Goose Neck Light

My wife wanted a light that was absurdly expensive ($75/EA!). I didn't thing it was worth it so I made my own. I had to purchase a cheap light fixture to get the bulb base and I recycled the base (See link below). I went to install it this paste weekend but there is a shortage of junction boxes in Massachusetts so I could not install.
