I needed some sort of a really bright light for my work space. So I hacked a 16x Cree spotlight I had. I never used it much because it was have and took an insane amount of power (3 amps almost constant). So I hacked it to run off wall power instead and put it on my adjustable arm. I now have a blinding light ;)
