It's getting to be too dark to snap quick photos when I get home from work these days, so I splurged and got me a $1 LED desk lamp from Dollar Tree. I'm actually pretty surprised at the quality; if nothing else it makes an excellent task light. Bulbs cannot be replaced; whole unit is a throwaway when it dies, but again it's a dollar.
Some sample photos with the random crap on my desk:
It's no $500 setup, but figured I should pass it along for anyone who might be interested. It plugs into the wall and advertises a life of 36,000 hours.
