The high precision dynamo version of the 5 inch forever flashlight has a higher quality dynamo which requires less shaking for prolonged use. The greatest dynamo flashlight to use anytime you need at home in the car in your boat or storm emergency kit. The forever flashlight is always ready - even if you haven't used or checked it for ages! The forever flashlight uses no batteries or bulbs instead it uses Faraday's Principle of Induction and a bright LED to produce light without batteries. It really pays for itself very quickly by saving you the cost of the batteries required to keep a standard flashlight in working order. Visible for up to one mile - even through fog smoke and rain! Similar in design to image shown.
