All in all, the processing of the Fenix prima, it lights more than bright and you can choose between 3 different turn lighting levels.
This is of course quite well to save energy.
Added to this is the SOS mode in which the lamp kontinierlich the SOS Siganl shines and the strobe mode, which should be very useful to Selbstverteidungszwecken.
Here, the light will flash in a split second in time interval which can dazzle anyone really nasty.
