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.
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.
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.
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.
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
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.
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.
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.
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.
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.
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
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.
As a Jew (and an atheist) who never grew up celebrating Christmas but having it forced down my throat for two months of the year anyway, they’ve always given me a headache.
I don’t mind that people celebrate Christmas in general, it’s just that it’s so overboard.
EDIT: I knew a bunch of people would downvote me for finding the two months of the year they shove their religion’s holiday down other people’s throats going overboard.
I never really noticed the lights as a Christmas-specific problem, between Diwali, New Year, and Lunar New year, there’s lights up from October to February in my country.
So as a migraine sufferer who does have issues with flickering LEDs at night (particularly the blue or blue-white diodes) I can’t blame Christmas alone for my pain.
But the carols! The fucking carols! I’m far more sound sensitive than I am noise sensitive with my migraines, and the vast majority of the “classic” Christmas carols just hit all the wrong tones for me. High pitched bells, weird twanging piano keys, blasting from speakers when I’m just popping into the shops to buy dunny roll, it’s awful. One of my jobs is a choir facilitator for an intellectual disability program, and this time of year is a walking nightmare because it’s carols, all carols, nothing but carols (and any attempt at musical redirection is a recipe for unhappy clients), I think I’m single handedly keeping my local chemist in business with my migraine med scripts.
I wear ear plugs where I can, but the pressure of something in my ears also triggers headaches, and obviously can’t wear plugs at work where my job is to listen and sing along.
It’s also just annoying to have everything December be Christmas - and I say that as a secular Christmas celebrator. There’s so much more to celebrate this time of year, but you’d never get a chance to know it.
I think a lot of people who celebrate Christmas have noticed it becoming even more overcommercialised than ever before, but it’s not really, it’s just a new type of commercialisation with so many industries being “fast”. Those on the outside of Christmas (Jews, Muslims, Pagans, basically every other religion and spirituality outside Christianity) the overcommercialisation has been obvious since the Victorian era.
I made a new comment for your edit cause I didn’t mean to ratio, just trying for discussion. It’s not a big deal to dislike it; I guess I just think of it as winter holiday season and not Christmas season. And I’m guessing it’s not a bunch of triggered Christians downvoting it’s just people responding to what comes across as a little grumpy (which again for the record is an opinion you’re entitled to).
I think overtly religious displays and sanctimony are pretty annoying. I just don’t see the rest of the season as affected by that. Maybe they’re Chanukah lights. But to steel man you a little: if anything I’m more triggered by the consumerism and capitalist co-opting of time to reflect and be with family than any religion being overbearing, which goes along with what you’re saying regarding the overboardness people do with the decorations and extraness of their lawn displays and the presents and holiday sales etc.
I’m in a similar boat, but I appreciate anyone trying to make pretty public displays. I might not agree on the definition of pretty, but they’re trying, and that’s pretty great.
IMHO restraint is key with light displays. Make it lightweight and pretty, think minimalist and I am on board. Big plastic snowmen and Santas can fuck right off.
Generally speaking, yes. But if someone goes through the effort to put that crap up, good on them.
I live in an area where people put up pretty terrible looking homemade displays. If they went through the trouble to make it, I’m going to find something to appreciate.
Unless I’m gravely mistaken, I think Christmas and the winter holiday it’s centered on is actually pagan and has been celebrated for a staggering length of time. The whole tree thing and yule log and all that. I think religions just kinda co-opted it since it was already being celebrated and nobody was quite sure when Jesus was born exactly. I’ve noticed that a lot of Irish music and ancient tunes were later transferred into church music with some tweaked lyrics too. But the underlying music can be quite a bit older.
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.
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!”
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.
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.
Even a 2kHz rate can be a problem when the implementation is cheap and you get weird harmonics that distort the PWM and might create lower frequency flicker. I’m thinking interactions between cheap power supply voltage/current ripple and LED PWM. I personally don’t know enough about this kind of LED implementation to say what could or couldn’t be happening.
