nothing wrong with the LED's they are just pulse width modulated at a frequency that is not working with the FPS of the camera. Much like an old computer or TV tube when filmed.

If the light fluctuations are sufficiently rapid, the human visual system can no longer resolve them and the eye perceives the time average intensity without flicker (see flicker fusion threshold).
