How do I stop my iPhone from flickering in slow motion?

What is flicker reduction 50Hz or 60Hz?
Flicker reduction can detect flicker at 100 and 120 Hz (associated respectively with AC power supplies of 50 or 60 Hz). Flicker may not be detected or the desired results may not be achieved with dark backgrounds, bright light sources, or other non-standard lighting.
Why do lights flicker on camera?
LEDs are powered by alternating current, AC, in which electrons in the electricity move in and out of the circuit in cycles.When the frequency of the camera’s frame rate per second (FPS) and the LEDs don’t quite match, the flicker becomes visible on the camera screen.
What is the minimum refresh rate to avoid flickering?
A refresh rate of 60 Hz on most screens will produce a visible “flickering” effect. Most people find that refresh rates of 70–90 Hz and above enable flicker-free viewing on CRTs. Use of refresh rates above 120 Hz is uncommon, as they provide little noticeable flicker reduction and limit available resolution.

Why do lights flicker on iPhone video?
Flickering is often a result of the desynchronization between the shutter speed/frame rate of the camera and the frequency of the AC power that the lights are plugged in to. A solution is to use a shutter speed/frame rate that is slower than the frequency of the AC power.
How do I stop my slow motion video from flickering?
Regular incandescent light bulbs flicker because the heating element cools and heats up by the factor of the 50Hz-60Hz refresh from the electric current. The trick in Slow motion capture is to find a light source where the flicker frequency is not lower than the refresh rate of the camera sensor.
Why does my camera flicker on slow motion?
The frequency of each video frame is far higher than the frequency of such lights. As a result, some frames of the videos are shot when the light is on while others are shot when the light is off. This is what causes flickering or ripples to appear in videos.
