Last updated 08-18-09





The Lumapower D-Mini Digital SE Flashlight (hereinafter, probably just called a "flashlight") is a small but sturdy aluminum LED flashlight.

It comes in an almost all-aluminum body (protected with a Type III HA finish), has a Cree XR-E (Q5) LED at the bottom of either a mirror-smooth or lightly texturised reflector (both are included), has three intensity settings, and powers that LED with a single CR123A lithium camera cell.

The LED & reflector are protected by a glass window (or "lens" if you prefer, even though it does not modify the light in any manner), not a plastic one.

And this flashlight not only has a GITD (Glow In The Dark) O-ring between the lens ring and the bezel, it also has a GITD tailcap switch button.


 SIZE



Feed this flashlight a single CR123A cell first (see directly below), and THEN you can go set the town on fire.

Press the tailcap button until it clicks and then release it to turn the flashlight on high.
Press & release it the same way to turn it off.

Press & release it the same way to turn it the flashlight on medium.
Press & release it the same way to turn it off.

Press & release it the same way to turn it the flashlight on low.
Press & release it the same way to turn it off.

Just like it reads on the back of many shampoo bottles, "lather, rinse, repeat".
In other words, pressing & releasing the button again at this point turns the flashlight on in high mode.



The reflector can be swapped out with the one included with the package.
To do this, simply follow these four simple instructions:
  1. Unscrew & remove the lens ring, and set it aside.
  2. Tip the reflector out of the flashlight and into your hands, and place it somewhere safe.
  3. Place the other reflector in the bezel (head), narrow-end first.
  4. Screw the lens retaining ring firmly back onto the flashlight.
The unit came with a third reflector (part of my prize package), but it is significantly too large to fit, so it cannot be tested.

The product comes with a sturdy nylon belt holster that holds the flashlight *AND* two spare CR123A cells.
The flashlight fits this holster bezel-up; a flap with hook & loop fasteners (similar to - if not Velcro) secures the flashlight in place; another similar flap secures the batteries in place.
This holster fits belts up to 2.0" (5.08cm) wide; however since I do not own or use pants that require a belt, I am unable to test this accessory in the manner in which it was intended to be used.



To change the battery in this fashlight, unscrew and remove the tailcap, and set it aside.

Dump out the dead CR123A cell, and dispose of or recycle it as you see fit.

Insert a new CR123A cell in the flashlight's barrel, orienting it so its button-end (+) positive goes in first.

Screw the tailcap firmly back on.
There, done with that.



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 patio: 5 smacks against the side of the bezel and 5 smacks against the side of the tailcap), only very, very, very minor damage was found. There is some extremely minor gouging to the bare Metaldemidevimon - 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. Actually, I don't even think the gouging exposes the bare metal; it appears to be denting rather than gouging.

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.


Here's proof that I really performed "The Toliet Test" on it.
After being submerged in ~12" of water in the cistern (toilet tank) at 68F (20C) for one minute and then being dried off with some bungwipe, no water was detected inside.

The light emitted by this flashlight is pure white, with no red, pink, yellow, blue, purple, or "rotten elephant urine green" tint to at all.

Measures 177,700mcd (low), 718,000mcd (medium), and 2,720,000mcd (high) with the STIPPLED reflector.
Measures 279,000mcd (low), 1,890,000mcd (medium), and 3,830,000mcd (high) with the SMOOTH reflector.

All measurements were taken on a Meterman LM631 light meter.

TEST NOTES:
Test unit was won on a giveaway on CPF Marketplace on 02-13-08, and was received on the afternoon of 03-28-08.

The unit came with a third reflector (part of my prize package), but it is significantly too large to fit, so it cannot be tested.

The only other item I've won from any internet forum was the PK-Autographed Flashlight Bag that I won during a raffle on Candlepower Forums on 09-07-04.

I believe this product was made in Hong Kong, but I have no direct evidence with which to verify this.
A product's country of origin really does matter to some people, which is why I published it on this web page.


UPDATE: 03-29-08
I may go dumpster-diving for the box after sunrise this morning, as there is a slight but not insignificant chance that something may have been left behind inside the shipping container (a well-taped up shoebox). This is the recycling dumpster, not the garbage dumpster; so I will not have to deal with hypodermic syringes, cat poop, used Massengill brand post-menstrual disposable douches, urine-soaked teddy bears, crumpled damp paper towels (not knowing what they're damp *WITH*), dirty diapers, smelly wilted cabbage, dead rats, used sanitary napkins, or other yucky things.
Another update pending, with my findings (if any).


UPDATE: 03-29-08
No, you aren't seeing things.
Yes, a same-day update.
Much as I suspected that it was when I tossed it, the shipping box was absolutely, positively, 100% empty.
The dipsty dumpster was empty enough that I was able to locate the box immediately and stab it with my cane to bring it to the edge of the dumpster, so I did not have to actually crawl *IN* the dumpster.
To put it briefly, there is no barrel extender or larger bezel assembly in there; therefore, the larger reflector included with my prize package still cannot be used.
