Digital Energy 8xLED Flashlight w/ Laser, retail $4.99 (www.radioshack.com...)

This is the TP™ (True Power) Digital Energy 8xLED Flashlight w/ Laser (hereinafter,. probably simply called a, "flashlight"); it is a nifty little flashlight / laser pointer combo that I purchased at a nearby Radio Shack while I was in the neighbourhood to purchase some Fancy Feast 'Mornings' canned cat food on the morning of 09-07-12 to try on our five furry fuzzbombs.

It has both white LEDs and a red laser pointer in it.
Both functions are easily accessible with a single pushbutton.

It comes in a handsome jet black aluminum body, it has 8 white LEDs and a red diode laser in its business-end, and feeds from three AAA cells that are held in a side-by-side carriage in the barrel.

SIZE

To use this neat multipurpose flashlight, remove it from the packaging using a pair of dikes (the wirecutters, not the other kind!

) to snip the thick nylon band that holds it in place, feed it a trio of AAA cells next (see directly below), and then you can go paint the town red. Or white.

1: Press the button on the barrel until it clicks and then release it to turn the white LEDs on.

2: Press the button on the barrel until it clicks and then release it to turn the flashlight all the way off.

3: Press the button on the barrel until it clicks and then release it to turn the diode laser on.

4: Press the button on the barrel until it clicks and then release it to turn the flashlight all the way off.

Just like it reads on the back of many shampoo (or shampotty) bottles, "lather, rinse, repeat". In other words, the cycle starts over with the next press of the button.

To change the batteries, unscrew and remove the tailcap,gently place it on the ground, and kick it in the garden so the praying mantids will think it's something yummy to eat and subsequently strike at it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the white plastic battery carriage out of the barrel and into your hand. If necessary, remove and dispose of or recycle the used AAA cells from it. Do not attempt to dispose of them by flushing, and for God sakes please do not throw them into a trout-filled stream!!!

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

Slide the now-full battery carriage into the flashlight barrel, orienting it so the (+) sign embossed into the metal on on one end of the carriage goes in first.

Finally, screw the tailcap back on.
Aren't you glad you didn't kick that tailcap into the garden with all those hungry, hungry praying mantids now?

Here is what a praying mantis looks like.
I found this guy on the morning of 09-08-06 clinging to the basket of my scooter.

Current usage measures 224.00mA (LEDs) and 23.70mA (laser) on my DMM's 400mA scale.
This equates to 28.00mA per LED.

Because this product contains a laser, "The Thrash Test" will not be performed. I almost never perform this particular test on lasers or products which lase.

(You may be asking: What in the name of Davy Jones' locker is "The Thrash Test" anyway?!?
It is functionally identical to "The Smack Test"; it just has a more dramatic sounding name

)

I did however perform, "The Nife Test" on it, and I was fairly easily able to scratch through to bare Metalmegatogemon - er - the bare Blackmetaltrailmon - um that's not it either...the bare Metalpaildramon...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!!!) where I scratched it on the tailcap. This tells me that it probably has a baked enamel finish (though possibly Type II anodizing) rather than the much harder HA-III (hard anodized type III) finish that is found on some of the other mid- and high-end flashlights.

Although there is an O-ring on the tailcap where it fastens to the barrel, it failed "The Suction Test" VERY slightly; so "The Toliet Test" is also a no-no in this instance. Water, milk, diet Pepsi, coffee, uranation, root beer, or other liquids could get inside through the bezel and probably around the switch as well. So 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 uranators, or other places where water or water-like liquids might be found. Some 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 shallow water, you'll probably be OK if you fish it out ***RIGHT AWAY***, but if it falls into deeper 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, got nocked into a cup of yogurt, if somebody squirted a Massengill brand post-menstrual disposable douche or a Fleet brand "ready-to-use" disposable enema at it (and hit it with the douche or the enema), if it fell into a root beer float, if somebody dumped vinegar all over it, or if somebody or something got "pyst off" at it and subsequently "pist"

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, flowers, fresh butts, salad dressing, or uranation when you go to use it next. Besides, salt (from seawater, douches, enemas, or pee-pee), lactic acid (from milk or yogurt), acetic acid (from vinegar), or sugar (from root beer and vanilla ice cream) can't be very good for the insides.

Those artifacts (the blotches you see on the target) are caused by the camera, and do not exist in reality.
Beam image bloomed ***SIGNFICANTLY***; the white color does not exist either.

TEST NOTES:
Test unit was purchased at a Rat Shack store in Federal Way WA. USA on the morning of 09-07-12.

UPDATE: 00-00-00

PROS:
Nifty 2 in 1 product
Uses LEDs instead of a hot, breakage-prone incandescent lamp
Uses batteries that are common and relatively inexpen$ive
Water-resistant and even submersible to shallow depths for short periods
Unit is properly labelled for both laser wavelength & power output.

CONS:
Finish appears to be baked enamel -- or possibly type II anodizing
LEDs are a bit overdriven, though not horribly so
Uses a battery carriage -- one more thing to break or lose
