Note: This is a very basic tutorial that worked for these lamps. The exact steps can vary depending on the type of lamp you have and the type of socket you’re using.
1. Buy your supplies. You can do this at a big box store, your local hardware store, or you can order supplies online. You’ll need a cord kit (or you can order wire and put your own plug on the end), a socket (I ordered one with a push through switch), and some parts to assemble the lamp. Typically the socket will screw onto a hollow piece of threaded pipe called a nipple. And you’ll need a washer and nut to hold the nipple in place and keep everything snug.

Many of the parts — the nipple, washer, nut, and harp, for example — you should be able to salvage when you take your lamp apart. But replace anything that’s rusty or corroded.

2. Unplug the lamp. Very important. Continue reading
