Intro: Adjustable Lamp
I rigged-up a low level lamp from the ceiling for photographing things (like Lego).
Originally I used the bayonet fitting from an old compact fluorescent lamp to plug into a light-fitting, and hung the lamp from a beam.
Today I modified the lamp by suspending it from an old steel tape measure reel with some rather hairy string.
It will position up and down over about 2 feet.
