Last updated 03-09-07





The 8W LED "Police" flashlight (hereinafter, just called a "flashlight" because it has no formal name that I'm aware of) comes in an almost all-aluminum body, covered with a Type II anodizing for protection, has a rubbery two-level pushbutton on the tailcap, and is powered by either two CR123A primary (disposable) or two RCR123A secondary (rechargeable) cells.

It has what I believe is a Luxeon III LED at the bottom of a smooth reflector; these are protected by a glass window (or "lens" if you prefer, even though it does not focus or otherwise modify the beam).


 SIZE



To use the flashlight, install the included batteries first (see the "Feeding Time" section directly below), and then you can go to town.

Press the rubbery button on the tailcap firmly until it clicks and then release it to turn it on in high mode.

Press and release the button the same way again to turn the flashlight back off.

Press and release the button the same way again to turn the flashlight on in low mode.

Press and release the button the same way again to turn the flashlight back off.

Just like it reads on the back of many shampoopoo (or shampeepee) bottles, lather, rinse, and repeat. In other words, pressing and releasing the button the same way again turns it on in high mode.

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.

The flashlight comes with a holster. The flashlight fits this holster bezel-up; a flap with Velcro on it folds over the top and attaches to the body of the holster , and a snap on a strip that crosses over the front fits into another snap, so the flashlight doesn't just fall out. This holster fits belts up to 2.5" wide, and can either be threaded through the belt or attached to the belt after your pants are already on, thanks to a snap that can be unfastened to attach the holster to your belt, and then snapped back together once you have the holster fitted in place. I do not own or use pants that require a belt however, so I cannot test this accessory in the manner in which it was intended to be used.



To change the batteries when necessary, unscrew and remove the tailcap, throw it in the garbage can, and empty the garbage can outside where the garbage man will see it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the two used CR123A cells into your hand, and dispose of or recycle them as you see fit. If they're rechargeable RCR123A cells, pop them in the charger instead of getting rid of them.

Insert two new CR123A or freshly charged RCR123A cells in the barrel, button-end (+) positive first. Screw the tailcap back on, and be done with it. Aren't you glad you didn't throw away that tailcap now?

Current measures 1,130mA (1.130 amps).
The secondary (rechargeable) RCR123A Li:ION cells that were furnished with this flashlight were used for this measurement. I cannot measure current on low because modes are controlled with the flashlight's tailcap switch.

Current measures 531mA on primary (disposable) CR123A cells.

This flashlight appears at least fairly durable, but it is NOT!!! 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), the expected damage was found. There is some minor gouging to the bare Metalgreymon - er - the bare Metalgarurumon - um that's not it either...the bare Metalseadramon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! ) on the sides of the tailcap and bezel where it was struck. More importantly, the flashlight quit working.

The problem has been isolated to the tailcap; the flashlight lights up when the metal barrel & battery (-) terminal are bridged with a metal screwdriver.

When I smacked the flashlight on the opposite side of the tailcap three times against concrete, the flashlight began to function properly again. So I guess I didn't flush $61.55 down the {vulgar term for feces}bowl after all.

There is a black Type II anodized finish over all of the exposed aluminum; this should help keep the flashlight looking newer for longer, even if it goes up against coins, keys, or other flashlights.

There are four O-rings on the barrel at the tailcap, at the bezel, and at the lens ring, and the flashlight has the word "SUBMERSIBLE" silkscreened on the side of the bezel, but the flashlight failed "The Suction Test". So water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside.Please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of Norway rat 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, 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 urination), lactic acid (from moo juice), or sugar (from root beer & ice cream) can't be very good for the insides.

O WAIT!!!
When I disassembled and then reassembled the flashlight and then performed that dreadful suction test on it again, NO AIR LEAKAGE WAS DETECTED!!!
So it might very likely be submersible after all!!!

The flashlight does not stay on long enough to obtain an accurate temperature measurement, but after ~5 minutes on high, the exterior of the flashlight measures 109F (42.8C), and the LED itself measures 144F (62.2C). Ambient temperature in the testing area was 78F (25.5C).

Measures 1,830,000mcd (low) and 3,790,000mcd (high).

These measurements were taken with the RCR123A
rechargeable cells furnished with the flashlight.

Measures 917,000mcd (low) and 1,740,000mcd (high).

These measurements were taken with CR123A disposable cells.
All measurements were taken on a Meterman LM631 light meter.
