Everytime I point a digital camera of some sort (webcam, phone, camcorder...) at my LED desk lamp or its light reflected off an object (only if the object is very reflective and/or near the lamp), I see some scrolling black lines that shift thickness and scrolling speed as I change white balance.

They make it impossible for me to film uboxing and other videos using my desk lamp as light source. What is the cause of this? I also noticed my ceiling-mounted LED light produces a similar pattern as well albeit with thicker lines. Finally, my bedside lamp - also LED - creates no such phenomenon.
