The beam can be oval or 'not round' and still be flawless. By this SureFire means without rings or dark spots or holes in the beam.
The High Output Lamp Assemblies tend to have rounder beam the the standard Lamps because the filaments are shorter and fatter and less likely to be curved. The E Series bulbs are exceptions - the MN01 and MN03 are very round beams from my experience and from all that I've read.
