It's the idea of the center hotspot that I don't like. In situations where the L4 is truly in its element, like when looking around under the hood of a car, the spill from my E2DL is probably brighter than the spill from my L4. The problem is you can't keep your eyes off of the hotspot, and find yourself constantly moving the light around to center the hotspot on whatever you're trying to see. With the L4, the alternator is just as brightly lit as the valve cover, without moving the light. Wouldn't it have been nice if Surefire had taken the extra output of the new emitter and distributed it evenly throughout the beam?
