10 Watt Blue 445nm Handheld Laser. | Laser Pointer Forums ...
Jun 12, 2016· Not 10 watts, no way, not with those batteries. Possibly 2.5 watts, and that's not bad for desktop burning/cutting, but it's not going to be 10 watts. At the very best it could be a 5 watt, but I doubt it judging from the focal point, it looks like a NDB7875 with a 3 element, they are good burners/cutters on the desktop.
