Let's try that soon as I saw the address on the package, I *knew* it wasn't a flashlight...

This is a small, pre-wired red diode laser module. That is, it's ready to connect to any source of 3 volts DC that you happen to have handy; whether that's a pair of 1.5 volt AAA or AA cells, a 3 volt lithium CR2 or CR123A cell, or a "wall wart" type AC adapter that you know has a closed circuit output of 3 to no more than 4.5 volts DC and can deliver at least 25mA.

 Size of product w/hand to show scale SIZE

To use the laser module, just connect it to any source of 3 to 4.5 volts DC via the included wires. Red is (+) positive, white is (-) negative.
There is no on/off switch; if you wish to use one you will have to supply and connect it yourself.

Because this device runs from any source of 3 to 4.5 volts DC, this section will contain very little additional information.
Just connect it to your chosen power source so that the red wire goes to the (+) positive, and the black wire goes to the (-) negative.

If (forward current) measures 22.40mA on my DMM's 400mA scale.
This is with a Vf of 4.50 volts (closed-circuit, not open-circuit), using an Aixiz laser diode module power supply unit specifically made for this application.
Measures 23.60mA at a Vin=3.306 volts.

Because this is a component designed to be installed in something, and not a flashlight meant to be carried around, thrashed, trashed, and abused, I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a patio, let my mother's big dog's ghost or my sister's kitty cats spring a leak (uranate) on it, hose it down with a gun, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

This web page look a lot like this one and this one?
Thought you'd say so.
These products are extremely similar, so I was able to use their web pages as a template for this one.
All of the photographs, spectrographic analyses, and measurements (current and optical output) is of THIS module, but much of the rest of the text was left "as is"; only a few things were changed in it from those web pages vs. this web page.

Beam photograph on the test target at 18".
Photograph was deliberately left uncropped so that the beam shape can be seen.

The following power output measurements were made:

Vin=4.500 volts: 7.9618mW (1cm), 4.6718mW (2cm)
Vin=3.306 volts: 8.7796mW (1cm), 5.5742mW (2cm)
Vin=3.306 volts: 10.293mW (point blank; entire laser beam irradiating sensor)

Spectrographic plot
Spectrographic analysis of this module.

Spectrographic plot
Same as above; spectrometer's response narrowed
to a band between 650nm and 670nm.
As you can see, the peak wavelength is ~655.30nm,
and the spectral line halfwidth is ~1.60nm.

USB2000 spectrometer graciously donated by P.L.

ProMetric analysis

Images made using the ProMetric System by Radiant Imaging.

Test unit was furnished for spectroscopic & beam cross-sectional analyses plus power output measurements by J.B. in Belgium and was received on 07-23-09.

It is not known where this diode laser module was manufactured.
A product's country of origin really does matter to some people, which is why I wanted to publish it on this web page.

UPDATE: 08-05-09
The person who sent this laser module wanted the output power measured at various input voltages.
Here are the results:

3.153 VDC = 10.1520mW
3.349 VDC =  9.9828mW
3.505 VDC =  9.9642mW
3.714 VDC =  9.9640mW
3.930 VDC = 10.4058mW
4.100 VDC = 10.4152mW
4.300 VDC = 10.1144mW
4.500 VDC = 10.3494mW

Low current usage
Can be powered from a low voltage DC source
Good power output
