The Fenix P1D is a digitally controlled constant current multilevel flashlight Fenix has to offer. It has five modes: Primary -> Max -> Low -> Strobe Mode -> SOS Mode, which not only allows the user to select the best compromise between brightness and runtime for any given task but also has ability to aid in an emergency. The P1D does all this and still retains a very compact size. If you're looking for solid reliability, digitally regulated brightness, and compact size, this Fenix is for you.
