Ceiling lights with at least two bulbs not just provide more light than a single-bulb fixture, but they often are decorative and decorated also. Whether the new lighting fixture is flush with the ceiling or a hanging fixture, you can install a ceiling light that has two lights to a single junction box to ensure all of the bulbs in the new fixture have been controlled by exactly the same switch. In many cases, you can even link the new fixture into a dimmer switch to control the quantity of light provided by the fixture.
Switch off the circuit breaker supplying power to the electrical circuit for the lighting. Remove the plate covering the light switch, and then hold the tip of a noncontact electrical ripped against the wiring on the side of the switch. If the tester light comes on, there is still power to the circuit. Turn off other the main breaker into the home and test again until the tester shows that the power is off. Alter the switch plate.
Position a stepladder beneath the light fixture. Eliminate the current lighting fixture’s globe and lights, then loosen the mounting screws and then pull down the fixture. Remove the wire nuts that connect the fixture’s wiring, and set the fixture aside.
Loosen the mounting screws that hold the junction box into the ceiling joist or drywall, and pull the junction box out of the hole at the ceiling.
Insert a ceiling fan brace into the hole at the ceiling and position the brace perpendicular to the adjacent joists using the arm of this brace centered over the junction box hole. Rotate the arm of this brace by hand to tighten the brace between the joists, then tighten it one rotation further with an adjustable wrench.
Place the mounting clip over the brace and then insert the electrical cable through the cable clamp of this matching junction box. Align the box using the clip’s mounting bolts, and tighten the nuts to ensure the junction box into the brace.
Mount the new light fixture mounting bracket into the junction box using the supplied screws. Then hang the fixture on the mounting bracket according to the instructions included with the lighting kit.
Connect the black cable from the junction box to all of the black wires in the fixture using a wire nut. Combine all of the white wires in similar fashion. Combine the bare wire in the junction box to the green grounding screw on the mounting bracket or into the green wire from the fixture using a wire nut.
Increase the canopy or cap over the junction box and then tighten the cover to place following the light’s mounting instructions. Put in the light bulbs at the receptacles, then mount the globe or diffuser over the lighting (if so equipped).
Turn on the circuit breaker and then test the lighting.
