Disconnect the lighting circuit at the main breaker panel by turning off the circuit breaker. Confirm the breaker is off and the power has been disconnected, using a two-prong electrical tester. Locate the black wire inside the ceiling junction box. Touch one prong of the tester to the black wire and the other prong to any metal on the junction box. The tester should not light if the power has been disconnected correctly.
Attach the fixture crossbar to the electrical box in the ceiling. The fixture crossbar is a flat piece of metal 4 inches long and 1 inch wide with several openings cut into it. The bar attaches to the box with screws provided with your light fixture and a screwdriver.
Wire the base of the flush mount light. With a partner holding the base, connect the black wires from the light fixture to the black wire from the junction box, using an orange wire connector. Repeat this connection for the white wire from the fixture and the white wire from the junction box. Connect the bare copper wire from the junction box to the green ground wire on the light fixture with an orange wire connector.
Attach the flush mount light base to the crossbar, using screws from the light fixture’s mounting hardware.
Install light bulbs and the light shade according to the manufacturer's directions.
Turn the lighting circuit back on by turning the breaker on at the main electrical panel.
