Last updated 04-23-06

The Luxeon I Tactical Light, model ALX-2512AA (hereinafter, just called a "flashlight"), is an LED flashlight that uses a Luxeon I LED and a total internal reflection optic to produce its beam.

It comes in an almost all-aluminum body, covered with a Type II anodizing for protection, has a rubbery pushbutton on the tailcap, and has two AA cells in its barrel to feed that LED with.

There is a DC-DC inverter in the bezel (head); this increases the 3 volts from the batteries to no less than the 3.6 volts that white LED needs.


To use the flashlight, install the included batteries first (see the "Feeding Time" section directly below), and then you can go to town.

Press the rubbery button on the tailcap firmly until it clicks and then release it to turn it on.

Press and release the button the same way again to turn the flashlight on back off.

For momentary or signalling operation, just partially depressing the button will do the trick here. Having a true momentary mode is (to the best of my knowledge) new for a suspected Nuwai product, and yes, I really do like it.

The flashlight comes with a wrist strap, already affixed to the unit's tailcap via a hole in the edge of the tailcap. This strap is large enough to go around the flashlight; you can use this strap to hang the flashlight from tree branches, water pipes, or other long thin objects with no readily accessible "end".

The flashlight comes with a nylon pouch/belt holster. The flashlight fits this holster bezel-up; a flap with velcro on it folds over the top and attaches to the body of the holster with a matching piece of velcro, so the flashlight doesn't just fall out. This holster fits belts up to 1.5" wide, and can be threaded through the belt. I do not own or use pants that require a belt however, so I cannot test this accessory in the manner in which it was intended to be used.

To change the batteries when necessary, unscrew and remove the tailcap, throw it in the garbage can, and empty the garbage can outside where the garbage man will see it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the two used AA cells into your hand, and dispose of or recycle them as you see fit.

Insert two new AA cells in the barrel, button-end (+) positive first. Screw the tailcap back on, and be done with it.
Aren't you glad you didn't throw away that tailcap now?

Current measures 521mA on my DMM's 4A scale.

This flashlight appears at least fairly durable, and it is. When I performed that terrible smack test on it (ten whacks against the corner of a concrete stair: 5 smacks against the side of the bezel and 5 smacks against the side of the tailcap), only the expected damage was found. There is some minor gouging on the sides of the bezel and tailcap where it was struck. No optical or electrical malfunctions were detected.

There is a clear Type II anodized finish over all of the exposed aluminum; this should help keep the flashlight looking newer for longer, even if it goes up against coins, keys, or other flashlights.

The flashlight appears to be weather- and water-resistant at the very least. When I removed the tailcap, relieved the barrel of its batteries, and then performed that dreadful suction test, no leakage was detected. So if it fell into shallow water, just shake it off and keep going. And you need not be concerned about using it in rain or snow. And if it fell next to the mailbox and the dog pissed on it, just take the garden hose to it or douche it off under the faucet...good as new! Being water- and pee-resistant is fairly new for a suspected Nuwai product, and makes an already good product even better.

The light produced is a pure white, with no obvious yellow, blue, purple, or "rotten cat urine green" tints to it.

Test unit of this flashlight and 17 other products were sent by A.L. of Amondotech and were received late in the morning of 07-11-05.

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.
