R2 dropin strobes under camera?

Im not sure what is going on. I think it might be my camera's frame rate? can anyone explain why my R2 blinks/strobes under mid and low settings? Is this inherent to how the dropin regulates the light and lowers the brightness?

watch the video.

here is the drop in that i bought

Exactly as you said in the video, the frame rate of your camera is showing up the Pulse-width modulation of the drop in.

Nice. that was quick. thank you.

Frame rate of cam synch-ing in and out with the modules PWM frequency. My vids show it as well.

**edit**
WOW yours looks like a strobe...LOL

Wow, that looked like the strobe on my L0D Q4.

yeah I know. when you watch the video and I switch from LOW to strobe. there doesnt seem to be ANY difference haha.

If you are seeing the strobe effect when its not in "strobe" mode with your eyes, its not the camera causing it. Are you seeing this with your eyes when looking at the light in the lower modes?

If so, are you using RCR batteries that bump up the voltage above 6V to 8.4V?

The 5 mode R2 pills that I had from Lighthound did not have the voltage range capability of the single mode. With higher voltage in lower modes it actually did flicker. When I used primaries that were 6V or less (total) then the flickering went away.

The pill may say its good to run at up to 8.4V but the reality is with freshly charged RCR123s in low mode that draws less current it flickers because its at the very end of the regulation range for the incoming voltage.

If you try to primary batteries and the problem goes away its your pill and not your camera. I got rid of all my five mode R2 pills.

no Im using primaries. the flicker/strobing only shows up on camera.

x2.. my findings as well.

then its pulse width modulated at a rate that you eye integrates it and sees it as a lower level but the camera frame rate catches it for what it is. Buy a different type of module. I have never seen this in any of my videos with the Malkoffs, Fenix's, Eagletacs.
