About Shaker Flashlight

A flashlight or torch is basically a portable, hand-held electronic spotlight. The Shaker Flashlight is a dual-powered flashlight that functions on alternate power, i.e., either battery power or Faraday's Principle of Magnetic Induction. It provides one with over twelve hours of constant useable battery-powered light. Once the batteries run out, it switches to the Shake and Shine function. The Shaker Flashlight's Shake and Shine function utilizes Faraday's Principle of Magnetic Induction which states that 'The electromotive force induced in an electric circuit always acts in such a direction that the current it drives around the circuit opposes the change in magnetic flux which produces the electromotive force.' Therefore, as the Shaker Flashlight is shaken, a magnet which passes through the metal coil creates voltage in the coil and produces electricity. Shaking the flashlight for 10-15 minutes can produce as much electricity as to keep the flashlight functional for 2-3 minutes. The batteries used are CR 2032 lithium which give the flashlight over twelve hours of constant power. The Shaker Flashlight emits an ultra-bright white LED light. The Shaker Flashlight has no maintenance cost whatsoever. The ultra-powerful white light-beam is visible for over a mile. The LED bulb has the capacity to last for thousands of hours and does not burn out easily. The rugged ploy carbonate body ensures that the flashlight is sturdy even when handled roughly. The device weighs just 3.8 oz. All in all, the Shaker Flashlight is of immense use for all purposes such as home power failures, cars, as a camping accessory, for boating, or even plain emergencies.
