There are two main things that go wrong with flashlights: the batteries die, or the bulbs break. Our Illuminator Wind-up LED Flashlight solves both problems by combining wind-up technology with the reliability of unbreakable, white LEDs. Wind up the Illuminator for 60 seconds for up to one hour's worth of light. The shape is easy to hold while you wind it and charge the built-in Lithium battery. A single button lets you choose between two brightness levels. Available in Silver and Red. Best for the money. Weight: 6.1 oz. Size: 5.5" L x 1.75" H x 2.25" W.
