I have 2-100mw green modules from o-like and 1 gatlin 200mw green laser from a member here who shall remain nameless,but for the life of me i can not see a difference in beam brightness at all.I also have 2 50mw modules from o-like and the difference is striking between 50mw and 100mw.But i am only using a 3v battery for this host maybe that could be the problem.What do you guys think.
