The Ultra-Bright L.E.D. Keychain Light is a small LED flashlight, designed to slip into your pocket or attach to a keychain with the included medium split ring.

It comes in a plastic body (blue with matte silver trim or all matte silver), has a 5mm white LED on the end to produce its light, and feeds from a pair of included CR1220 lithium coin cells.

This isn't a "Suuuper-DEE-DOOOOOOper" (as Barney the Purple Toliet Dinosaur might say) flashlight, but it's perfectly adequate for general use, and for showing off that "newfangled" LED technology.

* Not found on the Big Lots website; so this URL simply leads to their front door.
Product comes in a package containing two units; so the actual "per-unit" cost was just $2.00.

The Ultra-Bright L.E.D. Keychain Light is ready to use right out of the pack.

Just squeeze and hold the silvery-grey button on the upper surface of the product for as long as you need light, and release pressure to turn it off.

There is no continuous or "hands-free" mode available in the Ultra-Bright L.E.D. Keychain Light; please do not look for or expect to find one.



To change the batteries when necessary, get a small phillips screwdriver (the #0 with a 2.0mm shaft diameter from my set of jeweller's screwdrivers did the trick here), unscrew & remove the six small screws from the top of the product, carry them outside, and chuck them as vigorously as you can into an open-pit zinc or antimony mine so that bulldozers and such bury them so that they become lost...O WAIT!!! YOU'LL NEED THOSE!!! So just set them aside instead. The screws are fairly small, so I can easily envision them falling into the carpet and later falling prey to the hungry, hungry vaccume cleaner as well as being thrown into a mine.

Using the tip of a knife blade, carefully pry out the used CR1220 lithium coin cell out of the rearmost chamber, and dispose of or recycle it as you see fit.

The cell in the frontmost chamber (closest to the LED) contains the LED lead and switch mechanism (NOTE HOW THEY ARE IN THERE NOW!!!); lift that away (the LED may come along for the ride here as well), and set that aside too. Using the tip of a knife blade, carefully pry out the used CR1220 lithium coin cell from this chamber, and as before, dispose of or recycle it as you see fit.

Insert one of the new CR1220 cells into the frontmost chamber, orienting it so that its flat-end (+) positive faces down.

Insert the other cell into the rearmost chamber so that its button-end (-) negative faces down.

Place the LED and switch mechanism over the frontmost cell *EXACTLY* how you found them - now do you see why I said "(NOTE HOW THEY ARE IN THERE NOW!!!)" earlier?

Place the light's halves back together, and insert & gently tighten up those screws, and there, you're finished.
Aren't you glad that you didn't huck those screws into the mine now?



The Ultra-Bright L.E.D. Keychain Light is very small and is made almost entirely out of plastic, so "The Smack Test" would not really be appropiate here.

That said, this flashlight appears quite durable, but I don't believe it is too water-resistant. When I had it apart to do the battery change, I did not see an O-ring between the case halves. When the LED-end was suctioned on, rather extreme leakage was detected. So water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside through the seam that runs all around the outside. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of laboratory rat pee, glasses of milk, slush piles, mud puddles, tubs, root beer floats, tiolet bowls, cisterns, sinks, cups of coffee, fishtanks, dog water dishes, old yucky wet mops, wall-mounted porcelain urinators, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in moderately bad weather.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater, got thrown into a glass of milk, if it fell in a root beer float, if it fell into a bowl of "soft-serv" ice cream, if somebody squirted a Massengill brand post-menstrual disposable douche or a Fleet brand disposable enema at it (and hit it with the douche or the enema), or if somebody or something got "pist off" at it and subsequently "pyst" on it, rinse the parts out with fresh water before setting them out to dry. You don't want your Ultra-Bright L.E.D. Keychain Light to smell like seaweed, sour milk, flowers, fresh butts, or rotten pee when you go to use it next. Besides, salt (from seawater, disposable douches, disposable enemas, or uranation), lactic acid (from moo juice), glycerol (from antifreeze), or sugar (from root beer & ice cream) can't be very good for the insides.

This appears to be a fairly well-constructed flashlight, provided you don't just beat the devil (or beat the {vulgar term for feces}, or beat the urine, or beat the living tweedle) out of it.
That is, it will definitely do what you purchased it to do - that is, provide light.

TEST NOTES:
Test units (they come in a package of two) were purchased at a Big Lots store in Federal Way WA. USA on 06-10-09.

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