Nuwai TM-116x 5W Luxeon Flashlight, retail $69.95 (
Manufactured by Nuwai (
Last updated 02-14-07

The TM-116x flashlight comes in an almost-all-aluminum body, and features a 5 watt Luxeon Star LED in its business-end to produce its light, and has two CR123A cells in the barrel to power that LED. The beam width is adjustable by turning the bezel (head) clockwise or counterclockwise.

The only parts of the flashlight that are visible that aren't metal are the window on the business-end, and the rubberised pushbutton on the end of the tailcap.


To use this flashlight, feed it the two included CR123A cells (see below), and then you'll be ready to go to town.

Press the rubberised button on the tailcap until it clicks and then release it to get light. Do the same thing again to not get light.

There is no momentary or signalling mode available when the flashlight is off; however you can blink it while it's on by pressing the tailcap button more gently than you would for turning it off; press it and hold it BEFORE it clicks. If you don't mind the backward or reverse feeling of this, you can blink the Nuwai this way if desired.

This flashlight has an adjustable beam width. Turn the bezel counterclockwise (as if unscrewing it) to widen the beam; turn the bezel clockwise (as if tightening it) to narrow the beam.
If you unscrew and remove the bezel completely, this exposes the 5 watt LS LED, allowing you to use the flashlight in "candle mode". The flashlight will not stand on its tailcap though, so you'll want to put it in a roll of bungwipe if you wish to use the flashlight in this mode and then set it upright somewhere.

The Nuwai comes with a nylon belt holster. The flashlight fits it bezel (head) up, and can be affixed to a belt up to 1 1/2" wide.

Since I do not use or own pants that require a belt, I cannot test this accessory in the manner in which it was intended.

To change the batteries in the Nuwai, unscrew and remove the tailcap, throw it in the crapper, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead. ;-)

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

Insert two new CR123A cells in the barrel, button-end (+) positive first, then screw the tailcap back on.
Aren't you glad you didn't flush away that tailcap now? ;-)

Current usage measures 1,010mA with disposable CR123A cells, and 1,284mA on rechargeable R123A cells.
Both measurements were taken on my DMM's 4A scale.

This flashlight appears at least *reasonably* durable, and it did well with the smack test. Ten whacks (five against the tailcap, five against the side of the bezel) against the corner of a concrete stair and no electrical or optical malfunctions were detected. Physical damage was very, very, very minor - small dings on the side of the tailcap and bezel that are hardly more than surface scuffs.

With some difficulty, I scratched through the exterior finish of this flashlight with the blade of a Swiss army knife, showing the flashlight has a Type II anodizing.
Would I really try to cut up a perfectly good, brand spanken new flashlight?
You bet your sweet patootie I would, if it's in the name of science.

Water-resistance is a little more different. Although it is sprinkle- and splash-resistant, it is not waterproof or submersible. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of wharf rat 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, remove the bezel (head), dump out the water 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 wee-wee when you go to use it next. Besides, salt (from seawater or urination) can't be very good for the insides - the electrical contacts, the LED, and the reflector.

The Nuwai has square, raised areas along much of the length of the center of the barrel, and some widely-spaced longitudinal ridges on the tailcap and bezel, so retention (the ability to hold the flashlight when your hands are cold, wet, or oily) should not be much of an issue.

The Nuwai comes with a wrist lanyard, already affixed to a small hole in the tailcap. The lanyard is large enough to go around any wrist, and easily goes around the flashlight itself, so you can hang the flashlight from a tree branch, horizontal pole, water pipe, or other tubular or pipe-like object you happen to spot handy that has no readily accessible "end".

The flashlight fits in the holster rather snugly, especially the bezel.

This photograph shows how the flashlight should be fitted into the holster so that the hook-and-loop closure on the flap works.

That red star thing on the ceiling is a worries there.
