What is APFUpdated a year ago

The APF (Advanced Pulse-Frequency Transmission System) was developed by the Fenix laboratory and is a major technology breakthrough of flashlight industry. Allowing the tactical flashlight to achieve a higher level of performance in the following ways: Traditional forward switches are limited by current, and it is difficult to achieve brightness above 1000 Lumens with 18650 batteries and 2000 even with 21700 batteries. APF technology allows these limits to be surpassed Make the functional tail cap simpler. Traditional multi-function tail cap needs a double-layer body or additional channels to work. APF technology offers a more simple approach to meet these goals. Better anti-interference performance. Complex external environments such as strong magnetic fields are easily ignored because of stronger anti-interference ability.
