I am doing some research on a DIY add on for my 3d printer for a laser engraver. I do not know much about lasers other than the higher the MW the more powerful the laser. I am currently looking at these two laser modules

One is a 5v 1600mw laser and the other is a 12v 500mw. Does the difference in voltage change anything? even though the 1600mw is the higher power laser, does the lower voltage change anything?
Thanks.
