Flashlight Science: PWM Explained & Demonstrated. How to Detect Pulse Width Modulation in Lighting
Published: 8 years ago
A lot of people ask me, what is PWM, and why is it important to bring up when reviewing flashlights? PWM is something a lot of flashlight reviewers talk about but not many explain. In this video I demonstrate how to detect low frequency PWM in videos and photos. No one wants visible PWM in their high end tactical flashlight, so watch this video to find out what it is and how to detect it. Not all PWM is bad or visible- a lot of good flashlights are programmed to use very high frequency PWM to your eye and your camera doesn't detect it. Anyway, thanks for watching this flashlight science video.
