It has nothing to do with the artificial light, that's a different setting. The frame rate must match the refreshing rate of the display where the video is played, according to the mains frequency. For example, my computer's video card can handle 1080p 50fps with absolutely no problems at all but if I try to play a 1080p 60fps video it plays 2 secs, starts refreshing, plays another 2 secs, starts refreshing, and the vicious cycle goes on and on.I lice in 50 Hz country but use 30, 50 , 120 , 240.
But it is also rare i have a artificial light source in my footage, or anything else synced up to our 50 Hz AC

My graphics card doesn't have any reference to which FPS are supported but I assume that if it's working on a 50Hz-based power grid it should be 25fps.This just means your computer can't handle 1080p 60fps and has nothing to do with a requirement that the fps match the refresh rate of the monitor. If your graphics card is running at a higher fps that your display can handle it can cause tearing in the video but won't cause pauses. Also, many displays have higher refresh rates than the frequency of the incoming electricity.
If, as you say, it doesn't matter, then can you explain why would Foxeer bother to provide the frame rate options of 25, 50 and 100fps? If, as you say, it doesn't matter, Foxeer users would never chose 25, 50 or 100fps, since 30, 60 and 120 have more frames per second. It seems a bit pointless, doesn't it, but they do it for a reason.CRT TV vs led computer monitor, yes some standards are still used, but your computer and monitor are not effected by tv standards. Games are often played at 60+ fps depending on the hardware. LED monitors are capable of 30 - 240hz refresh rates but your computer has to be able to handle it as well. My graphics card will push many games at 120fps or more but my monitor maxes out at 120hz. Neither is effected by the scan rate of old crt's.
