which one is better?
laser pen or industrial type ? (same mw)
i've heard that green are more visible than red, if i compare 150mw red with 100mw green, how is it?
because i have 30mw green and 100mw green are about the same visibility.. :thinking:

Comparing a labby to a portable is like comparing apples and oranges.
