Somebody had a bright idea when they came up with the Lightwedge. It's a reading light for books made out of a sheet of optical-grade (whatever that means) acrylic and illuminated by LEDs. The LEDs light the acrylic which in turn evenly lights the entire page you're reading. This seems like a better idea than traditional book lights, which tend to brightly light one spot of the page only.
You'll need four AAA batteries to power the thing, but they'll supposedly last a whopping 40 hours. That's probably enough time to read The Lord of the Rings several times over, even if you're a slllooowww rrreeeaaadddeeerr.
how. cool. is. this?
You can also buy a nightvision version of the Lightwedge, "perfect for sailors, astronomers and aviators." And just plain fun for everyone else! Both versions have two brightness settings. The nightvision version is $44.95, while the regular is $34.95 and a smaller, paperback model is $24.95.
