I guess I should update this for the Godox-Witsro units. Measured GN (ISO 100) is about 200' with the standard reflector -- I'm currently measuring the Norman 2H with the Norman spacer but the tube socket in the Godox is recessed more deeply on the Godox than on the Lumedyne/Norman units and I need to make a longer spacer (I am going to try the Q-Flash tele flash tube spacer as it is longer and see). With the 2H and Norman spacer I am getting a 1 stop increase but it is clearly NOT optimized! I'll add more later....
