The Fenix TK16 V2 has APF technology. What is APF technology?

First of all, we would like to share that this APF technology is leading the flashlight industry for at least 2-3 years. 

The benefits of APF and what it does:

The APF (Advanced Pulse-Frequency Transmission System) was developed by Fenix laboratory, a major technology breakthrough in the flashlight industry. It allows the tactical flashlight to achieve a higher level of performance:

1. Take light to the extreme. Traditional forward switches are limited by current, and it is difficult to achieve brightness above 2200 lumens. In the age of 21700 batteries gradually expanding, 3000-lumen tactical flashlights are almost impossible; but APF technology makes it possible.

2. Make the functional tail cap simpler. Traditional multi-functional tail cap needs to achieve functionality through the double-layer body or additional channels; and the flashlight using APF technology offers a strong reliable flashlight in simple structure, specifically through a single layer body.

3. The Anti-magnetic interference ability is based on mechanical switches which are more reliable than the Hall effect switches. The advantage of the TK11 TAC mechanical switch is based on point 2.
