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.
Did I read the story?
Yes I know it doesn’t discourage the use of 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
I can't recall seeing any legal head or tail lights that have flickering issues. We will hopefully see this issue less and less as people are no longer allowed to buy the illegal retrofit kits from places that sell headlights. We've seen a lot less people running the Sylvania super bright off-road lights now that you're not allowed to buy them from the headlight section of an auto parts store and online stores are not allowed to sell them without off-road use popup warnings.
I really wish that instead of useless trash like drunk driver checkpoints midweek we would start seeing headlight inspection points or other vehicle inspection points to check for safety issues like these; if we're going to keep having these checkpoints for no reason.
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.
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.
They must have watched this video https://youtu.be/va1rzP2xIx4?feature=shared
Lol was wondering if someone would post his video
I came here for Technology Comnections, and found it.
Thanks. I was just reading about the flicker of different LEDs this morning due to my similar distaste for the lack of warmth with current Christmas lights.
Oh, and direct link to article here. https://www.npr.org/2023/12/22/1198908957/led-lights-flicker-headache
Newer LED lights often flicker.
Saved you a click.
That's not so much the LEDs themselves, as the cheaply designed power supply.
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.
what a fucking boring world we've made. Flashing lights give people seizures and shit, but sure, we can just pretend that's not a problem and make all the lights flicker instead of learning how to make an LED dimmer. Fuck it! Obviously nothing matters anyway. That's what we as a society are apparently saying. Woo, capitalism.
You know incandescent bulbs flicker, right? Same with CRTs. The bulbs flicker at ~60Hz. CRTs at ~30 fps.
I'm not saying flickering isn't a problem but don't act like things didn't flicker before.
Incandescent bulbs don't visibly immediately transition to a harsh on/off state like LEDs do when operating at the same frequency.
Incandescent bulbs are still burning and emitting light during that brief period of "off" time, and CRTs have a similar "effect" that allow the interlaced lines to display smoothly on the screen AFAIK, although I will admit CRT flicker is much more noticeable
Fluorescent lights are the absolute worst with the flickering, and they have been around for decades. I actually prefer LEDs because they seem to be able to output a wider range of light, instead of making everything look yellow, which is where the "warm glow" comes from.
I buy the cheap $3 boxes of colored lights. They aren't that bright and give a nice warm color to a room
I still use the old school ceramic C9 bulbs. So much better. They give off a warm colorful feeling. Led lights just feel cold to me.
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.
Have you tried a high refresh rate monitor? I doubt you’d see the flickering at 165hz or 240hz.
LCD monitors don't flicker at their refresh rate. It simply updates the graphics on the panel per frame at an imperceptible speed. The backlight has nothing to do with the refresh, either.
This isn't true for all of them. Some have a backlight strobing feature that flashes the display at their current refresh rate to reduce motion blur. It makes the strobing much worse at lower refresh rates, though.
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.
