Body Heat-Powered Flashlights

The Lumen Flashlight Doesn't Require Batteries or Chargers

The Luman flashlight is a finger-sizedi llumination device that is equipped with a surprisingly small thermoelectric generator that powers up a single abut extremely bright 5-mm Cree LED light.

This flashlight enables you to find objects, navigate and read in the dark. The best part is that it works by harnessing your body heat, so it's eco-friendly.

This type of illumination technology has previously been to extend the battery life of small devices, and gained much attention when a Canadian high school student used it to create a working prototype of a body heat-powered flashlight. However what's exciting and unique about the Lumen flashlight is that it marks the first time that this sort of technology is being made readily available to the wider public as an attainable consumer electronics product.
