I have been looking around the forums for several days, but so far have not found a beamshot comparison between the original 200 lumen SF E2D LED (which I own) and the newer 500 lumen SF E2D LED Ultra (which I covet). Anybody out there with both, or maybe I've missed a repository of beamshots I could consult? I know I want the newer model, but since my current model is already the brightest torch anybody in my personal circles has ever seen, it is hard to get my head around what the practical difference would be if I upgraded. Apologies in advance if I have missed something obvious - if accepted, this will be my 3rd post (I think). Thanks very much. pxd London
