Description: 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.
Dimensions: 56 x 11.5mm
