The 1W Focusable LED Flashlight is a super bright, small handheld LED flashlight in a metal body. It has a bright 1 watt white LED behind a positive (magnifying) lens - the bezel (head) can be moved in and out to allow for focusing the flashlight's beam as you see fit.

It feeds from 3 AAA cells held in a side-by-side carriage in the flashlight's barrel, and is turned on & off with a rubberised pushbutton on the end of the tailcap.


Use this flashlight much you'd use many others: press the rubberised button on the tailcap firmly until it clicks and then release it to turn it on.
Do the same thing to turn this flashlight back off.

Now comes the interesting part.
The beam width is adjustable simply by grasping the barrel with one hand, and the bezel (head) with the other.
Pull them apart to cause the beam width to narrow; and push them together to widen the beam.

This flashlight comes with a nylon belt holster; the flashlight fits this holster bezel-up (head-up); a flap with hook-and-loop fastener folds over the top to help prevent loss of the flashlight while you're running or when you get yourself in a pickle (jammed in a narrow doorway, for instance).
This holster is designed to fit belts up to ~1.8" wide; however since I don't own or use pants that require a belt, I cannot test this accessory in the manner in which it was intended to be used.

To change the batteries in your Micro 1W Focusable LED Flashlight, unscrew and remove the tailcap, dash it to the ground, and stomp on it with spiked golf shoes...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the black plastic battery carriage out of the barrel and into your hand. If necessary, remove and dispose of or recycle the used cells if they are present in this carriage.

Insert three new AAA cells into the carriage, one in each compartment. Orient each cell so the flat-end (-) negative faces a spring for it in its compartment.

Once the carriage is full, insert it into the flashlight's barrel, aiming it so the more "pointy" metal contact on one end goes in first. Screw the tailcap back on, and be done with it.
Aren't you glad you didn't stomp on that tailcap now?

Current usage measures 811mA on my DMM's 4A scale.

This flashlight appears at least fairly durable, and it is!!! When I performed that terrible smack test on it (ten whacks against the concrete floor of a front porch: 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 minor gouging to the bare Metaldarktyrannomon - er - the bare Metalarukenimon - um that's not it either...the bare Metalmalomyotismon...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 & bezel where it was struck.
No optical or electrical malfunctions were detected.

It is also waterproof and even submersible to shallow depths at minimum - it passed "The Suction Test" both on the back of the barrel and on the tailcap even when clicking the switch button several times while continuing to suction it.

The light's beam is focusable from a fairly narrow spot to a wide spot; very little corona or spill beam is present despite the beam's level of focus.

The only thing that pisses me off (if only just a little) about this flashlight is that the beam focus assembly moves perhaps a bit ***TOO*** easily. Your desired beam width will become lost by the simple act of placing this flashlight in its included holster.

The very narrow beam accounts in large part for this high value.

Beam photograph (wide beam) on the test target at 12".
Measures 412,000mcd on a Meterman LM631 light meter.
I intentionally left this photograph uncropped to allow you to see the entire beam.

That darker spot at the left-center in the second analysis

Test unit was sent by my contact at LEDTronics on 06-14-08 and was received on the afternoon of 06-16-08. I was not able to find this product on this website, so I simply reevaluated it as if I had just received it.

Product was made in the United States.
A product's country of origin really does matter to some people, which is why I published it on this web page.

UPDATE: 01-29-12
This product was used during a recent extended (over 90 hours!) electrical power failure.

Very bright
Reasonably durable
Waterproof and even submersible to shallow depths
Easily adjustable beam width adjustment

Beam adjustment is possibly ***TOO*** easy
