You know, the best lighting is the kind that you can adjust, make brighter or dimmer, not simply turn on or off. But the fact is, you can make practically any lamp into a three-way lamp simply by changing a socket. It's simple. Let me show you how.
Start by unplugging the lamp, unscrewing the bulb and removing the harp or bracket that holds the lampshade. To remove the socket itself, look for the word, press on the side. Push on that with your thumb and pop it off. Loosen the terminal screws and remove the wires from the old socket. Then attach the wires to the terminals on the new socket. Finally, replace the socket cover, reattach the shade bracket, screw in the bulb and replace the shade.
Plug the lamp back in and now you've got lighting for just about any mood or occasion.
