Heavy flickering on 50Hz&60Hz

Hello

I'm pretty new into streaming and I wanna show some technical videos.
But it seems that my Logitech C920 HD can't handle my LED spotlight.
I browsed a bit through the net and had a look at a bunch of "flckering" solutions.... but they only solve this mini flickering effect.
I had that too on my overview camera and there did the 50Hz setting help.
Have a look at this quick example video that I made.
YouTube: Flickering issue
Effect visible at 00:25
Anyone got an Idea how this could be solved?

Kind regards

Well, it was just an idea to look at...I have no idea what the problem could be.
I just subscribe to him on YT and that came along not long ago..
 
I found now a temporary solution.
As table surface I need a black bachground.... the dark grey seems to be already reflecting too much light and the camera can't handle that. :/
 
My C920's continuously focus on wood desktop but it's O.K. on a white background..
I find it better to just leave auto focus off at times...
Keep posting on any progress or ideas you may discover...
 
I just wanted to update this case.
I installed now a waaaay weaker spotlight. Went from 8000 lumen to 225 lumen....
Now it works.
It seems the webcam C920 can't handle too much light and starts then flickering.

I did choose a strong light, since the parts I want to show are basicall black in black.
So I wanted a very good illumination.
But now I use a black background and a weaker light.
Then there shouldn't be too much light differences.... hopefully that works.
