This is a directly-injected red diode laser module that is advertised to have an output adjustable from 0mW to 40mW via a setscrew mounted on its own cable.

The product consists of three components: the laser module itself, the setscrew for adjusting power, and a power supply that plugs into any two- or three-slot 90 to 240 volts AC 50Hz or 60Hz power receptacle. All of the components are prewired, so all you need to do is plug it in.

SIZE

To use this laser, just plug the "wall wart"-type power supply into any two- or three-slot 90 to 240 volts AC 50Hz or 60Hz power receptacle, and the laser will come on.

To adjust the power output, take a small standard screwdriver and turn the gold colored screw on the small blue trimmer pot

. Turn it clockwise to reduce laser power, and counterclockwise to increase laser power.
See the photograph directly below to see what this trimmer looks like.

It is attached to the laser diode module by a pair of wires ~4 1/2" (13cm) in length.

When you're finished using this laser, unplug the power supply from the wall.

Because this product is designed to be line-powered, this section can and will be skipped.

This is a laser, not a flashlight. So I won't whack it against a steel rod or against the concrete floor of an outdoor patio, run over it with a 450lb electric wheelchair, try to drown it in the toilet bowl or the cistern, throw it, let my housemate's kitties go #1 on it, stomp on it, or subject it to other abuses that a flashlight might have to endure.

The collimating lens is adjustable, so you can adjust the beam focus to give you a tight beam close up, or far away. You adjust the focus by turning the black plastic ring at the front of the laser module clockwise or counterclockwise.

The laser's power output is also adjustable, from a couple of hundred microwatts (µW) to just over 40 milliwatts (mW).

This laser is not water-resistant, so please be extra careful when using it around sinks, tubs, toilets, fishtanks, pet water bowls, or other places where water or water-like liquids might be found. And you'll probably want to cover it up or otherwise get rid of it (such as by putting it in a pocket or bag) if you need to carry it somewhere or other in rainy or snowy weather.

TEST NOTES:
Test unit was purchased on Ebay on 07-31-06, and was received at 2:29pm PDT on 08-08-06.

UPDATE: 09-07-06
I have decided to rate this product 4½ stars and place it in The Trophy Case on this website.

PROS:
Beam is "clean", with no visible speckling or artifacts around it
Fantastic variable power levels available
Wide adjustment range from <0.2mW to >40mW
Focus is somewhat adjustable

CONS:
Not water-resistant - but most other lasers aren't either. Will not figure into my rating
CDRH warning label is not on the laser
Power adjustment control is a bit on the small side
