Hanging a lamp shade is a good way to bring temporary overhead light to an area of a room where no fixtures exist. This might be a reading nook, next to a bed or even over a changing table in a newborn's room. This type of lamp is inexpensive and portable. If your needs change, you can easily move the lamp from room to room in a matter of minutes.
Thread the ends of the lamp cord onto the chain and weave it through the chain.
Insert the cord through the retaining nut and the top of the lampshade. Thread the wires through the threaded pipe and into the socket. Wrap the wire ends into the wire connectors on either side and screw tight. Press the socket together; this covers the ends of the wires.
Slide the spider frame of the lamp down over the threaded pipe and screw the retaining nut to hold the lamp in place. Add a light bulb in the socket. Set your lamp aside.
Screw a tea hook into the ceiling centred above where you want the lamp to hang. Hook the lamp chain onto the tea hook at the height you desire. Swag the chain toward the wall and the nearest outlet.
Screw a second tea hook into the ceiling to catch the swag of chain and cord. The wire should fall straight down to plug into the outlet. There should be an inline switch along the wire 4 feet above the floor.
You can add a lampshade over an existing glass fixture if the fixture is hanging on a central rod. Cut a slot in the spider washer of the lampshade wide enough to slide over the rod. Remove the glass shade and slide the lampshade into position, clean and replace the glass shade or use a diffuser to hide the bulbs from below.
Always turn off the power when working on hard-wired electrical fixtures to prevent accidental electric shocks.
