Correct me if i'm wrong.
the true is more likely to be close to the spec the true 30mW it will be about 25-30+
the other wich is not true it will be about 20.but if you want a cheap one buy their true 5mW,it can go more than 30mW.
no their 5mW is always overspec.i have read one had go more than 50mW.
thats what the manafacturer makes it.also DX they don't test their lasers so they don't know if is more than 5mW and sell them as ~30.
i'm not sure if it will be 50mW but you can potmod it.john when he potmod one i think it was 70-75mW.
if you think you will brake the 5mW trying to potmod it buy the 50mW.
