================================================
These amazing LED Forever Flashlights use the Faraday Principle of
Electromagnetic Energy eliminating the need for replacement bulbs
or batteries. Just as in a car generator, when wire moves though a
magnetic field, energy is created. By shaking the flashlight for
15-30 seconds enough energy is created and stored in the capacitor
to shine the super bright LED for 5 minutes of continuous light.
