Last updated 06-12-05

The Advancemart 0.5 watt LED flashlight is a small LED flashlight that comes in a chromed brass body, features a 0.5 watt white LED at the bottom of a mirror-smooth reflector, and feeds from a single 3 volt CR2 lithium cell. This cell is considerably smaller than a CR123A cell; as a result, this flashlight is also smaller than one using a CR123A cell.


The flashlight is ready to use right away as soon as you remove it from the package and holster.

Firmly press the button on the tailcap until it clicks and then release it to turn the flashlight on.
Do the same thing to turn the flashlight off.

There is no momentary or signalling mode available when the flashlight is off; however, you can blink the flashlight when it is on by depressing the tailcap less firmly (before it clicks) and holding it that way for as long as you need the flashlight off.
If you don't mind the backward or reverse action, you can blink the flashlight this way if desired.

This flashlight comes with a nylon belt holster that has a loop that will fit belts up to 1.5" wide. The flashlight fits in the holster bezel (head)-down, and has a hook and loop fastener on the flap that allows the flap to be closed over the flashlight. I do not own or use pants that require a belt though, so I cannot test this accessory in the manner in which it was intended to be used.

To change the battery, unscrew and remove the tailcap, and set it aside.

Slide the used CR2 cell out of the barrel, and dispose of or recycle it as you see fit.

Insert a new CR2 cell in the barrel, button-end (+) positive first, and screw the tailcap back on.

Current consumption measures 287.1mA 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 denting on the side of the bezel where it was struck. No optical or electrical malfunctions were detected.

I won't do "The Toilet Test" on this flashlight, because some leakage was detected when I performed "The Suction Test" on it. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of albino mouse 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.

There is knurling (diamond-shaped texturising) on the barrel and 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.

Measures 51,500mcd on a Meterman LM631 light meter.
Beam is a bit wider than usual for a reflectored LED; hence the lower-than-expected reading.

Test unit of this and one other flashlight were sent by J.W. of AdvancedMart, and were received late on the morning of 06-10-05.
