Dynamo® Hand-Powered Flashlight - Lee Valley Tools

by sbrothier
This is one flashlight that will never cause you to worry about batteries going dead, leaking into the casing or being affected by heat or cold. It works based on the dynamo principle that was first discovered by Michael Faraday in 1831.
