First off, WELCOME ( that's a big welcome!!) and there's plenty of help here. I don't have a Scorpion or the SF E2E but I believe the output is around the same (lumens) as is the run time, but the beam picture may be different. The E2E does not have a focusing bezel (not a big deal anyway as most focusing bezels do a poor job of providing a multipurpose beam anyway) but has the benefit of being narrower than the Scorpion, has a pocket clip, a lower output lamp availiable with longer runtime, a solid lock-out tailcap to avoid accidental discharge, a mil-spec HAIII finish ( the fit and finish of the SF lights is great) An optional Kl-1 LED conversion bezel (much longer runtime), numerous colored filters and beamshapers avaliable along with various accessories and a "you break it we fix it" guarrantee. Anyhoo you should be getting the picture by now. Others probably have comments and corrections for me. And you should search for beamshots and reviews (as well as links to others review sites) of all the lights you consider as well. Good luck and enjoy!!!
