Constant current circuit and non-constant current circuit
Fenix products use two kinds of circuits, one is constant current circuit, the other is non constant current circuit
Constant current circuit
It refers to that in the process of using the flashlight, through the intelligent adjustment of the circuit, the flashlight always keeps stable light output. Our designers have developed excellent constant current circuit, leading the industry in photoelectric conversion efficiency, so that the limited electric energy can be converted into light energy to keep the brightness stable, providing continuous protection for your journey.
Non constant current circuit
It refers to that with the consumption of battery power, the light output of the flashlight is gradually reduced, so as to ensure more durable service
