Forever Dynamo Flashlight |
 |
| This flashlight uses no batteries or bulbs. Instead it uses Faraday's Principle of Induction and a bright LED to produce light. No batteries required at all. The light is shaken for about 30 seconds to recharge a capacitor and it will then provide about 4 minutes of light. As the light is shaken, a magnet passes through a metal coil inducing electric current into the coil which in turn charges the capacitor.No empty batteries and no light bulb to replace. Product Dimension: 9 1/2"" x 1 1/2"". |
