Qiaoba Green Laser Module Diode Laser Light 532nm (Green Dot) 5mw (1)

I was surprised at how bright it is when driven with 3 VDC. The beam seems well collimated with not much divergence. It is easily bright enough to be seen at night when pointing out stars and constellations, even in a low humidity sky. The manufacturing looks good. The laser itself is mounted into a brass barrel offering good heat sinking. The only partial negative is that the circuit board is exposed and held in place with hot glue. As long as you protect the circuit board, this laser should last a long time. the two power leads are useful, since no soldering to the circuit board is needed.

I got these to replace a laser diode that burnt out in a laser pointer I made. These diodes worked fine as a replacement. I don't have any complaints about them. I would buy more in the future if I need more.

Goes well with my UV, red, and blue lasers. Works great, no issues.

Nice and bright laser before it heats up. Gets hot and then becomes dim and turns off. If you let it cool down, it will work great for a min before repeating.

Quality piece that produce strong light and was easy to work with.

Very nice laser. Very bright. Easy to hook up. You pay for 1 laser you get 1. Will buy more.

Although the laser has a lens focus adjustment, the beam DOT can not adjust below 0.25 Inch at 5 feet. very bright however

This has a nice sharp beam. Well defined and very bright. A good body for a pointer.
