I have a 1000mw 445 blue laser and look to be ordering a 500mw 405 violet laser. As I understand it the violet is much dimmer because it has 1/2 the output and the human eye is far less responsive to violet light. I ask anyone that has both if they wouldn't mind describing the difference. I am not into burning lasers; I just like how they look shining into the sky on a dark night.
