Here are my lamps now. It is copper piping soldered together. I used the switch from my previous post. It is screwed into a brass pipe reducer which screws into a copper pipe fitting. The top of the switch is covered with a 3/4 copper end cap which sits on the plastic switch knob. I had to use some silicon tubing to in between to have a tight fit of the copper cap on the switch knob. The faucet handle is bolted to the copper cap which I had to drill a hole in.
The beer bottles are open at the bottom. I found them at Tuesday Morning. They were originally to be used with candle lights. A six pack for around $20. The lamp socket is the rubber out door socket from Home Depot and the bulbs are 25 watt bulbs which just fit inside the bottle.
To hold the bottle a found a conduit adapter at home depot. 1/2 copper pipe on one end and beer bottle at the other end:

Each of these dual lamps cost me about $45 dollars on material.
One thing which went wrong on my first built: When I cut the copper pipe with with a pipe cutter I did not realize that a sharp edge had built up INSIDE the pipe. After I had soldered everything together I could not pull the cables through the pipes. They just stuck on the sharp edges. Plus the insulation would have been damaged.
So for the second and final built I smoothed out the edges of the cooper pipe with my Dremel before I soldered the pieces together. Then pulling through the cables was no problem. Plus no danger of shortage because of damaged insulation.
