Apples to Oranges Onyz, but...
My 5D light is a Brinkmann 5-3-2 light. It has 6 C cells in it and that particular light has a nice bright pretty smooth beam. It doesnt tell us exactly how a Mag would act, but...
My 4D Mag has 5 C cells driving a KPR113. It is good but considerably more ringy and artifacty.
My 3D Mag has a new Xenon Star bulb and three new Energizers. It has a beam with a very smooth center and not many artifacts.
If you did 6 Cs and used some sort of film on the lense I think you would have the best of both worlds.
