You never know when or even how you'll need light, so the Gorillatorch Switchback covers most (if not all) of your bases. Ingeniously switching between a lantern and a headlamp, it can be used both personally and socially.
Not only that, the Gorillatorch Switchback also features the company's signature spider legs so that it can wrap it around pretty much anything. Comprised of five LEDs, it is adjustable from 5 to 130 lumens. Priced at $60, it is available online at Joby.
