Best signal laser

[CyberWraith]

So I'm pretty sure a green laser would be the best for signalling but just checking cause it is the brightest out of all of them correct?

What are you trying to do signaling for? A spotlight is probably a better choice. Better yet, use a phone?

If your signal,ing the alien ship they prefer uv. Use a 405nm.
