Laserwave 500mw 520nm mini review.
The first difference is the new smaller module driver dimensions, and the module head is little bit higher dimensions than older Oem pro 638 / 450nm module.
So, the green light power is impressive, but the beam point around is dirty, but the filters and dichroic mirrors scanner after reduced the dirty light,
but not clean the figure.
Module worked about one hour and the module head and driver little bit warm and light power is stable.
Overall good, but in the future recommended to LW repair eliminating the dirt beam.
