That story explains why I dislike led lights
Thank, NPR, for mentioning migraines as one of the problems.
Now do an article on flickering, eye-piercing, migraine-inducing LED lights on emergency vehicles and crosswalks.
If there are any lights that are understandably bright, it’s those on emergency vehicles.
The bright-ass LED lights on liften trucks though are entirely infuriating.
It’s not the brightness that’s the problem. It’s the sharpness and the strobe. Back in the old days, when they were spinning lights, they were nice and bright and got the job done just fine without those two aspects.
Hell, even as annoying as the xenon strobes were, they were never anywhere near as disorienting as the LED strobes on the emergency vehicles now. That and the low sound range sirens… They make me nauseous when they pass close by.

I love that I get this reference.
I also love that last year he found a company manufacturing strings of white LEDs with colored tips (which is his ideal setup) and said he probably wouldn’t need to make any more annual videos about it anymore.
Cue this year’s video about it lol
✋😐
I grew up with incandescent bulbs, and it was hell. The waste, in both trash and energy consumption, was horrendous.
The (thankfully) short age of flourescent reduced energy use, but the trash was worse, and the light categorically regressive.
LEDs are, in all ways, superior. You buy cheap-ass crap LEDs, you’re going to get a worse experience, obviously. Despite some negatives, LEDs are still the best lighting technology available. Feel free to complain, but there’s no better option right now. Wanting to go back to incandescents is vinyl-turntable-level, selective memory, retro hipsterism. And also super shitty for the environment.
We may be annoying, but we’re right damnit!
But did you read the story? It doesn’t discourage use of LED products. The issue is specific LEDs that are manufactured with sub par components that contribute to flicker. Unfortunately it’s the only thing regulation will solve. Personally I’m waiting for headlights to be regulated for glare, position, and color temperature.
Has anyone here tried https://tru-tone.com/
The ads make them look like the colours of my youth, but ads can make anything look like anything…
Actually yes! I got some this year and they’re fantastic. Aside from the fact that they don’t get hot, they are indistinguishable to my eye from incandescent C7s.
Ooh! That’s great to hear! A real glowing review… I’ll probably snag some before next Christmas!
Never heard of them but I am going to look into them.
You can too often see the same thing in LED car headlights and tail lights. The most obnoxious of these flicker noticeably all the time. Not much better are the ones that seem to be on continuously when viewed in the center of your vision, but flicker in your peripheral vision. The later I find really distracting
On digital rear view mirrors you can really see the flicker on some headlights and DRL because of the framerate of the camera. Most cars are fine but some aftermarket headlights and GMC/Chevy(IIRC) are very noticable.
Couldn’t work out for months why I got a blinding headache on a building site at about 2pm every day in winter, until spring came and we didn’t need the LED work lamps any more
This shit is definitely real
Those deep blue LED Xmas lights are the worst for whatever reason.
About 75% of LED monitors give me a headache because I can see or “feel” then flickering. It sucks.
I had a coworker back in the in-office days who had these garbage-ass monitors and whenever I had to pair with him I’d end up with a debilitating headache.
I have sensitivity to certain lighting and find amber glasses help me a lot. I don’t know if it’s the same as your issue, but it’s be worth trying. I first tried it with a pair of $10 clip ons I bought at the hardware store. They were meant for highlighting contrast for outdoor activities. One since gotten prescription glasses with amber lenses for work.
Theraspecs have various tints as well! I wear rose-tinted (FL41) lenses that were specifically designed to help with light sensitivity and photo phobia. Since changing to a rose lens, I can make it through a day at work with flourescent lights and through a 2 hour music rehearsal at a school with flourescent lights, whereas that would be exhausting before and cause headaches.
Is there a good eink monitor yet? I think I saw boox made one but I was not sure it was large enough or useful yet.
Have you tried a high refresh rate monitor? I doubt you’d see the flickering at 165hz or 240hz.
This article seems sus to me. It describes a bunch of ways to observe high-frequency flicker that, IME, just aren’t a problem. Personally I find flicker stops being a problem above about 60 Hz. I’m sure the threshold varies for different people, but I can’t fathom how anyone could be bothered by a 2000 Hz flicker as the article seems to suggest.
Also, for reference, back before first screen TVs, TVs all flickered at 50 or 60 Hz depending on what country you were in.
I love how you decided it doesn’t exist because you personally don’t notice. Lighting design is a thing.
This is like those people who don’t get headaches and nausea when they watch 3D movies telling people who do get headaches and nausea from watching 3D movies that “it’s not that bad!”
Nice job misrepresenting what I said.
They stated “IME” and “personally”, understanding thresholds vary per person… but you gloss over that just to try and create an argument. I bet you have blue hair.
The upthread comment says:

What does this part of your comment mean?
I bet you have blue hair.
You could hear a 2kHz flicker. It would hurt my head for that reason. I also have certain monitors and earbuds that I can hear the power led and hate it.
Personally I find flicker stops being a problem above about 60 Hz.
The standard AC frequency in the U.S. is 60 Hz, so…
I meant at or above. I never had problems with NTSC displays running at 60 Hz.
LEDs in general aren’t good for your mental health either. Unless it’s an organic screen (OLED), you’re getting too much blues in your lighting and it will make you crave sunlight. They’ve known this for decades. In the winter, get outside more, not less, you need the full spectrum of the sun.
i thought i read something about a new blue oled (pholed) that was supposed to bring it into some parity with the other 2 in the oled space… so that may not be a source of ‘less blue’ in the future
I looked into it, thanks for the heads up. https://www.digitaltrends.com/home-theater/what-is-pholed/
My guess is that companies want to call themselves OLED and charge those prices while giving an inferior light source. People will spend the money and not get the value from it, the gorgeous colors they can’t get to.
