Green lasers question

[mtnman]

Does anyone know the difference between a green laser in 532nm and 650nm? Which one is brighter or has the longest range?
Thanks

Brightness is determined by wattage… most green lasers in the market have a pretty standard color wavelength are generally of the 5mw (Class IIIa) flavor.

Range is determined by a few factors... research beam divergence along with the above.

If you want a quality laser for use on something like a rifle… it’s going to cost some bucks.
