Tiffany lamps are ornate, colourful and collected by many people. Many styles, shapes and sizes are available, from tiny vanity lamps to large hanging lamps. Hanging a Tiffany lamp is not much different than hanging any other lamp fixture, but be careful and always handle your Tiffany lamps (especially the shades) with care to prevent cracks or breaks.
Turn off the main power to the room you're working in to ensure safety.
Unscrew the screw in the old fixture's canopy, using a flathead screwdriver. Pull the canopy down from the ceiling.
Unscrew the screws attaching the crossbar to the electrical box. Remove the old fixture from the ceiling.
Disconnect any of the wires that have been connected from the old fixture to the electrical box.
Wrap the bottom of a copper wire around your ground screw, clockwise. Fit the screw into the electrical box's threaded hole and tighten the screw in the hole. This creates your ground wire.
Pull up your Tiffany light fixture to the ceiling. Pull the canopy up to the ceiling and align it with the crossbar. Adjust the length of the lamp's pipe until 3/8 inch of the threads on the screw collar loop extends through the canopy. Lock the threaded pipe in this position by tightening the locknut that came with the lamp against the crossbar, using your hands.
Bring all of the wires to one side of the crossbar so they are not in your way. Screw the crossbar back into the electrical box, using a flathead screwdriver.
Connect the Tiffany white wire (neutral) into the white wire (neutral) of the electrical box.
Fold all of the wires inside the box. Raise the canopy to the ceiling and over the threaded support. Use the lamp's decorative nut to screw the canopy into the threaded support.
Turn the power back on to the room.
