A very powerful 5mW green laser. Fun, but don't point in anyone's eyes.
These units include a momentary power button and two solder points for permanent on. The trim-pot adjusts the output power. We were able to push the current up to about 400mA where things started getting toasty, and very bright.
If you are in Australia: New regulations enforced by Australian Customs prohibit you from importing lasers rated greater than 1mW. Please do not order this item. You will have to pay extra money, and still won't get the laser.
Dimensions: 56 x 11.5mm
