Shut off electricity to the room you will be working in. To remove the old light fixture, use a flat screwdriver to remove the cover of the old fixture and the trim around the light. Remove the light bulb.
Remove the ceiling panels from a paneled ceiling, or raise the upper section of the old fixture in ceilings without paneling. Remove the junction box and the upper section of the light fixture. In the junction box, take off the wire connectors and separate the fixture wires from the house wires. Keep the house wires within reach to hook up to the new fixture.
Measure the hole left in the ceiling by the old fixture, using a tape measure, so you’ll know what size fixture to buy. Choose a fixture a bit larger than the hole. If your new fixture is a lot larger than the hole in the ceiling, make the hole a bit bigger.
Install the new fixture, beginning with the junction box and the top element. Use the wire stripper to splice together the fixture wires and the house wires, and then cap off the wires with the wire connectors that twist on. Connect the junction box to the ceiling joist, according to any local code regulations.
Install the bottom portion of the new fixture according to the instructions that came with your replacement light. Put the light bulb back in place, and put back in place any trim and glass that came with the fixture.

- When choosing a square recessed lighting fixture, don’t assume a larger fixture gives off more light. The lamp determines the amount of light, and the same lamp will fit into different fixture sizes.
