How powerful is a 100Mw 532nm laser?

[MisterClang]

I bought a couple of lasers: 100mW 532nm and a 100mW 405nm laser from Laserbtb, and I was wondering how many times brighter the 532nm would be than the purple, in the night sky or a dark room, with no fog.

Intensely brighter. 100mW 405nm has nothing on 100mW 532nm.

MUCH brighter about 4 times brighter as it is what our cones pick up most competed to violet. HOWEVER this does not mean that it is any less powerful.

If you fire up the green in a dark room it will lit up alot while the 405 wont even if its powerful your eyes will make it look weak but it isnt, in fact its more dangerous because some would think its not very bright but it is as dangerous if you would get in your accidenly.

With the same power in terms of milliwatts, a 532nm source of light will be 192 times brighter than a 405nm source of light, given the same power.
