Buy Cheap Shake Flashlight Magnetic Induction Bright LED Rechargeable Flash Light 
Buy Low Price From Here Now The Shake Flashlight uses no batteries or bulbs. Instead it uses Faraday's Principle of Magnetic Induction and a super bright LED to produce light without batteries. The flashlight is shaken for a few seconds to recharge an internal capacitor and it will then provide upto an amazing 10 minutes of light. Shake it longer for up to 30 minutes of constant light. How does this happen? As the flashlight is shaken, a magnet passes through a metal coil which, when you shake, "induces" voltage in the coil generating electricity.
During prolonged use it can be shaken for 10-15 seconds for every 2 to 3 minutes of super bright light. The light requires no maintenance so it can be left in your home or car for a longtime but will still be ready to produce light. The bright LED will last for thousands of hours and does not burn-out like a typical lightbulb - it should never need replacement. Great for home, car, camper, boat, or emergencies. Imagine exploring without the fear of ever running out of light. No need to worry about light if your car dies during a dark and stormy night. You'll be in great shape even if you have to signal for help in the pouring rain because it's 100% waterproof. The light it emits is twice as bright as an ordinary flashlight and is visible for up to one mile. This is a flashlight that never needs batteries, replacement parts or even bulbs for that matter. Now that's peace of mind.

"Horrible" 2009-06-14
By John (Boston, MA)
This thing outputs so little light it's terrifying. The light coming out of my cell phone's display is much brighter than the few nanolumens this thing produces with vigorous shaking.
"Reed switch doesn't work, the flashlight is inoperable." 2009-01-07
By Green Girl (Houston, TX)
I am helping my son with an electromagnetic induction science fair project and have studied extensively the requirements for these types of flashlights to operate. This flashlight is better than the 'fake' shake flashlight we'd previously ordered for $2.35 at amazon.com, because it actually uses a real NIB magnet and appropriate circuitry. However, the reed switch (which uses a small magnet to connect the capacitor's stored potential to the LED)doesn't work. Thus, the LED won't light. I'm very disappointed with this purchase. There are genuienly amazing shake flashlights that, both in function and design are truly brilliant devices, but they cost a lot more than this flashlight, so it seems that the old saying, "you get what you pay for", is proven true, once again.

While our flashlight seems to work, I can't help but notice that it has a lithium button battery, which might explain its function. The "Magnet" is actually a piece of lead. So how does it really work? Shaking it definatly increases the brightness, but it seems it is assisting the magnet.

This is a very trustworthy flashlight. Buy shaking it back and forth several times, it gets charged enough to use. It is wonderful if you don't want to be dependent on batteries. When you are in a emergency situation, you cant depend on how much energy is left in your batteries, and when you have to have light, this flashlight this one you can depend on when you need to. I have two.

It wasn't exactly what I was expecting when I received it. It's quite a bit smaller than what I was imagining. But it works and we will use it.
