Circular fluorescent light fixture
When it comes time to update your bathroom or kitchen lighting, you may think about installing a circular fluorescent light fixture or two. These smaller versions of the traditional rectangular fluorescent take up a lot less room and look quite stylish, too. Replacing a regular light fixture with a fluorescent can also save you money because fluorescent lights are a lot more energy-efficient.
Put on gloves and eye protection. Lay down some dropcloths under the work area.
Turn off the power to the room you are working in. Set up a ladder.
Remove the old light fixture cover by loosening up the nut. Do this by hand or use a small pair of pliers if necessary. Remove the light bulbs.
Remove the light fixture mounting base with a screwdriver. Let the fixture hang loose. Hold an electrical tester up to the wire connections to make sure the power is really off.
Disconnect the wires from the wire nuts. Notice where the wires go, so you can reconnect them later. Remove the old light fixture base.
Hook up the mounting plate from the new fixture, just like you did when you removed the old. Make sure your wires are connected properly.
Attach the new mounting plate to the ceiling, using the screwdriver and screws. The screws mount through the mounting base and up into the electrical box that's in the ceiling.
Hook up the circular fluorescent bulb by plugging the male connector on the bulb into the female receptor in the light fixture housing. Clip the bulb in place.
Install the light cover by screwing it on clockwise. Some covers are held on by screws.
Turn on the power and check to see if the light fixture works properly.
Since circular fluorescent light fixtures are usually quite small, you may have to do some painting on your ceiling because portions of it will now be exposed.
