Hi all,
I’m trying to find good, strong-light, zoomable flashlight, used with 2 26650 batteries.
my son wants to connect it to his telephoto camera of him.
We bought the “HaikeLite HT35 XHP35” but it is blinking all the time so he can’t take photo with it.
Thank you for your help and forgive me for the poor english….
Pulse Width Modulation. A technique of varying the brightness of a LED by flashing it on and off very quickly, making it appear to the eye that the LED is dimmer. Good PWM is at such a high rate that you can’t notice it. But if you wave your hand in front of the light and get a strobe effect, the PWM is getting too low. Some use current regulation which makes the light dimmer without PWM and is also more efficient.
