In the thread I posted the link above, the OP reflector lowered throw 8 meters. This is on a C8. If you sandblast or diffuse a lens, the beam is smoother, but you are blocking the light out of the front. With an orange peel reflector, and a clear lens, the light is all going out the front, just not all in the same direction.
I like OP, but smooth and diffused have their place too…
