128xLED 3xD FLASHLIGHT

This flashlight has an amazing 128 5mm white LEDs in its head, and is powered by three D cells in its aluminum barrel.

The LEDs are protected by a transparent plastic window (or "lens" if you prefer that term, even though it does not modify the light in any manner).

I have not tested or seen a flashlight with this many LEDs until testing another 128 LED flashlight ~2 months ago.


 SIZE



Press the button on the barrel rather firmly until it clicks and then release it to turn the flashlight on.

Do the same thing again to turn the flashlight off.

There is no momentary or signalling mode available in this flashlight when it's off, however you can blink the flashlight while it is on by partially depressing the button. If you don't mind the backward or reverse feeling of this, you can blink the flashlight this way if necessary.



To change the batteries in this flashlight, unscrew and remove the tailcap, carry it outside, and throw it as hard as you can into the nearest open-pit zinc mine so the excavators will run over & flatten it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the open end of the barrel in your hand, so that the three used D cells fall into your hand or onto your feet (ouch!!!).
Dispose of or recycle them as you see fit.

Insert three new D cells into the barrel, orienting each D cell so its button-end (+) positive goes in first.

Screw the tailcap back on, and be done with it.
Aren't you glad you didn't huck that tailcap into the mine now?

Current usage measures 1,302mA (1.302A) on my DMM's 4A scale.
This equates to ~10.17mA per LED, so they are NOT AT ALL overdriven.

The flashlight appears to be reasonably sturdy. Ordinary flashlight accidents should not be enough to do it in. I administered the smack test on it (I beat the urine out of it {or "the living tweedle"out of it} - ten whacks against the concrete floor of a patio; five whacks against the side of the tailcap and five whacks against the side of the bezel), and found the expected damage There is some minor gouging to the bare Metalwargrowlmon - er - the bare Metalraidramon - um that's not it either...the bare Metalimperialdramon...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 tailcap and bezel where it was struck. No optical or electrical malfunctions were detected. I also scraped a spot on the barrel to the bare metal with the blade of a folding knife; this tells me that the finish is a Type II anodizing - not the HA-III found on some of the high-end flashlights.

Would I really try to cut up a brand spanken new flashlight I paid perfectly good money for?
You bet your sugar-coated toilet muscle (sweet patootie) I would, if it's in the name of science.

When I unscrewed the tailcap, relieved the barrel of its batteies, and then performed that dreadful suction test on it, minor air leakage was detected. There is an O-ring on the tailcap, but not on the bezel (head). So water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside through the outside of the bezel (head). So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of gila monster pee, glasses of milk, slush piles, mud puddles, tubs, root beer floats, toilet bowls, cisterns, sinks, cups of coffee, fishtanks, dog water dishes, old yucky wet mops, wall-mounted porcelain urinators, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in moderately bad weather.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, unscrew & remove the bezel (head) & remove the LED module, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater, got thrown into a glass of milk, fell in a root beer float, or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your flashlight to smell like seaweed, sour milk, or piss when you go to use it next. Besides, salt (from seawater or wee-wee), lactic acid (from cow lactation), or sugar (from root beer & ice cream) can't be very good for the insides.

There is knurling (cross-hatch-shaped texturising) over most of the barrel; this helps to aid in retention (the ability to hold onto the flashlight when your hands are oily, cold, or wet). This knurling isn't very aggressive, but it does help in aiding retention.

The beam is smooth - but with 128 LEDs, it better damn well be.

The LEDs all appear to be well-matched for brightness and tint.
Lack of waterproofness will knock some points off its final rating , but the even, consistent tint of the LEDs will add a few points back on!!!


There are no resistors visible on the PC board itself, but there could very well be one inside that white central column.

The flashlight can be stood on its tail to use as an electronic "candle", beaming its white goodness on the ceiling and allowing the reflected light to illuminate the entire room hands-free.

The overall light output is fairly high; the large emitting area & small detector size causes a false low reading.

I don't normally provide beam photographs on a wall with non-Luxeon
flashlights, but this flashlight is bright enough for this type of photograph.

TEST NOTES:
Test unit was purchased on Ebay on 12-30-06, and was received on 01-05-07.


UPDATE: 01-07-07
This flashlight seems to be a bit finicky in whether it operates or not. Smacking the bezel (head) in the palm of my hand usually restores operation - "usually" is the operative word here - it does not ***ALWAYS*** work.
