The Batonlite is a tough, metal "N" cell flashlight that uses 3 white LEDs and a diffusing lens to produce an uncommonly bright and diffuse beam. In the proper hands, it is also functional as an Asian weapon known as a Kubotan™ .
The Batonlite is also individually serialized (mine is #001487) like any decent instrument should be.


Rip open the pack and start using it right away, as it comes with batteries pre-installed.
There are two ways to get light from a Batonlite: Press the button on the end of the tailpiece to flash the light when needed, or twist the entire tailpiece about 1/4 turn clockwise (as the light is facing forward) to have it stay on by itself.
To turn it off, either release the button or twist the tailpiece 1/4 turn counterclockwise.

Since I have no training in the martial arts, I will not in any way discuss the use of the Batonlite as a Kubotan. This is something to be left in the hands of trained personnel only. Everyone else, enjoy the Batonlite's utility as a bright, super tough flashlight and leave it at that, shall we?

The Batonlite comes with an oversized, anodized keyring attachment that fits on a freely swivelling collar on the butt of the flashlight. I ended up using this ring to repair a broken part on my wheelchair, so it is not pictured here. :(

To change the batteries in your Batonlite, remove the tailcap and dump out the deaddies, and insert three new "N" cells button-end first. Screw the tailcap back on until the light comes on, back it off 1/4 turn, and be done with it.

The packaging indicates a useful battery life of 12 hours continuously; longer life can be achieved by not letting the thing burn clean to the ground; using it on an intermittent basis only like one would use any other flashlight.

The Batonlite is one of the tougher LED flashlights out there. It is made almost entirely from anodized aircraft aluminum and is, for all intents and purposes, indestructible. The diffusing lens is made from G.E. Lexan, the strongest clear plastic available today. And the light is sealed with "O" rings to give it at least some resistance to water. A suction test just conducted on the component most vulnerable to leakage (the momentary pushbutton switch) showed NO air leakage whatsoever, so this light should be completely waterproof. A dunk test scheduled for a little later will confirm this.

The light is physically robust and durable. Attempts to flatten it under the wheels of a 400 pound motorized wheelchair failed, and the flashlight came out of five crushing back and forth rollovers with a solid tire (not the pneumatic kind) with only a very minor surface scuff, and I had to put on my +4 diopter readers to find that.
The carpeting seen in the above picture is approximately 0.08" thick from base to top of pile, and there is no backing or padding of any kind whatsoever. The only real protection it provided was to the linoleum flooring underneath - the flashlight would have gouged it otherwise.

The Batonlite uses three superbright Nichia white LEDs behind a diffusing lens, so the beam is not only bright, but is lacking those blue spots and rings so common with other wider-angle white LED flashlights.

The tailpiece seems to wobble slightly when the light is used in intermittent (pushbutton) mode. I did not at all expect this out of such a finely made instrument. I don't believe this affects its performance in any way though, but it was noticeable.

To adjust the sensitivity of the pushbutton, screw the tailpiece on more or less until it suits your needs. Tightening it until just before the light comes on will make the button fairly sensitive, and backing it off more makes the button less sensitive.
If you back it off 1 full turn from the point the light turns itself off, the chances of it going off in storage or inside your backpack are very close to zero. Taping it in this position before stowage will ensure you have a fresh light when you reach your campsite. Of course, so will dumping the batteries and storing it empty.

This is the Batonlight's soft, even beam on the test target.
