I found something similar to this at Orchard, except that mine has a two-light setup so you can adjust the brightness. Orchard's site is being an asshole, though, and I can't find it there.
Like the pictured one, it's only 5 bucks, and has both a foldaway hook and a p. strong magnet on the back, so I can put it up pretty much anywhere. And it's bright as hell. I don't know how I got along without it. The flourescent lights in my garage failed in rapid succession at one point, and it took me awhile to fix them; in the meantime, I was able to use this tiny light to light up the whole garage when I needed to.
