Compare red and green lasers

[partylighter]

I used a multimeter to meassure the light of a red and green laser by pointing the laser to th wall from 20cm distance and holding the luxmeter sensor also 20cm from the wall to measure the reflection from the wall. The results:

200mW red:
135-140 lux


50mW green:
220-230 lux


Also for the eye the 50 mW greenie appeared brighter. Is the red one really 200 mW ?

 

[Lol]

Yeah green appears up to 3-4 times brighter than red lasers at the same power.... Also that's a neat thing to do. Never thought about using a multimeter to test it.
Oh and, welcome to the forum!
