This is a nifty little torch (flashlight) that I found on Ebay not long ago. I bought it because the price was right, it has two colors of LEDs in it, and it has a red laser module in it. All three functions are easily accessible with a single pushbutton.

It comes in an aluminum body, it has 11 white LEDs, 7 NUV (near-ultraviolet) 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 torch, feed it first (see directly below), and then you can go paint the town red. Or white. Or near-ultraviolet.

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 white LEDs off and NUV LEDs on.
Press the button on the barrel until it clicks and then release it to turn the NUV LEDs off and the diode laser on.
Press the button on the barrel until it clicks and then release it to turn the torch 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, throw it to the ground, and stomp on it with old or used bowling shoes...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 spring on one end of the carriage goes in first. Finally, screw the tailcap firmly back on.
Aren't you glad you didn't stomp on that tailcap now?

Current usage measures 136.6mA (white LEDs) 142.2mA (NUV LEDs) and 32.2mA (laser diode) on my DMM's 400mA scale.
This equates to ~12.42mA per LED (white) and ~20.31mA per LED (NUV).

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 around the switch and more so through the bezel. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of dingo 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, 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 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 plain white box it came in.
The laser in this torch measures 6.51mW, making it a CDRH Class IIIb instrument.

Wavelength of the NUV LEDs appears to be ~402nm, and the laser diode ~650nm.

Wavelength is too short for me to obtain an intensity reading.
Color is not magenta like you see in this photograph;
it should appear a deep royal purple to the naked eye.

TEST NOTES:
Test sample was purchased on Ebay and was received on 02-18-06.

As far as I can determine, product was made in Hong Kong. A product's country of origin really does matter to some people, which is why I published it on this web page.

Because this product outputs more than 5mW of laser radiation, I need to call it a "module" instead of a "pointer".

UPDATE: 02-23-06
Divergence of the laser beam appears to be a bit higher than expected for a red laser module. It's not terrible and awful by any means, but it *IS* a bit higher.

UPDATE: 02-26-06
Brightness of the white LEDs appears to be higher than expected for such an inexpensive instrument. Yes, this is a good thing.
