Meridian 45 rolling pattern using camera

[exnisstech]

Not sure what to call but I just set up a meridian 45 and when I try to use a camera I get a rolling change of light. It reminds me if an old film projector slapping the end of a roll of film over and over for lack of a better description. Young folks may not get it. I have a lot of different lights including a meridian 11 and this is the only light that causes this. I've changed light setting and used filters with no change.
I figure it must have something to do with the leds but am curious since it's only this one light.

is this the same light that you have @VintageReefer ?

That’s crazy, I don’t get that effect on video. Can You record in a different fps or hz?

Most LEDs use pwm to dim LEDs.
This can cause the effect you see depending on shutter speed and pwm frequency.
The frequency is usually software determined.
If all channels are at 100 ( or 0) you normally won't see it
Many use (d) like 500-ish hz.

It's the frequency of the LEDs turning on and off that your camera is capturing.
