Thanks for the fast response!
In your experience, can our eyes tell the difference between a 300mW and 500mW blue laser of this kind(step motor laser for parties, not in laser pointers)?
I know this is an old post. but just wonder usually how can you tell if a blue laser is 500mW? From the video, anyone knows if this party laser is really 500mW or below?
