The issue is not with LED lights per say, but because most of them are made so cheaply with insufficient heatsinking, and capacitors too small that they end up flickering, overheating and dying way sooner than they should.
Followed for the hype, unfollowed for the ScIeNCe. Saccades mean your eyes constantly flicker the signal to your brain on and off. That is just how your eyes work. Your brain fills in the gaps with predictions of what it guessed was in those gaps to create smooth movement in your vision. Don't believe me? Go watch TV. It is just a series of still images at a rate that the saccade rate causes your brain to perceive as movement You literally would be a melting ball of stress every second of every day spent awake under every type of light source if flickering stressed you out. Think about how amazing your brain is to constantly and accurately fill in those gaps in your vision. Far cooler than BS influencer ScIeNCe.
Kruse is another quack and I've wasted far too much time posting rebuttals to his BS also. I will not be drawn in to having more of my brain cells killed by his garbage by clicking that link. I'll leave it at standing in the sun the light on a clear day is several orders of magnitude greater than your cell phone pressed directly against your eyeball. If you get any morning real sunlight even your TV is nowhere near bright enough to override that signal. Only putting your face against 100w or 200w LED plant lights is close to a substitute. Get a lux meter app for your phone and check for yourself instead of listening to snake oil salesmen. The reason being on my phone too close to bed keeps me up at night is because I see stupid shit like this and get pissed off.

Nothing beats daylight, but have you considered that for over 50 years, billions of people have been living and working under fluorescent tubes, that have way worse flickering than LED, yet nobody seems to have noticed, let alone suffered...

LEDs need a current source as opposed to a voltage source. With proper heatsinking and a constrained current they will do just fine. The issue is that bulb manufacturers cut the corners.

If you just hook a LED to mains with a resistor you get the flickering from the AC supply. To get rid of the flickering you need to remove the 60 Hz component through DC conversion one way or the other. Much higher PWM control (e.g. 20kHz) is fine too. What can be annoying with LEDs also is how much a point source they are vs incadescent bulbs, which tends to create undesired shadows. They need to be either diffused through a diffuser or a reflector, or you need multiple of them.

wow the boomers must be loving your content electricity be scary brah
If the government actually cared about saving energy, we would stip using central air. Lighting is a very small portion of energy use. And incandescent is much better for your eyes. Stock up while you can.
