You could make your own lamp! It's pretty easy because lamp parts are standardized.

Step 1: Feed the stripped end of a lamp cord through a threaded lamp rod of whatever length you want

Step 2: Open a lamp socket and use the screw terminals inside it to attach the lamp cord to the lamp socket. Be sure to put all the parts back as they came, and snap the top half into the bottom half so it stays secure.

Step 3: Screw the lamp socket onto the end of the threaded lamp rod

That will give you all the necessary parts of a basic lamp. Then it is up to you to decide what you want the lamp's body and base to look like or if you want to position it so the lamp socket is facing some direction other than up.
