Step 4: Lighting:
This sconce is wired with a basic pull-chain light socket* and lit with a 40 watt appliance bulb. An elbow made from brass tubes and couplings was attached to the base of the socket and bolted to the wall plate. The plate was then screwed directly onto the turtle shell.
For hanging: Eye screws and picture frame wire was affixed to the wall plate. Ta DA... all finished!
*Pre-wired sockets (Lamp kits) can be purchased at hardware and craft stores. DIYers can wire a light bulb socket in a few minutes and probably save money. Check out this easy step-by-step Instructable: How To Wire a Light Bulb Socket and examine the last picture for additional clarity.
