thank you LEDs
How do you make light from salt
>>107079057you set the light on fire
>>107079041Still can't see the stars. Wtf does it matter?
Aside from the color temperature change, this map really just shows light pollution, which is orthogonal to the technology used to create the light.
Here we go with the fucking esoteric horseshit again.
>>107079110>Indigenous New years is based on a constellation>city has a festival for Indigenous new years>cannot see the stars in the city
>>107079041>welcome home>KILL YOURSELF
>>107079456I'd be mad if I were "welcomed home" by 1900K.
Who cares? It's much cheaper now
>>107079129Most complaints about LEDs are mainly about the color temperature because many places default to using cold white ones instead of warm white.
>>107079161Now we have calendars so we know when the stars will come out even if we can't see them.
>>107079565>many places default to using cold white ones instead of warm white.No they don't.Cold white LED's are hardly ever used even in places where they should.Just because it's not piss yellow doesn't mean it's cold white.
>>107079124The ground also reflects light back up.So every street light causes light pollution.
>>107079041>OP doesn't know how shit works and doesn't realise that the right image is actually brighter.Almost 2026 is OP is still a faggot.
>>107079041I hate the white light of LEDs. I've basically stopped driving at night now because of the blinding white lights, from both street lights and cars.
>>107079041I thank LEDs every morning when I wake up, and every night before I go to sleep.
>>107079568Just seems ironic. Like the mining company that just burned a Forrest having a lorax party.

>>107079041so all those sci fi movies that show a bunch of lights all the way from space were right
Kill yourself OP. Everybody knows you can just filter out sodium lamp. Can't filter LSHITTINGD
Why don't they just make the led streetlights in warm colors? I can hear those cold lights whispering to my ear to kill myself
>>107081692Because "LE SCIENCE xD" says that cold light provides marginally better visibility at night than warm light so we have to live in the ugliest possible world forever now.
>>107081692Mostly it's a cost and power efficiency thing. They are sold as being cheaper and more environmentally conscious. In the US a lot of them are supplied by a few companies that stepped up to meet the in my mind probably unrealistically low cost target set forth. The only way to balance the cost and light output was the current led plate arrangements we have now. The problem is the phosphor coatings are cheap, deteriorated faster than people expected, and as they age they get bluer and bluer to the point many end up shifting to nearly purple light. Most of the ones they installed where I live started to fail in only 5-7 years. They started out more like a 4500k headlight bulk in colour, but as they age they end up more like 6500-7500k, with fully failed units being nearly purple or lavender.To get those yellow and warm white hues you often drop the efficiency of the led as it has to fight through more and thicker coatings to not be the harsh white we associate with led.
>>107081717Are you wearing orange tinted contacts? Wouldn't it make daylight so much better according to you.
>>107081810daylight fucking sucks

>>107082355neat wallpaper
>>107081717>cold light provides marginally better visibility at night than warm lightToo bad it fucking blinds you to anything outside of the illuminated area and makes it so you can't see shit through a denser atmosphere
>>107079057Make em lose enough games and they become incandescent with rage
>>107081788>5-7 yearsThat is pretty much the same lifespan as a modern low-pressure sodium vapor lamp, so LEDs are really only better in terms of spectrum and efficiency (they're roughly 70% more efficient than sodium vapor apparently). But clearly if they're shifting into violet over time, their spectrum is actually a lot narrower than advertized, and probably only win out in terms of efficiency after a few years. Still more economical than sodium vapor, but in terms of quality of light and lifespan the imrovements are only marginal.
>>107082447>Too bad it fucking blinds you to anything outside of the illuminated area This is something I noticed when they replaced all the lights in our city, the area directly lit is fine, but everything beyond that is pitch fucking black, and in heavy rain and snow visibility is almost zero even directly under the light. Never had this problem with sodium vapor.
>>107082417Save it, it's all yours my friend.
>>107080933Literally none. There's no way on a grid scale to save power. It's all generated just-in-time and equal to demand on a moment to moment basis. You turn on your microwave for some tendies and a power plant somewhere has to start immediately generating an extra 1000 watts for that 3 minutes. If they make too much things get damaged and if they don't make enough the grid goes down.Also AI data centers use more power per center than every sodium streetlight in the country ever did. Just give Sam Altman 500 billion more megawatts and he will solve AGI
>>107080933Literally zero.
>>107081788Where I live they replaced the sodium lights with 5000k leds and it went from "road and sidewalk illuminated, yards dark" to "yard lit up enough I could mow at midnight, and if the front drapes are open I could read a book from the light spill"I swear they went with the same wattage lamps despite led putting out more candela/watt
>>107079041Sodium lights were so weird, I always wondered why the fuck the sky looked pink at night sometimes when I was a kid.
>>107079041sovl vs sovless
>>107082720They emit monochromatic light, the spectrum on them is so narrow that color differentiation is impossible underneath them. It isn't just "more warm", everything they illuminate is literally pure orange. That is the wierdest thing about them, you can't replicate it with mere "warm light", we're never going to see it ever again because even warm LEDs have a much broader spectrum than sodium vapor.
>>107079041Thankfully I live in a nice area where they cared enough to maintain the yellow. LED doesn't mean it has to be deathglare blinding.
>>107082515I think when they were first pushed out they had a 10-15 year touted service life in theory, but in real world conditions they just do not seem to last as long. They can also be combined with smart lamps that automatically dim or cut off, where as many arc lamps take significant time to reach usable brightness levels making them impractical for these "on demand" uses.I also assume that because of the supposed longer life, there was a support force reduction for upkeep, at least here which also makes them cheaper on paper. Where an old sodium lamp would be replaced in a day or two after it burns out, the LED units will be purple for months, or even totally fail and take weeks to get replaced.
>>107082515> 70% more efficientUtter lies, in reality they save energy by outputting no light. The old street lights lit up everywhere, modern leds create a sad puddle of light directly below the lamp, and utter pitch black everywhere else. They are so useless their utility is actually negative. It would be an upgrade to get rid of them completely.
>>107080933Even if it saved some energy they'd just add more consumption to meet supply. This is the scam of all "resource saving" technology, more efficient consumption just makes it easier to consume more. You can't reduce consumption by building more new stuff.https://en.wikipedia.org/wiki/Jevons_paradox
>>107082896Thr problem you have with LEDs is that based on the temps everything runs at and expected lumen degradation, there is no reason they shouldn't last 10-15 years.It only takes one fuck up, in one manufacturing process of one component to take that lifespan from 15 years to months howeverThis wouldn't be an issue if things where standardized but anything regarding LEDs is not. Sodium lamps and every support component where all manufactured based on ANSI standards so it was piss easy to replace a bulb, ballast or starter from another manufacturer.
>>107080947>>107082658wrong, it saves a lot, deal with it faggot, LED Chuds WON

>>107080933>savedLol no LEDs are so fucking cheap to produce and run that they're far more numerous than old lighting tech ever was. This is why light pollution is also far worse with LEDs, there's just a lot more of them now.
>>107082675I'm grateful that the ones my municipality have installed are not that disruptive. They're more like 3000k, and brighter than the old sodium lamps, but not excessively. Probably the only good decision our city council has made in decades.
>>107083873>This is why light pollution is also far worse with LEDs, there's just a lot more of them now.I have noticed that businesses don't even bother turning their lights off at night anymore because the running cost of LED is so low. Didn't used to be the case with fluorescents, neon, etc...

>>107084878you replace a 70W HPS with a 40W LED because it gives superior visibility despite less lumens
you fucking brainless homosexual niggers are the reason why I cant see SHIT at night anymore, since congress by law made all vehicle headlights white LEDs in 2021,And I'm supposed to believe street lights mattered or made anything better when I see, directly into my optic nerve, what white-to-whiteblue LEDs do to people?No fuck off, retard.
>>107084958this has never happened
>>107084958no it doesn't, you mean more lumen per watt.
>>107084982no. if you equalize for visibility, the led uses less lumens.
>>107084893That stroad is soulless under any lighting condition,
>>107085012no, it doesn't
>>107085034Not him but I think what he's trying so say is IN LOW LIGHT CONDITIONS the human eye is more sensitive to green and blue light than to red and yellow light.This makes yellow street lighting quite inefficient in the real world even when the lumens per watt seem good on paper.This is also why blue status LED's are so annoying at night: they look far brighter than red status LED's at night even if they look similarly bright under daylight lighting.
Don't let yourself be gaslit by LED propaganda. LED is just BAD light. It's unnatural, has poor light quality, and is Satanic.

>>107084798>newYou must be young. And the people that complain most about light pollution are the rural right, as their small towns get bigger and they can no longer see the stars.Light pollution is trash.

You'd think by now it would have been figured out some scientifically optimal night lighting that is tuned for specific human vision needs, but no we get monochrome lamp flame orange or the world's shittiest LEDs. God forbid they decide replicating sunlight is ideal. Good luck staying sane when your body is always getting the signal that it's high noon at 9pm.Uncle Ted was right, technology is a mistake without severe control over its proliferation.
>>107079041I hate LEDs on streetlights but I absolutely fucking seethe at LEDs on cars
>>107084769>>107084783>>107084792>>107084800Honestly, I prefer when the light is "color coded" for night.Yeah, you see better, and colors are more accurate with led.But night shouldn't be for activities anyway, so a warm light is preferable.It also intuitively codes for "warm light" equals "night and inaction".But, yeah, I don't have my saying in it anyway...

>>107079057salt + water = saltwater which is an electrolyte which can be used to conduct electricity to complete an electric circuit which can include a light such as a sodium lamp
>>107087467For me it's the flickering. I can sense the, I guess PWM, whatever, of the LEDs and it's distracting.
>>107087377>t. is a 4chan meme
>>107087507I think that's on purpose and is achieved by refraction in the headlight "lens" -- headlights run on steady dc, it is literally just a light. but there's wacky fresnel lenses in the covers to make them reflective and appear to "glow" even when the lights are off but they are illuminated by others' lights.

>>107088177czeched
>>107081717actually cold light just prevents you from sleeping. its "safer" cuz it prevents people from dozing off while driving. to actually improve visibility we would use selective yellow (basically full spectrum white light minus blue). not to be confused with narrow spectrum yellow like sodium or yellow LEDs

>>107084693>LEDs produce a cleaner light which makes objects more visible (important for things like driving)define "cleaner". white leds have a wider colour spectrum than HPS, which makes objects easier to differentiate>LEDs produce a cleaner light which allows you to use less energy for the same visibilitythey're more efficient than HPS (given high quality samples of each), but again what does "cleaner" even mean here?>LEDs produce light that is more even over its range while HPS will have a bright spot that degrades rapidly (see >>107082355)>LEDs produce a consistent light over their lifespan whereas HPS degrade these are both basically the same points. LEDs also degrade in brightness over time, i don't know how they compare with HPS specifically in this regard. it also depends greatly on how they're driven, well-made lamps with diodes driven at low current will be both much more efficient and last much longer (so of course shit consumer bulbs drive them as hard as they can)>LEDs turn on instantly whereas HPS require time to warm upthis one is true
Just replace the shitty "white" (blue+phosphor) LEDs with monochromatic yellow/amber LEDs.>nostalgiafags are happy because it looks just like LPS>wildlife is happy because they aren't bombarded with blue light anymore>astronomers are happy because they can just filter out the right wavelength and get rid of street lights >towns are happy because the power bill is basically the same as with white LEDs and they can be retrofitted onto existing LED infrastructure

Another post by the schizo who is obsessed with inferior and inefficient technologies.
>>107079124A LED can have good optics close to the LED, with a lens array. A sodium discharge lamp refractor needs to be far away from the lamp and even then it won't be directed very well. They let it spray around, rather than shield it and turn it into heat.
>>107082355i honestly believe they did it on purpose to predictively program us to see less beauty in the world.
>>107085492are you saying that LED made people buy huge SUVs and smoke meth behind the wheel?
>>107091106Narrowband amber LEDs are not (yet) efficient or reliable. Also, not everyone likes amber light, let alone monochromatic amber light.
>>107091191>not everyone likes amber lightwe should offer to them the same amount of sympathy they've offered to amber light enjoyers: none
>>107081717which is immediately negated when someone coming the other way blinds you with their LED headlights that shine with the brightness of a thousand suns even on low beam
>>107091317i was just adding context, because original post made it sound like amber light is universally loved, which is simply not the case. shit sucks, but what can you do... other than move somewhere where they have strict regulations over blue light or somewhere where they don't have any lights.
>>107088159kek, you just applied a grey filter.Look at the sky, the yellow image was cooked.Try to apply a white balance calibration between the left image and the yellow part in the right one, then you can more or less compare.Also, remember to use hue and not grayscale. We humans see green better, and classic grayscale don't take that in acount.But anyway, I think what people who love led want to push is whiter light.I disagree (see >>107087335 ) but I think that's what they like about it.And, yes, it's brighter. And not only because it has green in the spectrum that we human see better.
>>107079041FUCK Lemurs
LEDs are based. have had a night light plugged in near my bathroom and it's been running 24/7 for like 4-5 years now.LED headlights in cars are too bright though. they need to regulate that
>>107091643>LED headlights in cars are too bright though. they need to regulate thatThe brightness isn't the issue. The angle of the light is. If you're in a sedan then you will be blinded by every truck or SUV because their lights are higher and the angle is projected in a way that blinds anything lower than them. The USA has some of the worst regulations on headlights btw. Europe and many other countries already solved this issue years ago with AFS but the USA has, for many years, refused to regulate manufacturers to use AFS. Even still they can't get their shit together to regulate it.
>>107084446I'm a 0 Kelvin man
>>107091903Cars are already goddamn expensive enough.Already we have gone from $20 sealed beams to $1k+ assembles
>>107091566stop raping my night sight
>>107085615That's actually CAFE regulations, and giant vehicles peaked before the Obama administration. The current trend is only attributable to shitlibs importing niggers by the millions and giving them drivers license with no exam.
>>107091903AFS can't fix semis. The real solution is to abolish CAFE and let tradies have cheap trucks again, abolish belt height regulations, then add license requirements to SUVs so you don't have so many fucking retards operating jacked up vehicles.
>>107091903It's not just the angle, but also the density. They put these stupid RGB cyberpunk headlights where the entire headlight is just one thin line, making it 100x brighter since the light shines through that much less area. It fucking blinds me even when I'm on the sidewalk.and yeah not being able to just change the fucking bulb inside but instead you have to replace a $1k+ assembly is just bullshit.
>use 2200k LED's to get the best of both worlds
>>107094930Actually less efficient than low pressure sodium. LED is catnip for midwits.

I personally use red party lights in my room because it reminds me of the womb and warmth and ... blood, gore, etc.And that makes it FUN.
>>107086556>distracted driving is a compounding factorLook at 2010 dickhead.We all had smartphones in 2010 dickhead.Nothings changed there.LEDs literally fucking hurt my eyes on the road. I haven't been able to sleep properly for years thanks to them either.

>>107091566You're not meant to compare the left to right images in the greyscale example. It's showing that the yellow light in the right image is actually brighter than the white light in the right image.
>>107079124LED blue peaks are bad for light pollution.Red light is barely visible as atmospheric scattering.
>4000K LEDs are only 10% more efficient that LPSI expected it to be more.

>ahhhhhhhh save me niggerman, i cant see, this NEEDS to be blindingly bright whiteyour eyes work better at night under dim, heavy contrasting lighting which HPS is literally perfect for. Between streetlights and headlights LEDs fucking rape your nightvision and make night driving signifigantly more dangerous than it needs to be. There are places where i live that are absolutely miserable to drive because the streetlights only really illuminate whats underneath them and you cant see behind them at all. Just because shits getting brighter doesnt mean you can actually see better.
just drive slower silly
>>107097466>Between streetlights and headlights LEDs fucking rape your nightvision and make night driving signifigantly more dangerous than it needs to beToo fucking true, its so fucking irritating anymore
>>107097659>sorry about that .01 degree grade vroat this point, magdumping into the windshield of these cars should be considered self defense because on tight, twisting roads i have to come to a full and complete stop to avoid the risk of dumping my car in a ditch because i literally cannot see beyond the headlights. If we magically went back to HPS/incandescent headlights people would realize that none if this shit is even close to necessary and is all just part of a slowly escalating pissing match>everyones lights are so bright that i cant see>so i will also get brighter lights>everyones lights are so bright that i cant see>so i will also get brighter lights>everyones lights are so bright that i cant see>so i will also get brighter lightsand so on.
>>107091334you'd think by now there'd be some kind of filter you could put on your windshield that reduced headlight glare, because jesus fucking christ having to drive down a road with your hand blocking 70% of the road because of the sun driving towards you at eye level is fucking terrible.

>>107094930They mostly haven't gotten around to getting rid of HPS in and around Barcelona. Now they're in a better position to adopt warm LEDs, since they're more feasible.Brazil actually put out a regulation that limits new streetlights to 2200K. Hope the rest of the world follows.>>107095128There's not many light sources more efficient than low pressure sodium, especially at high outputs.
soul -> soulless

>>107089755Bring back the piss filter for real life at night.
Even the LED taillights are too obnoxiously bright. The taco bell employees probably think I'm a pothead because whenever I'm making a nighttime taco run, if I end up behind something with LED taillights I have to put my sunglasses on because they are so damn bright!>>107090818Ssssiiiiggggghhhhh...... Should've known....>>107098009Some of them are so bright that my eyes do that reflex where they close, like, you know when you're trying to get your photo taken but the camera flash keeps making you blink?It's like that.

>>107095702You have schizophrenia. Your sleep has not been impacted by LEDs.Please see a doctor.
LED light is repulsive not because of the color temperature but because of its low fidelity recreation of the spectrumLED light makes you sick just looking at it for reasons you're not even aware of
>>107100415This poster thinks white light from an incandescent and "white" light from an LED are exactly the same because they look the same on a white wall.
>>107100668You think everything is causing you pain. You think it’s a giant global conspiracy to specifically injure and frustrate you.You are schizophrenic.
Both hurt my eyes.
>>107100746>proves his ignoranceYou don't even understand how electromagnetic radiation works.
>>107100746not everything that's harmful is deliberate. nobody is calling it "a giant global conspiracy to specifically injure and frustrate", that's entirely your own assumption.
>>107095702you are retardedthat is all
>>107100819The same schizo makes anti-LED threads every day on /g/ for years. I know who it is. He needs help.
>>107100746That's not what schizophrenia is, retard.
>>107101501>Why "beaming pain" can be a symptomA person with schizophrenia may describe a symptom as "beaming" pain due to the nature of the experience and their way of expressing it. This is consistent with how other sensory and psychological symptoms are expressed.The feeling of pain can be connected to the sensation of feeling controlled by external forces, which is a common symptom of schizophrenia
>>107084709It something completely irrelevant unless you're running a telescope, hence they are usually built away from cities so they don't get affected. Bonus info: same thing for radio telescopes with radio interference.

>>107101851>one of the primary claimed benefits of LED streetlights is that it helps drivers from falling asleep at the wheelI have literally never seen anybody say this lolmeds now
>>107101851I haven’t heard that claim but even if that were true, you don’t sleep outside under LED street lights.
Look at a sodium lamp, look at a 4000k LED lamp, feel which one hurts your eye the most.LEDs suck and take away your vision.Turning night into day is a form of trans-night
Clean your windshield, but yes, the peaky garbage lowest bidder street lamps are a problem. There should be standards for road-use lighting including >intensity of the perceived source to promote diffusion and reduce glare. You can achieve the same light output from more of a less intense source>measured spectrumto make sure your rods don't get blown out by higher energy light reducing their sensitivity>beam patternso a lamp post a mile away doesn't glare >actual brightnessto lessen glare when it's wet outside
>>107083018It is not in the energy company's interest to save energy. In the end you will be paying more and consuming less.
>>107102384A lot of municipalities will actually pay the local power utility to operate the lights for them, including replacement as needed. In that case, the power company has a huge interest in keeping usage low to maximize their own profit
>>107095619Yours goes from this #0B1A30 to this #3D4752 after the lLED.

>>107079057wait until you hear about how humanity tricked rocks into thinking
>>107099918all false
>>107102715The yellow light is flat as well. The lights just appear to get less flat as they get further away from the viewer. Look at the foreground in the left image. It's basically just as flat as the right.
