These are small, pre-wired red diode laser modules. That is, they already include the optics assembly, and they're 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.
They come prepped with power wires, approximately 5.25" (~14.50cm) in length.

The laser module is ready to go as soon as you receive it.

Both of these modules have adjustable focus.

 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.

These modules have an adjustable focus ranging from very narrow spot to medium spot; just rotate the "business-end" of the laser module one way or the other. If you unscrew the end all the way until it comes off, be careful not to let the small spring shoot out unnoticed and later fall prey to the hungry, hungry vacuum cleaner.

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.

Current usage measures:

14.57mA (module #1)
17.11mA (module #2)

Both measurements were performed on my DMM's 400mA scale.
This is with a Vf of 4.49 volts (closed-circuit, not open-circuit), using an Aixiz laser diode module power supply unit specifically made for this application.

Because these are components designed to be installed in something, and not flashlights meant to be carried around, thrashed, trashed, and abused, I won't try to drown them in the toliet tank, bash them 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 them, run over them with a 450lb Celebrity motorised wheelchair, stomp on them, use a medium ball peen hammer in order to bash them open to check them for candiosity, fire them from the cannoņata, drop them 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 them to the Daystrom Institute for additional analysis, or perform other indecencies on them 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) are of these modules, 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.

The following power output measurements were made:

First module: 6.3147mW (lens off), 4.1478mW (lens on)
Second module: 7.5144mW (lens off), 4.9569mW (lens on)

Those graphics near the lower left (if you can see them anyway) are my "Viva Piņata" posters.

Test units were furnished for spectroscopy and power output measurements by J.S. and were received on 03-09-09.

The laser module was 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.
