Having a reasonably un/healthy obsession with industria and vintage industrial decor, I found it hard to stop thinking about the Kozo lamps by Anat & David Shefa. I just had to have one!!! But budgets being budgets and me being me, there would never have been any other way. I had to just make them myself. So I went down to the local hardware store and grabbed:

5x - 15mm elbows
4x - 15mm male/male spacers
3x - 15mm tee pieces
2x - 15mm x 100mm tube
1x - 15mm x 200mm tube
1x - 12mm x 400mm tube
1x - 15mm female to 20mm female reducer
1x - 20mm male to 25mm male reducer
1x - 25mm elbow
1x - 25mm male to 20mm female reducer

knead it epoxy putty

lamp for parts (i used the cheapest halogen i could buy)
make sure the fitting you're pulling out of the lamp will fit into the elbow to the lamp head

all the assembly is pretty straight forward.
i won't get into all the wiring details. they're pretty straight forward but if you don't know how to do it, i'm not getting blamed when you zap yourself using my instructions!
i had to cut down the length of the 25mm male to 20mm female reducer with an angle grinder so that the fitting would sit nice and snug behind it, all held in place in the big elbow with the knead it epoxy putty.

since photographing this i have added a silver toggle switch in the middle t piece and changed the cord to a silver cloth covered number from sundialwire as white plastic doesn't really do it for me.

i put together a time lapse video of the build at - http://www.youtube.com/watch?v=oZ2_7CYdlz4
