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

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.

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

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!

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.
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.
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
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
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.
I buy the cheap $3 boxes of colored lights. They aren't that bright and give a nice warm color to a room
