This LED USB Rechargeable Book Light turns late-night page-turns into a no-squint affair, clamping tight onto your novel or tablet with nine tweaks on tap—three brightness steps and three color temps—to match whatever mood or margin you're working with. It throws a tight beam right where you need it, so no one's getting woken by your midnight mystery binge.

Bend the arm a full 315° or swing it 90° side to side for that just-right angle without the hassle, and the USB charge keeps it going strong, cutting blue light with a warm amber tint to save your peepers from the strain. Slim enough to double as a page holder in your pocket, it's a road-trip staple for planes or hotel lamps that just don't cut it.
