While we're talking 1xAAA lights, my latest pocket EDC light is a a Fenix E05 (just recently discontinued, I believe but some places still have stock). The flood optic on it gives a big, bright, even beam that is very useful for short distance lighting situations. Twisty switch, O-rings, not much to go wrong with it. Brighter than an E01, which can be too dim in situations where you have stray ambient light to compete with. Of course, you get shorter runtime than an E01, too.
