Such a sad story! Thank you and the others for clarification. I've returned pot back - now I can see only a small spot - may be just a little bit lighter than by default, but the same size. Beam is hardly viewable even in pitch black night sky. I think now it should be somewhere near 3-5mW. By...

Sure. With 3V on battery it's more than 3W in you case. However, actual voltage should be much lower, I think.

What about relative change? I mean, if I slightly increase power by turning the pot from default position and count the change in battery power drain between these two pot positions does that difference somehow reflect difference between power levels of beam?

So you think I will get nothing of it? By the way, concerning warnings about near death of my pointer - Laserglow sells wide range of the same model for different power levels up to 50mW. Do they do something special for them to prolog their life? I have doubts.

Thank you so much! It so simple that I wouldn't ever think about it. But actual power of beam, of'course, should be slightly less than the multimeter shows, right? Excellent solution for me, anyway.

Actually, I didn't want to "pot mod" anything. I just need stable but safe pointer. If somebody can give me some hints about some approximate measurement of a real power I have, it would be appreciated. The only thing I can say is that today I can't feel any heat from long lasting beam, pointed...

Hi. I'm a new owner of a 589 laser - Laserglow Rigel HV-2 (5mW) - As far as I know it's a CNI (may be slightly tuned). By an accident (I dropped it) I got inside of it and found a small potentiometer. For other users - don't try to open it! Enclosure attached by the glue and it is not a trivial...
