Let's try that again...as soon as I opened the envelope, I *knew* it wasn't a flashlight...

This is a small, pre-wired red diode laser module. That is, it already includes the optics assembly, and it's ready to connect to any source of 1.5 to 2.0 volts DC that you happen to have handy; whether that's a 1.5 volt AAA or AA cell, or a "wall wart" type AC adapter that you know has an output of at maximum 2 volts DC and can deliver at least 30mA.
It comes prepped with power wires, approximately 6.00" (~15.20cm) in length.

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


SIZE



To use the laser module, just connect it to any source of 2.0 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 1.5 to 2.0 volts DC, this section will contain very little additional information.

Current consumption measures 22.9mA at a Vf of 1.066 volts



Because this is a component designed to be installed in something, and not a flashlight, I will not beat it against the corner of a concrete stair or a steel rod, stomp on it, try to drown it in a toilet, run over it, or bestow upon it other misfortunes that may be bestowed upon flashlights, so this section of its web page will be relatively bare.

Wavelength appears to be approximately 650nm, in the red region of the spectrum.

Power output measures 1.9912mW on a laser power meter specifically designed for this purpose.

Beam is a lot smaller and not white as shown in this photograph.
The beam is clean, with no blobs, speckling, or other little evil things surrounding it.

Power output measures 1.9912mW on a laser power meter.
This makes it a CDRH Class IIIa laser product.

TEST NOTES:
Test unit was sent by a website fan and was received on 01-14-06.
This person did not furnish an email address, so if this was you, please pipe up so I can thank you for it.


UPDATE: 01-28-06
This laser has really great collimation. I noted this last night when I observed the beam spot on a wall at ~15 feet; the laser spot was still *VERY* small.

In light of this discovery, I've decided to increase its rating by 1/2 star.


PROS:
Clean beam with no artifacts
Maintains excellent collimation - more so than other modules I've handled
Durable construction - shock- and vibration-resistant
Operates on low voltage DC, such as from batteries


CONS:
Not labelled for CDRH classification - however, this module was intended to be installed in something; not a serious issue
Not water-resistant - however no laser module really is. Will not affect rating
