The beam shape and light distribution of SureFires are carefully designed to increase your effectiveness in low light / no light "tactical" situations. My understanding is that research leads SureFire away from tight beams for shorter range illumination tools (such as two cell SF123A models) because they can disadvantage users.
Me myself personally don't need no tactical advantage so tight beams are a preference. However, I've found that when actually using light, for all but spot illumination at range, tigher beams are less useful to me.
What I want is a close range lower intensity flood beam and a high output intense narrow beam for longer range (from a single bezel rechargeable flashlight, built like a brick chickenhut and the size of an M2/M3 with a high quality pocketclip or various other carry methods.)
