Hey back (and sorry for all people disturbing about that "I will soon do a purchase and soon price will go down that's why would know all information before purchase" )
So, first I would said thanks to everybody here I now understand about "nm" who is "frequence and wave about color"
but I still not understand about
mW between two identics laser same nm one 1 000mW another 5 000mW or more
I would know it will change powerfull and brightness or just capacity of battery without need to recharge
for exemple (sorry it's not to do add sorry if link should not be done)
5 000 000MW 450nm
500 000mw 450nm
between these two for exemple what the real difference ?
also does I need glasses everytime ? if yes what glasses should I bought?
Hope this post will not disturb I need to know more this forum he look like giant
thanks again to accept it and for your help
