This 0.5 watt LED flashlight, sold by Advancedmart, does not have a formal name that I know of, so I'll just call it a "flashlight" on this web page.

It comes in an aluminum body, has an as-of-yet unknown brand 0.5 watt LED at the bottom of a smooth reflector, uses a single AA cell in its barrel, and has a pushbutton on/off switch on its tailcap.

The battery (one AA cell) may or may not be included; so be sure to have one on hand just in case.


To use this flashlight, feed it first (see directly below), and then you can go to town.

Press the button on the tailcap until it clicks and then release it to turn the flashlight on.
Press the button on the tailcap until it clicks and then release it to turn the flashlight off.
Yes, it really is as easy as that.

There is no momentary or signalling mode available when the flashlight is off, however, you can blink the flashlight while it is on by partially depressing the button. If you don't mind the backward or reverse feeling of this, you can blink the flashlight this way.

To change the battery, unscrew and remove the tailcap, throw it to the ground, and stomp on it with old or used bowling shoes...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the used AA cell out of the barrel and into your hand, and dispose of or recycle it as you see fit.

Insert a new AA cell into the barrel, button-end (+) positive first.

Sscrew the tailcap firmly back on.
Aren't you glad you didn't stomp on that tailcap now?

Current usage measures 343mA on my DMM's 400mA scale.

The flashlight appears to be reasonably sturdy. Ordinary flashlight accidents should not be enough to do it in. I administered the smack test on it (ten whacks against the corner of a concrete stair; five whacks against the side of the tailcap and five whacks against the side of the bezel), and found the expected damage. There is some very minor gouging on the side of the bezel where it was struck. No optical or electrical malfunctions were detected.

I tried to scratch through the finish with the blade of a Swiss army knife, and was successful. This shows it has a type II anodized finish on it at best.
Would I really try to cut up a brand spanken new flashlight?
You bet your sweet patootie I would, if it's in the name of science.

This flashlight is splash- and weather-resistant at absolute minimum, but it is not submersible. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of albino wolf pee, slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, 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 the water out of the barrel 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 or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your flashlight to smell like seashells or urine when you go to use it next. Besides, salt (from seawater or pee) can't be very good for the insides.

The flashlight has knurling (cross-hatch texturising) on most of its barrel and a band of knurling on the tailcap, so retention (the ability to hold onto the flashlight when your hands are cold, wet, or oily) shouldn't be much of an issue.

I don't normally provide beam photographs on a wall with non-Luxeon flashlights, but this flashlight is bright enough for this type of picture.
