I picked me up one of these little lanterns the other day:

I first saw it at an REI store. Nifty little thing. Has a magnetic base and a pop out snap-hook for attaching to things. The frosted lens makes it a good glare-free small area light. It's not super bright, it's not super efficient, it's just a neat little middle of the road small area light, about 4 inches tall. The construction quality is very good. And it's cheap!
