What's the best thing about clip-on lights, besides their low price? In a word: versatility. There are dozens of ways that a clip light can come in handy. For instance, if it's tough to see into the inner reaches of your bedroom closet, you can clamp a light like this one onto a shelf, and thanks to its adjustable gooseneck design, direct the light to wherever it's needed. Another option: Attached to a headboard, a clip light makes it easy to read in bed, not least because you can instantly adjust the fixture if you decide to roll over. Now that's luxury!
