That story explains why I dislike led lights

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

[–] Zanz@lemmy.world 8 points 11 months ago

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.

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.

[–] RGB3x3@lemmy.world 34 points 10 months ago (1 children)

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.

[–] fsr1967@lemmy.world 15 points 10 months ago (1 children)

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.

[–] boeman@lemmy.world 7 points 10 months ago

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 came here for Technology Comnections, and found it.

[–] geogle@lemmy.world 29 points 11 months ago (1 children)

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

[–] pelespirit@sh.itjust.works 10 points 11 months ago (2 children)

The lack of warmth is the color of LEDs, they are based on blues and no reds because of cost and efficiency. In places where you get a lot of sun in the US (Arizona, Southern Cali, etc.), I bet the blues are loved.

[–] AnneBonny@lemmy.dbzer0.com 11 points 11 months ago (11 children)

Yeah, but you can buy LEDs with different temperatures.

My reds on my Christmas lights are not comforting either.. Oh, and I live in the South with plenty of sunlight...

Newer LED lights often flicker.

Saved you a click.

[–] kent_eh@lemmy.ca 2 points 10 months ago

That's not so much the LEDs themselves, as the cheaply designed power supply.

[–] psycotica0@lemmy.ca 16 points 10 months ago (2 children)

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...

[–] Corgana@startrek.website 5 points 10 months ago (1 children)

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.

[–] psycotica0@lemmy.ca 3 points 10 months ago

Ooh! That's great to hear! A real glowing review... I'll probably snag some before next Christmas!

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.

[–] Alexstarfire@lemmy.world 6 points 10 months ago (2 children)

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.

[–] uid0gid0@lemmy.world 3 points 10 months ago

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.

[–] lemann@lemmy.dbzer0.com 3 points 10 months ago

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

[–] Mr_Blott@lemmy.world 3 points 10 months ago

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

[–] Billy_Gnosis@lemmy.world 3 points 11 months ago

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.

[–] AlecSadler@lemmy.ml 2 points 11 months ago (2 children)

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.

[–] Akuchimoya@startrek.website 2 points 10 months ago (1 children)

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.

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.
