You may want to be careful and use the manual lockout on the EA11, when not in use (about a quarter twist of the tail cap, to manually lock out), so you don't find yourself with a non-functioning light, when you need it the most. That's happened to me, more times than I care to admit, even in its holster (while stored in a bag). Mine served me very well, but I haven't used it in a while. I ended up opting for the Zebralight SC600w Mk III, which isn't much larger, but gives comparatively tremendous run times and nice, neutral output. The EA11 is not known for stellar run times, but has very impressive output (albeit short-lasted), for such a small light. Direct access to low, turbo, strobe, or red light, is also a nice touch. It also projects surprisingly well, for a light of its size.
