Arc-AAA Turquoise, retail $TBA*

Last updated 02-02-08

The Arc AAA Turquoise is a very tiny, single "AAA" cell LED flashlight, very similar to the original Arc AAA but with a few visible differences. Smaller than a Mag Solitaire, this is easily the smallest and brightest single cell turquoise LED flashlight in existence today (as of 01-07-08). A miniature step-up power converter inside the tiny head makes it possible to run a 3.2 to 3.8 volt blue-green LED with only a single 1.5 volt AAA cell.
The easy-grip body is composed entirely of hard anodized aircraft aluminum, and is, for all intents and purposes, indestructible. The bezel (head) isn't perfectly cylindrical, but has a slight rounded shape to it.

As for the easily visible differences, one is that the bezel is slightly rounded (barrel-shaped), rather than being perfectly cylindrical (to make the flashlight easier to insert into pockets with tight openings).

* This is said to be a prototype; it may not be readily available to the general public as of this writing (01-07-08).


To use this miniature marvel, you will first want to feed it with a single "AAA" cell if it was not already installed in the flashlight when you received it (it should not be; though one *IS* included!).

Getting light is as easy as turning the head clockwise (as if tightening it) until it lights up; turn it the other way to plunge yourself back in darkness.

The Arc AAA Turquoise comes with a small split ring attached to the tail. This is meant to be attached to larger keyrings, like what your house & car keys are probably already on; and for attachment to a lanyard to hang the Arc AAA Turquoise around your neck or around a nail or tree branch.

The knurled surface makes the light easy to grip and use.

To get your Arc AAA Turquoise powered up and ready to face the world, unscrew the head until it comes off (don't worry about losing parts or bulbs), and drop the included Duracell AAA cell in so the button end faces up. Screw the head back on, and you're finished.

A foam gasket affixed to the bottom of the inside of the head prevents that annoying rattling sound from the battery moving around inside when the unit is turned off.

Advertised runtime is no less than five hours on a Duracell brand alkaline cell.
The company that makes this flashlight tends not to lie or exaggerate, so this runtime value should be reasonably accurate at absolute minimum.

Due to the way the product was constructed, I am not able to furnish a current usage measurement for you.

This is a 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.

O wait...I was, however, given explicit written consent (not just implied oral consent) to perform "The Toliet Test" on it.

Here's proof that I really performed "The Toliet Test" on it.
After immersing it in the cistern for one minute in ~12" of water at 65°F (18.3°C), I dried the outside off with some bungwipe, examined the insides, and found no water in it. Being submersible to 100 feet though, this was no real surprise.

This test was conducted in the *CLEAN* part of the commode, not the bowl, So this flashlight did not needed to be washed, scrubbed, disinfected, or otherwise sanitised after this test.

There is knurling (diamond-shaped cross-hatched texturising) on the barrel and on the bezel, so retention (the ability to hold onto the flashlight when your hands are cold, wet, or oily) shouldn't be much of an issue.

The bezel (head) of the Arc AAA Turquoise is slightly rounded (barrel-shaped as opposed to being perfectly cylindrical); as a result, some users may find it a little easier to place in a pocket, especially the watch pocket of jeans, which is typically has a tight top to it.

A foam gasket is affixed to the underside of the bezel (head); this helps to prevent battery rattle when the unit is shaken, struck against something else, or dropped.

Test sample was loaned to me by a Candlepower Forums member, and was received at 2:51pm PST on 01-07-08.

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

UPDATE: 01-30-08
Product has been packaged for return to its owner; therefore, that dreadful "" icon will be added next to its listings on this website. My electric wheelchair blew a tire (or "tyre" if you prefer) on the way to the UPS store this morning, so it won't actually get shipped until tomorrow (01-31-08) at the earliest.

UPDATE: 02-02-08
Product has been shipped back to the person who was gracious enough to loan it to me, so I no longer have it at my disposal.
