The Diamond LED Shake Flashlight is a flashlight that never needs batteries or bulbs, and never needs to be plugged in either. So it will always work when you need it. The claim says "90 seconds of shaking provides 120 minutes of light".

There is a magnet free inside the barrel, and two more magnets - one at each end - to repel the large magnet when charging up the flashlight. So unless you shake the {vulgar term for feces} out of it, the central magnet should not hit the ends of the flashlight barrel.


After turning the flashlight off, hold it parallel to the ground and shake it back and forth (so the magnet passes back and forth through the coil) for 90 seconds, or 270 passages of the magnet through the coil. The magnet should pass through the coil approximately 3 times per second while you're charging the flashlight.

When you first receive the flashlight, it is possible you may need to shake it for 180 seconds; but after that, 90 seconds maximum ought to do the trick.

A sliding reed switch on the flashlight's barrel turns the LED on and off. As long as you can slide this switch, you can turn your flashlight on and off. This switch is impregnated with a glow-in-the-dark material, making it a bit easier to find after dark.

Remember, this flashlight uses powerful magnets, so you want to keep it at least 16" from such articles as TV sets, computers, computer monitors, computer diskettes, audio & video tapes, bank cards, and other items that should be kept away from magnets.

Because it uses magnets, you can use this flashlight as a compass, by hanging it vertically from a string or wire and the lanyard loop on its tail end.

Because this product does not use batteries, this section can be skipped.

This is not a flashlight that you carry around all the time, it's a flashlight that's most useful in emergencies or when you just can't get batteries. It would be good to use for changing that pesky fuse in the basement, finding other articles (like flashlights) in a power outage, and stuff like that. And if you can't get batteries for whatever reason, it will provide light without them and when other flashlights have long since quit working.

Because this flashlight uses a reed switch, there is no opening in the barrel, so it's water-resistant (submersible, actually) to an amazing 400 feet. So it will easily survive if it falls in the toilet, if you knock it into the tub, if you drop it in a river, pond, lake, shoreline; or if you throw it in the pool for the kids to go after if you're into that kind of thing.

Most of the LED light comes out the front; a little comes out the sides through the bottom of the LED and out through the platform it's mounted on. This lights up most of the plastic pieces inside the head, but in my opinion, not bright enough to be bothersome. One benefit here is that you can tell if you left the flashlight on when you set it face down on a shelf or other flat surface, even if that surface is flat black. Not that it matters much because this light does not need batteries, but it can be bothersome to some users.

This is a peak value; it will decrease as the capacitor is discharged.

Test unit was provided by Steve at www.flash-lights.com and was received on 11-10-04.

UPDATE: 11-11-04
I have received a couple of emails from people asking how long it lasts on one charge.
Once I have the time, I will run that test, and then everybody will see how long it runs per charge.
