The D25C XML has been my go-to EDC light for the past 9 months or so, with no end in sight. At first I used 16340 batteries, but now use standard CR123A primaries, and prefer the extended run time and find the Medium setting useful. I don't miss the extra output at all either.
I keep it in Moonlight off mode, as the normal Low setting is VERY useful, but it's easy to switch back and forth between Moonlight on and Moonlight off modes. I keep a D25A XML in my nightstand in Moonlight on mode which is perfect for that use.
Anyway, my D25C is always in my front left pocket unless I'm at work (where I have a G25C2 on my belt) or asleep.
