Firstly let me nail my colors to the mast and say that I am asking because I really do not have a clue what I am talking about here, and would like to be able to draw better comparisons. So for example.
Is one class 4 beam laser better than, equal to or worse than two class 3 beam lasers? Likewise one class 3 beam laser v two class 2 beam lasers.
I have often wondered if was was a case of class 4 being worth 4, and class 3 being worth 3, so two class 3 = 6, and so being better than one class 4. However I am probably looking at it all wrong. So how can they be compared?
