I just got a Fenix L0D in the mail today. Quite bright for a single AAA and, I hesitate to say this, it's cute. The L0D is a very small, keychain size light, a bit longer but sleeker than the smallest Streamlight.
It looks like it would grow up to be a P3D if I fed it enough electricity <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
