This is a good looking, nice feeling 2xCR123A cell Luxeon K2 LED flashlight in an almost all aluminum case. The only non-metal parts visible from the outside are the rubberised pushbutton on/off switch, and the optic of the Luxeon LED.

It features two light levels (high and low), and a blinking mode that is easily accessible regardless of which mode the flashlight is in (high, low, or off) when you wish to use it.

Speaking of the Luxeon K2 LED, it's using what I believe is a Fraen collimator. This optic produces a relatively tight beam with a mainly square configuration (a circular centeral hotspot with a square corona).

It is brighter than I expected it to be given its current consumption.


To use the flashlight, install the two included CR123A cells first (see the "Feeding Time" section directly below), and then you can go to town.

Press the rubbery button on the barrel gently until it clicks and then release it to turn it on high.

Press the and release the button again to turn it on low.

Finally, press and release the button the same way again to turn the flashlight off.

To access the blinking mode, press and hold the button down for three seconds, then release it. This mode is accessible regardless of what mode the flashlight is in at the moment.

There is no momentary or signalling mode available in this flashlight, so please don't look for or expect to find one.

The light can be turned off from any mode with a single press of the button after ~3 seconds - no need to cycle through low mode.

The flashlight comes with a nylon pouch/belt holster. The flashlight fits this holster bezel-up; a flap with a hook-and-loop fastener on it folds over the top and attaches to the body of the holster, so the flashlight doesn't just fall out. This holster fits belts up to 1.5" wide, and is 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, unscrew and remove the tailcap, gently place it on the ground, and kick it into the garden so the hungry, hungry praying mantids will think it's something yummy for their tummies and subsequently strike at it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the used CR123A cells out of the barrel, and dispose of or recycle them as you see fit.

Slide two new CR123A cells in the flashlight barrel, orienting them so the button-end (+) positive goes in first. Finally, screw the tailcap back on.
Aren't you glad you didn't kick that tailcap into the garden with all those hungry praying mantids now?

Here is what a praying mantis looks like.

Current usage measures 133mA (low) and 675mA (high) on my DMM's 4A scale.

Note the circular hole in the center.

I beat the living tweedle out of it (gave it ten firm whacks against the concrete floor of a patio; five whacks against the side of the tailpiece and five whacks against the side of the bezel), and found the expected damage. There is some VERY MINOR gouging to the bare Metaltsunomon - er - the bare Metalangewomon - um that's not it either...the bare a sec here...THE BARE METAL (guess I've been watching too much Digimon again! Now I'm just making {vulgar term for poopoo} up! ) on the side of the tailpiece and bezel where it was struck. No optical or electrical malfunctions were detected. It still works as well now as it did when I received it earlier this afternoon.

The flashlight appears to be weather- and water-resistant at the very least, despite there being a hole in the optic. 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!

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