Question: To add a light inside a lamp.

  Options: 
 A. Get wire with a plug, and chain, and feed the chain on. Then put on a washer -this should be decently big, and this is how the shade part will be attached. Then tape the wire to the socket, and screw in the bulb. CFLs don't get very hot, so go with one of those.
