Shake Light, retail $24.50 (

Last updated 01-09-08

The Shake Light 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.

There is a magnet free inside the barrel, and one more magnet near the bezel (head) - 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.

This flashlight has three LEDs; each behind a positive (magnifying) lens - you can choose either one lit or all three lit, depending on your needs.

This flashlight comes in an aluminum body, not a plastic one like other "shake" flashlights.


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 60 seconds, or ~120 passages of the magnet through the coil. The magnet should pass through the coil approximately 2 times per second while you're charging the flashlight.

A pushbutton switch on the flashlight's barrel serves three functions:

Press & release it once to turn one LED on.

Press & release it again to turn it off.

Press & release it a third time to turn all three LEDs on.

Press & release it a fourth time to turn the flashlight off.

The sequence then repeats.

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

Because there are a number of moving mechanical parts inside this flashlight, the "smack test" really isn't that appropriate here.

Same with The Toilet Test.

This is also loaner, and I'm sure its owner will want it back with no dings in the bezel or desiccated rat pellets or yukky old toliet water in ther barrel. so I won't try to drown it in the cistern (toliet tank), bash it against a steel rod or against the concrete floor of a patio, let my housemate's kitty cats go to the litterbox on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a large claw hammer in order to smash it open to check it for candiosity, fire it from the cannonada (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout, with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses (nothing on this program gets bashed open to check for candiosity; all tests are performed with scanner-type noncontact devices!); and the cannonada is only used to shoot piņatas to piņata parties away from picturesque Piņata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a "keeper" flashlight might have to have performed on it. So this section of the web page will be significantly more bare than this section of the web page on a page about a flashlight that was sent for me to retain.

The metal body is knurled (texturised) for grip; it feels good & substantial in the hand.

I confirmed that there is a real magnet inside by holding the flashlight near a CRT boob tube computer monitor and noting discoration of the screen which increased as I moved the flashlight closer and dissipated as I pulled the flashlight away.

Test sample was loaned to me by a website viewer and was received on the afternoon of 01-08-08.

Product was made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.

UPDATE: 00-00-00

Reasonably durable construction
Never, ever have to buy batteries or bulbs for it

Charging (shaking) can resemble a "spanking the monkey" motion to some observers
