Here's a DIY project: Grab a tree log, a light socket, and a clear light bulb. Drill out the log cavity down the middle and out the back for assembly of the lamp parts. (TIP: If your log isn't wide enough to support a round bulb, use a tubular bulb. It'll keep the light a safe distance from the wall and offer a more industrial look.) Mount and wire directly to an electrical box or invert the fixture and run the cord along the wall to an outlet down below.
