Thread the light bulb socket's power cord through the 12-inch pipe.
Spread glue around the edge and just inside the "bulb" end of the 12-inch pipe. Press the socket firmly into the glue.
Allow the glue to dry for at least three hours.
Thread the power cord into the up-facing hole of the five-way connector and out one of the other holes. Press the 12-inch pipe into the up-facing hole.
Thread the power cord through one of the 3-inch pipes. Press the pipe into the five-way connector where the cord comes out. Attach the coupler to the end of the 3-inch pipe.
Insert the remaining three 3-inch-long pipes into the remaining holes of the five-way connector. Cap each of these three to complete the lamp.
