No it’s not lol they still flicker out eyes just dont pick it up

It has a 60Hz electric waveform in, and it produces visible light, which is in part a ~500THz wave.

Do you think we will ever change our power grid to have a higher frequency so that our bulbs don’t flicker when we record things?

Incandescent bulbs like that in the picture don’t really flicker. They might pulsate a little bit but even at their faintest they would still have significant light output.
Some LED bulbs do flicker though, it depends on how they implement the AC to DC conversion. If they flicker, it is easily noticeable to the human eye, especially when looking at motion.

For incandescent bulbs the power drop around the zero voltage cross doesn’t last long enough to extinguish the filament, since it’s basically just glowing from being heated. The only lights which actually do “flicker” under nominal conditions are old ballast driven florescent lights. Most modern LEDs rectify the AC and modern CFLs boost the line frequency to like 20kHz to prevent the arc from getting extinguished.

Modern CFLs use an arc? I thought they were cathode based, emitting UV from forcing mercury vapour to dance

A lot of christmas lights still flicker. Not sure how they’re wired, but I think they just feed AC to the diode, so it’s off for the negative half of the wave

Flickering lights used to mean a temporary < 1s power outage.
