Sometimes the simplest and cheapest items turn out to work the best. The Flex Neck light is simple and elegant, with just a clip and a flexible neck with a light at the end. There are a few tweaks that make this light special, however. The main benefit is its adaptability to multiple types and sizes of books. This is one of the few lights around that will work for anything from mass-market paperbacks to a 1,000-page hardback biography. It just clips onto the cover of whatever you are reading, with no cords or battery packs.
The other advantage is that this is the best of the ten featured here for packing light. A hole in the clip part holds the circular light part, allowing the whole thing to fold down into something the size of an Oreo cookie. The one drawback is that the small and lightweight battery is something you would normally find in a watch or calculator, so you can’t just pop in a standard battery you have lying around the house when this one dies.
