Affirmative:) A funny thing that when I'm playing with it and my surefire. I shot the laser to glass and some light reflect to my eye, the feel just like looking to a small light bulb, nothing hurt. But the same thing happen with my surefire, I just feel pain and there is a black area appear...

11mW really danger:cryyy: but i still cant find any class 1 on sale, maybe that is really useless:angel: excluding the power meter, is there any way to know how powerful is a laser? just like calculating or something else?

Yup, there is one. And I'm going to put a 100om for limiting the strongest current and one 100om variable resistor for tuning the intensity to suit different enviroment. I wonder why such device required three 1.5V batteries but not two. I have tried to use one CR123A to drive it, and it works...

Thank you so much. So I am going to start my experiment now :)

Oh thanks!! Actually it really not like a "diode" that I've even seen. :P I am a wargame player, and I want to mount a laser pointer on my gun, but I cant found any class 1 laser on street. So I want to lower the power of these cheap things so that I wont hurt any others eyes. One more thing I...
