Eternaleds Keychain Flashlight, retail $ (Free*)

Last updated 09-05-10

This is a handsome, sleek & modern looking version of the white coin cell flashlight that's all the rage these days. The case is held together by six screws, and is the size and shape of those "flat" laser pointers that Sharper Image was promoting seven or eight years back and of the Stick of Gum laser pointer you can get now.

Inside you'll find a 5mm white LED and a single CR1220 lithium coin cell, and the light is activated by pressing the silver button near the front.

* Free, with purchase of $100 or more from their website.


This flashlight is ready to use right out of the package.

Pressing on the silver button and holding it down turns it on; letting go turns it off.

To change the battery, use a small phillips screwdriver (the #0 with the 1.6mm shaft diameter from my set of jeweler's screwdrivers worked well here) to unscrew and remove the six screws from the top of the flashlight. Set the screws aside - or if you're uncomfortable doing that because of their very small size, place them in a small teacup or saucer - they won't get lost too easily this way.

With the light on a desk, table, or other flat surface, carefully lift off & remove the upper half of the light's body, very gently place it on the floor, use your foot to slide it to the door leading downstairs, and very firmly kick it down the stairs so that the hungry, hungry piss ants will think it's something yummy for their little insect tummies, drag it to the nest, present it to the queen, who then finds it unpalatable so she just squats over it and goes potty on it and instructs the worker ants to do the same...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

In the rear half of the light's body, you'll see a lithium CR1220 coin cell in a circular compartment. Remove it, and dispose of or recycle it as you see fit.

Insert a new CR1220 cell into this compartment, orienting it so that its flat side (+) positive faces up.

Place the upper half of the light's body back on, and insert & tighten those six screws.

Aren't you glad you didn't kick the upper half of the flashlight down the stairs with all those hungry, hungry piss ants now?

This flashlight is made of plastic and it's fairly small, so I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of an outdoor patio, use a medium claw hammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (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 (located at Piņata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island {In the episode "Les Saves the Day...Again", Paulie Preztail says "Hey, ever wonder why this park's called 'Mount Erupto' anyway?", then Franklin Fizzlybear says "I think its an old native term. Means 'very safe.'"}), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights in sturdier plastic or metal bodies may have inflicted upon them.

It's thin and small, and will fit unobtrusively in a shirt or pants pocket if you remove the flat-sided split ring. You can also hang it from your keychain, or dangle it around your neck on a lanyard. It has a swivel attachment, so it won't get tangled up when you grab it and find you need to turn it around to push the button. I like swivels on things like this.

The LED is recessed in a special hosel (think of the LED sitting inside the screw-in part of a golf club head), and is therefore a bit less likely to become damaged, especially if the unit falls on the floor face-first.

The unit is *not* waterproof, but should be alright if you get caught in a rain shower and have to make a run for it. Do not drop this in a river, sink, pool, toilet, pet water bowl, or bathtub or you will end up having to take it apart and dry all those little pieces out.

This looks an awful lot like the Garrity Keychain Flashlight, so it would not at all surprise me ***AT ALL*** if they were made by the same manufacturer.

Beam photograph on the test target at 12".
Measures 17,950mcd on a Meterman LM631 light meter.
This is a surprisingly high intensity considering that this light uses just one cell (battery).

Test unit was sent to me by J.C. of Eternaleds on 09-05-08, and was received on the morning of 09-09-08.

Product was almost certainly 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.
