8xLED Laser Flashlight, retail 52
Manufactured by (Unknown)
Last updated 01-27-10

This is a nifty little flashlight that I found on Ebay not long ago. I bought it because the price was right, and it has both white LEDs and a red laser module in it. Both functions are easily accessible with a single pushbutton.

It comes in a handsome 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.

The part number shown on the box is: COTHFLLTLP03-4983


To use this neat multipurpose flashlight, feed it first (see directly below), and then you can go paint the town red. Or white.

Press the button on the barrel until it clicks and then release it to turn the white LEDs on.
Press the button on the barrel until it clicks and then release it to turn the flashlight all the way off.
Press the button on the barrel until it clicks and then release it to turn the diode laser on.
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 shampee) 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 black 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.

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 plastic 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 173.1mA (LEDs), and 34.8mA (laser diode) on my DMM's 400mA scale.
This equates to 21.6375mA per LED.

Because this product contains a laser, the thrash test will not be performed. I never perform this particular test on lasers or products which lase.

Although there is an O-ring on the tailcap where it fastens to the barrel, it failed "The Suction Test" rather miserably; so water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside through the bezel and more so around the switch. 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 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 lightly to at most 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, got nocked into a cup of yogurt, 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 pee-pee), lactic acid (from milk or yogurt), or sugar (from root beer and vanilla ice cream) can't be very good for the insides.

This product is not labelled for CDRH compliance (which they must if a laser is included). Not on the flashlight itself, and not on the white box it came in.
The laser in this flashlight measures 5.18mW, making it a CDRH Class IIIb instrument.

Unit was purchased for just 52 on Ebay on 05-30-07, and was received on the early-afternoon of 06-01-07.

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