Do not stop at the walls when you are redecorating your room. Install a new flush mount ceiling light to complete the room design. A wide variety of flush mount light fixtures are available to obtain the look you want for your room. Change that old square glass shade flush mount fixture to something that matches the decor. You do not need prior electrical knowledge to install a flush mount ceiling light on your own.
Shut off the electricity to the flush mount light fixture location. To do this, you must turn off the breaker at the main service panel.
Climb a stepladder to reach the ceiling electrical box. Identify the hot, neutral and ground wire inside the box. The hot wire has black insulation covering the copper conductor, the neutral wire has white insulation and the ground wire has no insulation covering it.
Attach the mounting strap to the box in the ceiling. The mounting strap has several holes to facilitate the mounting of the flush mount canopy to the ceiling. Use the two outlet box screws, provided with the mounting hardware, to secure the strap to the screw hole flanges on the electrical box. Wrap the bare ground wire inside the box around the green screw on the strap, but do not tighten the screw.
Connect the flush mount ceiling light canopy to the electrical wiring inside the electrical box. Twist the white fixture wire to the white electrical box wire using an orange wire connector. Twist the black wire from the box to the black fixture wire with another orange connector. Wrap the green fixture wire around the green screw on the strap and tighten the green screw.
Thread the two mounting screws through the screw holes in the fixture canopy. Screw them into the mounting strap, securing the canopy against the ceiling.
Screw the light bulbs into the flush mount light bulb sockets. Attach the flush mount fixture shade to the canopy. Depending on the style of the fixture, you either tighten the screws threaded through the canopy to hold the shade, or twist a finial onto the connector at the bottom of the shade. Turn the electricity back on.
