Unknown-Type Luxeon I Flashlight, retail $(unknown)
Manufactured by Unknown; possibly Nuwai
Last updated 02-17-08

This is an unknown-type metal LED flashlight that has a white Luxeon I LED near the bottom of a mirror-smooth reflector. The LED and reflector are protected by a plastic window (or "lens", if you are more comfortable with that term, even though it does not modify the light in any manner). This LED feeds from two CR123A lithium camera cells (or "batteries" if you are more comfortable with that term).

It comes in a thick aluminum body, protected by a black Type II anodized finish.


This flashlight is easy to use.

Just depress the button on the tailcap until it clicks and then release it to turn it on.
Repeat the same action to turn it off.

There is no momentary or signalling mode available when this flashlight is off, however you can blink the flashlight while it is on by depressing the tailcap button partially (before it clicks) and holding it that way for as long as you want the flashlight off. Releasing pressure turns the light back on.
If you don't mind the backward or reverse operation, you can blink the flashlight this way if desired.

The unit comes with a fairly sturdy-feeling belt holster. The light fits this holster bezel- (head)-up; a flap with a hook & loop fastener on it folds over the top and helps prevent loss of the flashlight. The holster has a flap with hook-and-loop fastener and a heavy-duty snap on it - it fits belts up to ~2.2" wide. This allows you to place the holster on your belt without taking your belt off first.
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 meant to be used.

To change the batteries, unscrew & remove the tailcap, gently place it on the ground, and viciously kick it into the swamp so the hungry, hungry crocodiles will think it's something yummy for their reptile tummies and subsequently strike at it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the batteries out of the barrel and into your hand, and dispose of or recycle them as you see fit.
Or recharge them, but only if you've been using RCR123A Li:ION rechargeable cells.

Slide two new CR123A cells into the barrel, orienting them so their button-ends (+) positives go in first.

Screw the tailcap back on.
Aren't you glad you didn't kick that tailcap into the swamp with all those hungry, hungry crocodiles now?

Current consumption measures 477mA (RCR123A rechargeables) and 505mA (CR123A disposables) on my DMM's 4A scale.
This was a bit unexpected; current usage on rechargeable cells is usually higher than it is on disposables.

This flashlight appears to be reasonably durable, and it is. When I performed that terrible smack test on it (ten whacks against the concrete floor of a patio: 5 smacks against the side of the bezel and 5 smacks against the side of the tailcap), only some rather minor damage was found. There is some extremely minor gouging to the bare Metalcalumon - er - the bare Metalrenamon - um that's not it either...the bare Metalvenommyotismon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! Now I'm just making {vulgar term for poop} up!!! ) on the sides of the tailcap and bezel where it was struck.

No optical or electrical malfunctions were detected.

The barrel has a wide band of knurling (crosshatch-shaped texturising) on the barrel, and some flat areas & short fins machined into the bezel & tailcap. These help aid in retention (the ability to hold onto the flashlight when your hands are cold, oily, or soaked with milk, diet vanilla Pepsi, champagne (flat or bubbly), coffee, strawberry Fanta, beer, gasoline, pee, or water).

Speaking of water, this flashlight appears to be water- and weather-resistant, and possibly even submersible to shallow depths at minimum too.

The flat areas machined into the bezel function rather effectively as an anti-roll device.

Product was obtained from an unknown source on an unknown date.
It was found on the morning of 02-15-08 while I was looking for another product requiring beam cross-sectional analysis.
I believe I received it within the last three years.

If you sent this flashlight, please pipe up so I can properly thank you for it.
