I went looking for my ancient book light a few weeks ago, only to find it damaged and completely useless in my rare hour of need. It was one of those brightly colored, clip-on contraptions with an oversized spherical light that always reminded me of a big googly eye. Anyway, I started browsing possible replacements online and discovered that there is a whole world of cool book lights out there I knew nothing about.
