Hi all, I am deciding on getting the brightest green laser possible. I currently have a 5w 445nm blue laser but wondering which laser will be the brightest possible out of those 2 wavelengths listed. Which one will be better for beam visibility and beam distance at night? And will a beam expander help with long distance pointing? Thank you. Chris
