Lumen Is a Body Heat Activated Flashlight

The science behind it might be confusing, but using the Lumen body heat activated flashlight is not. All you have to do to engage the 5mm Cree LED is touch your finger to the black Thermoelectric Generator with a picture of a fingerprint on it. Using the TEG module, a voltage converter and a super capacitor, Lumen uses your wasted body heat instead of batteries to illuminate anything around you. Housed in an aluminum or titanium case that doubles as a radiator, and available with a tritium vial so you can find it in the dark, Lumen is the perfect addition to any EDC if you’re the kind of guy that doesn’t need the brightest light on the market.
