How to Add a Recessed Light Above a Mantle

Check the electrical circuit by adding up the watts of all items already on the circuit. The Family Handyman website recommends no more than 1,440 watts total for 15-amp circuits, or 1,920 watts for 20-amp circuits. Subtract the total already used from the total recommended watts to determine how much you have left for the recessed lighting fixtures.

Calculate how many recessed lighting fixtures you want to place above the fireplace mantel. Spacing of 3 to 4 feet gives you a concentrated area of light, while spacing of 6 feet or more casts a general glow toward the area. Consider the size of the mantle and how much light you want shining in the area when you decide if you want one fixture or more.

Identify the positioning of the light fixtures. Measure at least 1 foot from the wall so the fixtures are slightly in front of the mantle. Choose light fixtures that are adjustable so you are able to aim the lights toward the mantle.

Cut holes for the recessed lights. The fixtures should come with a template to guide the cutting process.

Shut off the power source for the circuit. Test the wires with a circuit tester to ensure the power is off. Lock the breaker panel, and let everyone in the house know you are working on the electrical system so they don't turn it back on.

Direct the wiring connected to the circuit to the opening for the recessed lighting fixture. This can be done through the attic or by fishing the wire through the wall and out the hole. If you aren't familiar with this process, hire an electrician to take over. Incorrect wiring may cause a house fire or electrocution.

Wire the recessed lighting fixture to the electrical source. Place wire connectors over the connections.

Guide the wires up into the hole. Slide the recessed lighting fixture into place. Refer to the manufacturer's directions for the specific lights you purchased, to ensure they are mounted correctly.
