The Dorcy L.E.D. K2 Luxeon is a small, sturdy handheld flashlight that uses a Luxeon Star K2 LED driven at ~6 watts, positioned near the bottom of a mirror-smooth reflector. It comes in an almost-all metal body, and has a transparent polycarbonate plastic window (or "lens" if you prefer, even though it does not alter the light in any manner) to protect the LED & reflector from dirt, dust, splashes, etc.

It feeds from six AAA cells, which are included - so you need not run out and purchase them before the flashlight can be used.

This is advertised as Dorcy's "Brightest LED Ever!", and my measurements do indeed confirm that!

The Dorcy L.E.D. K2 Luxeon is quite easy to use...feed it the six included AAA cells first, and THEN you can go set fire to the side of a toliet seat factory (Bemis Industries just south of downtown Seattle WA. USA comes to mind here) a block or two away.

Press the button on the barrel and then release it to turn it on in "high" mode.

Repeat the same action to switch it to "low" mode.

Repeat the same action to turn it back off.



To change the batteries, unscrew & remove the tailcap. Walk over to the dustbin (garbage can), drop the tailcap in, take the bin liner (garbage bag) to the outside wheelie bin (wheeled garbage can), drop it in that one, and wait for garbage day so that the dustman (garbage man) dumps the wheelie bin into his dust lorry (garbage truck) and drives off...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Remove the black plastic battery carriage from the barrel. If necessary, remove the six used AAA cells from it, and dispose of or recycle them as you see fit.

Insert six new AAA cells into the carriage, orienting them so that their flat-ends (-) negatives face the springs for them in each chamber.

Slide the battery carriage back into the barrel, orienting it so that the small protruding rod on one end goes in first.

Finally, screw the tailcap back on.
Aren't you glad that you didn't drop that tailcap into the dustbin (garbage can) now?

Current usage measures 371mA (low) and 667mA (high) on my DMM's 4A scale.



The L.E.D. K2 Luxeon appears durable, and it is. I performed "The Smack Test" on it...after beating the living tweedle out of it (ten whacks against the concrete floor of a porch; five whacks against the side of the tailcap and five whacks against the side of the bezel), only some gouging to the bare Metalgeogreymon - er - the bare Metalkyuubimon - um that's not it either...the bare Metalbeelzemon...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 feces} up!!!) on the sides of the bezel and tailcap where impact occurred was found. No optical or electrical damage was detected.

The primary purpose of "The Smack Test" is not necessarily to see if the exterior of the flashlight would be damaged; it's more about the internal components which would be subject to a high shock load ("G force") every time the poor, innocent, defenseless flashlight strikes the concrete.

The L.E.D. K2 Luxeon is water-resistant, but it is not submersible. It should survive an accidental dunking into shallow water provided that you fish it out right away, but "The Suction Test" showed that it has a slow leak around the bezel (head) area; and a fairly significant leak around the pushbutton switch - so falls into deeper water will cause it to fairly rapidly flood.

The light produced by the L.E.D. K2 Luxeon appears pure white, with no purple, blue, yellow, pink, red, or "rotten giraffe urine green" tint to it at all.

That "rotten beluga whale urine green" tint does not actually exist.
Measures 3,210,000mcd (high) and 2,150,000mcd (low).

Both measurements made on a Meterman LM631 (now Amprobe LM631A) light meter.

TEST NOTES:
Test unit was purchased in a Target store in Federal Way WA. USA on 06-30-09.

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