedroom

Adding overhead lighting to a bedroom can dramatically improve its functionality and ambiance. This DIY project requires some electrical know-how and careful planning, but it can be a manageable DIY task with the right approach. In the video above, This Old House expert electrician Scott Caron walks us through the process of installing overhead lighting in a primary bedroom. You can learn more about how to complete this home lighting upgrade yourself in our step-by-step guide below.

Planning Your Overhead Lighting Installation

Before installing your new lighting, plan its location and verify available power sources by following these steps:

Step 1: Choose the Right Location

Instead of placing the light directly over the bed, center it in the room’s largest open area. This approach provides flexibility if you decide to rearrange your furniture in the future and helps create well-balanced illumination throughout the room.

Here’s how to determine the best location for your overhead lighting:

1. Measure between two opposing walls and mark the center with painter’s tape.
2. Measure between the other two opposing walls along the line designated by the painter’s tape.
3. Move the painter’s tape to the center of that line (where your two measurements intersect). This is the center of the room.

Step 2: Assess Power Sources

You’ll need a reliable power source for your new lighting fixture. Consider these power source options:

• Existing outlets in the room
• Nearby light switches or fixtures
• Power sources in the attic above

Once you’ve located a power source, make sure it can handle the new fixture’s additional electrical load. If you’re unsure, consult a licensed electrician to assess your home’s electrical capacity.

Tools and Materials To Add Overhead Lighting

You’ll need to gather the following tools and materials for this project:

• 14/2 nonmetallic cable
• 4-inch hole saw bit
• Bellhanger bit
• Carpenter’s pencil
• Dimmer switch
• Drill/driver
• Electrical tape
• Fish tape
• Ladder or scaffolding
• Light fixture
• Old work electrical boxes (for switch and ceiling)
• Oscillating multitool
• Spade bit
• Tape measure
• Voltage tester
• Wire nuts
• Wire strippers

Installing Overhead Lighting: Safety Precautions

Safety is paramount when working with electrical appliances. Take these precautions for a safe installation:

• If you’re unsure about any step in the process, consult a licensed electrician.
• Turn off power at the circuit breaker before beginning any electrical work.
• Use a sturdy ladder or scaffolding when working on the ceiling.
• Use a voltage tester to confirm that the power is off before handling any wires.
• Wear safety glasses and gloves when cutting into walls or ceilings.

How to Install Overhead Light

Follow the steps below to complete your overhead lighting installation.

Step 1: Locate the Switch

Choose a location for your switch that’s easily accessible and complies with local building codes. You can typically install switches in the following locations:

• 48 inches from the floor to the center of the box
• Away from any existing outlets or switches
• On the wall nearest the room’s entrance

Step 2: Cut the Switch Box Hole

1. Use a stud finder to make sure you’re not cutting into a wall stud.
2. Trace the outline of the old work switch box on the wall.
3. Score the outline with a utility knife to minimize paint chipping.
4. Cut the hole using an oscillating multitool.
5. Insert the old work switch box and secure it according to the manufacturer’s instructions.

Step 3: Drill and Fish Wires

If possible, run your wires through the attic space above the room. This method is less invasive and easier than fishing wires through finished walls. Be careful not to damage any existing wiring or insulation while working in the attic.

Follow these steps to run your wires:

1. Drill a hole through the top plate of the wall where the switch is located.
2. Use a 4-inch hole saw to cut an opening for the ceiling box where you’ll install the light.
3. Fish 14/2 nonmetallic cable from the switch location to the ceiling box location.
4. Run another length of 14/2 cable from the power source to the switch location.
5. Secure the cables with appropriate staples to avoid any future issues.

Tip: As you run your wires, consider labeling them for future reference. This can be particularly helpful if you need to troubleshoot or modify the wiring later. Use adhesive labels and a permanent marker to specify each wire’s purpose.

Step 4: Install the Ceiling Box

Select a ceiling box that can support the weight of your light fixture. If you plan to upgrade to a ceiling fan later, opt for a fan-rated box. Make sure the box provides sufficient space for all wiring connections and install it as follows:

1. Insert the box into the hole you cut earlier.
2. Secure the box according to the manufacturer’s instructions, ensuring it’s flush with the ceiling surface.
3. Double-check that the box is firmly in place and can support the fixture’s weight.

Step 5: Complete Electrical Connections at the Switch

1. Strip about 6 inches of sheathing from the cables in the switch box.
2. Connect the wires according to the dimmer switch instructions, typically as follows:
   • Black (hot) wire from the power source to the black wire on the switch
   • Black wire from the switch to the black wire going to the light fixture
   • Ground wires connected together to the switch’s ground screw
   • White (neutral) wires connected together

 Step 6: Connect the Ceiling Box

1. Strip about 6 inches of sheathing from the cable in the ceiling box.
2. Connect the wires from the cable to the corresponding wires on your light fixture, typically as follows:
   • Black to black
   • White to white
   • Ground wire to the fixture’s ground wire or screw
3. Secure all connections with wire nuts and wrap them with electrical tape for added security.
4. Make sure there are no exposed wires that could cause a short circuit.

Step 7: Mount the Light Fixture

1. Follow the manufacturer’s instructions for mounting the fixture to the ceiling box.
2. Make sure to neatly tuck all wires into the box to avoid pinching or damage.
3. Use the screws provided to secure the fixture to the ceiling box.

Step 8: Add Finishing Touches

1. Secure the fixture’s canopy to the ceiling, covering the box.
2. Install light bulbs that are compatible with the fixture.
3. Attach any shades or globes that came with the fixture, ensuring they are securely fastened.

Step 9: Test the Light Fixture

1. Restore power at the circuit breaker.
2. Test the switch to verify the light turns on and off properly.
3. If you installed a dimmer, check that it functions correctly across the dimming range.
4. Look for any signs of flickering or buzzing, which could indicate a wiring issue.

Step 10: Complete Final Touch-Ups

1. Patch any holes in the wall or ceiling with appropriate filler.
2. Touch up the paint to match the surrounding area, blending any repaired spots seamlessly.
3. Clean your workspace, ensuring you don’t leave any leftover materials or tools behind.
4. Dispose of any cut wires or packaging materials responsibly.
