Thread 106142633

You're not one of those weirdos who uses 3000k+ hospital lights in your own home, right /g/?

what does it matter when it's all fake LED trash anyway

real light is only produced from heat

to have light without heat is unnatural and satanic

2700k here

2000-2200k is too yellow for my tastes

>>106142633 (OP)
2000, 2700, 6500, 8000

>>106142659
ok luddite. i guess you'll go back to using oil lanterns and candles.

>>106142779
unironically based

2000k in bedroom, 2200k in living room, 2700k in kitchen.
Luv me amber glow, simple as, only place I'd ever use above 3000k is work areas like the basement and garage.

>t. Prime Rib at Ponderosa Restaurant

I replaced all of them in my house with 3000k bulbs, peak comfy
Had to pay out of pocket for some for my office room because the company didn't want to buy them and when I replaced them there everyone decided they wanted the same so they bought 3000k light bulbs for everyone and now I feel like a retarded mongoloid

>>106142874
This is actually pretty comfy. Your eyes don't need to adapt to red light in the dark, so this is the most optimal when you wake up during the night, for bathrooms, etc.

For the dimmable in my dining room, I use Philips Warm Glow. 2200K at low intensity, 2700K at full intensity.

Incandescent for bedside and desk lamps. Dimmable 3k for everything else.

I've been in my flat 3 years and the light bulb is still working. Don't know what it is.

This talking point parroted by this human trash is an ongoing campaign to get people to waste electricity.

I have Zigbee lights that I control the hue with one of these cubes and also have automations to change depending on the time of day. You should adapt your surroundings to what you see fit for the task.

I prefer my room to have around 300K myself

Legitimately don't understand how anyone can stand having lights above 3000k, that shit would drive me nuts, the moment I realized 2000k bulbs were a thing I already started considering 2700k sterile work light.

>>106144503

2700k for the bedroom.
6500k for the bathroom.

like i understood the excitement over blue led's, they really stood out in the '90s because we were so used to anything but blue, but they seem to have forgotten why they used blue leds in the first place and now they're just everywhere like there aren't any other colours.

It made me mad that I lived in the northern hemisphere. We sailed from Hawaii to the Persian Gulf, then to southern Australia & back to Hawaii. It was almost surreal how prominent it was in the sky and I have never seen a photograph that had captured it like I saw it. The light pollution even in the desert south of the Grand Canyon doesn't allow you to see the sky like you can in the middle of the Pacific Ocean. I have circumnavigated the Earth twice, and have never seen such a sight other than those few nights at sea. I am on the verge of tears right now. Such wonder and magic. Holy shit.

>>106142633 (OP)
What I noticed lately - browns - turks, syrians etc are using cold lights, where whites are usually sticking to warm lights. So you can even tell, which homes exactly do brownies live in.

>>106148487
i haven't considered if there's a cultural aspect to this. i've been doing some electrical work for a pakistani guy recently and i find it odd how he insists on every light everywhere being 6500K. personally i'd only use 6500K in a kitchen or bathroom

>>106143223
Unironically, LED causes schizo. Vicious feedback loop.

>>106144610

No, you're a failure in nature and evolution.

>>106143174
Your eyes actually need red light for your brain to fine tune your focus

>>106148487
>>106148521
It's because they live it hot climates where the nights are still warm, so colder lighting makes them feel cooler
Whereas in the Northern climates the nights are cold so you want a nice warm cozy light that's like being near a fire

Also the whole "incandescents are inefficient" is bs in practice, because in summer I'm not using them, but in winter it's cold and the heat generated is useful and means I don't need my fire/central heating on as much, so it's not wasted

>>106148521
>>106148487

I wonder if eye color has anything to do with it. Maybe light eyes are more sensitive to bright cold lighting.

>>106142633 (OP)
for me, it's 2700-4000K, depending on context.

>>106149436
They are, brown eyes are brown because they have melanin in both the iris and pupil, which helps see clearly in the blazing bright sun of equitable regions
Whereas light eyes see better in low light and the dark

>>106149470
I have blue eyes.
I still enjoy 4000k/5000k lighting.
Of course its hard to say if my preference isn't colored from other eye problems.

LED is better for outdoors, incandescent is better for indoors

>>106149792
leds for example produce light via electroluminescence, the light they produce is no different to light produces via incandescence outside of the spectra they typically produce. like if you isolate a particular frequency of light between both sources, they're the same thing, there's nothing inherently different about the light an led produces versus the same frequency emitted from an incandescent source like a flame.
there are many species of fauna and flora that produce light via bioluminescence or phosphorescence rather than incandescence

>>106149797
for high pedestrian areas it is okay.
notice how there are darkspots.

>>106149927
This is the problem with bright white lights outside in the dark, your eyes will adjust (after being dazzled) making it harder to see the dark areas between lights
Sodium lamps have less impact on your night vision making it easier to see on the dark areas

The very first recorded light in Scripture — Genesis 1:3:

> "And God said, Let there be light: and there was light."


That light preceded the sun, moon, and stars (created on Day 4).
That was light without a thermal source — by divine command, not combustion.

This affirms your intuition in reverse: not that heat produces true light, but that light itself is more fundamental than heat. Light came first.

Sometimes I wonder if the reason why some people don't like the left is because shit looks too stark orange and doesn't have a wider spectrum kind of like actual sunrises/sunsets, or maybe I'm just a brainlet (probably)

LEDs produce SHIT light. They're only good for indicator lights on electronics and having them replace actual lighting is pushed by the Anti-christ. It's their fault there's no innovation in better lighting technology.

>>106151534

>>106151556
low pressure sodium street lamps aren't just low temperature, they're literally monochromatic. like the emit an extremely narrow yellow light and nothing else. it's nothing like firelight
one of the biggest arguments against it for street lighting is that it provides absolutely no colour differentiation, everything literally looks the same

>>106151631
Wait until the greens start seething and make the government pass a law so it's illegal to sell clear colored incandescent bulbs and you must color them red or something

Between 2700 and 6000. I live in the Arctic and it's either permanently dark or bright for like 8 months of the year, so I've gotten smart lamps with adjustable color temp and I've written a simple program that controls their color temp based on the time of day. Crank it all the way up during the day and bring it down from evenings to mornings. Helps keep my body in even some sort of rhytm and the bright lights during the daytime help against SAD.

>>106151556
>shit looks too stark orange and doesn't have a wider spectrum kind of like actual sunrises/sunsets
It's that, yeah - an actual sunset still has a pretty broad spectrum of colors, reds, oranges, yellows, greens, etc., it's just much more weighted towards the warmer side, but you can still clearly make out different tones with ease. Meanwhile, if you have a light source that's just literally pure orange, it immediately sets off a sort of uncanny valley. because everything looks distinctly "off" even though it's trying to replicate sunset.

>>106142633 (OP)

For kitchen you want 4000k or 4500k. Supposedly 5000k is closest to daylight but I don't think this s right. Anything below 4000k and the food does not look right if you are picky about how much the meat is cooked. 2700k is too warm and looks like fake incandescent light kind of uncanny valley. I use osram glow frost 3000k for all room except philips 4000k for the kitchen.

>>106153357
Back in the day you would have a photodiode or some other photodetector that was relatively linear in output no matter the wavelength. You would then use color filters which block out everything but a specific wavelength.
It's then as simple as putting a color filter over the photodoide and measuring the output. With enough filters you can get a chart of wavelengths and their relative intensities.
This is 80s tech and would be automated of course.

More modern solution is to use a prism to split the light and the split light lands on a strip of CCD sensors/pixels.
This can also be done with just a regular camera and a prism but not as accurate or as detailed of a spectro graph because of the bayer filter that's programmed in hardware

>>106152842
Some fixtures are more insulating than others.
Some fixtures literally have insulation on the tops of them because it's possible to stick 200W of incandescent which will gladly incinerate things.

I remember when I was looking at some eastern european dude's website trying to buy a high CRI bulb (it's pretty obvious he's mainly serving the weed grower market).

>>106151556
I prefer right because it shows more colors than left. Also Sepia is culturaly associated to me as a period I don't really like. I also have bad memory of visiting homes for dinners in atmospheres I did not like, and they used low K tones back in the days. Also low light is typically associated to me as the end of the day, which is pretty melancholic to me. I prefer 2pm light and moonlight.

>>106148436
Electroluminescent blue was a thing, though. Shame that they couldn't copy that shade to mainstream blue leds, it was much more eye friendly.

>>106160622
true, but EL displays weren't really used for point lights that i've seen, and it's very obviously cyan rather than the eye-raping blue that GaN blue led's are

>>106160622
>Shame that they couldn't copy that shade to mainstream blue leds
also worth noting that due to how LEDs work, you can't really just pick any arbitrary colour. there's a reason why LEDs are red, green, amber, blue, and basically nothing else. even white leds are just blue led's with a phosphor coating that converts some of the blue into a wider spectrum.
in fact, cyan is something that led's struggle with specifically. look at any white led spectrum and you'll notice there's always a dip around cyan

Absolute wrong way to go about it.
High CRI is useless for that application.

2700K is the max I ever go. I didn't realize how autistic I was about color temperature until I started seeing disgusting 3000K+ LED bulbs everywhere. It's fine in offices, workshops, doctors, etc but there are real negative physiological and psychological implications to having blue light blasted into your eyes in home environments. I don't know how the mongoloids who willingly put these in their homes put up with it. Also 90% of the time it's a poor/nig/spic/jee/chinkt/bug that's doing it. And don't get me started on the tacky ass over 9000K LED strip lighting they use in their shops.

>>106157301
Ra is indeed way more important than most people would think. I measure lights almost daily in integrating sphere and the first time I saw a powerful 6500k high CRI light I literally went "wow, this looks just like sunlight!". That has never been the case with any other cool white lamp, since they're actually just mostly blue and skintones look awful with those.

I exclusively use incandescents

i use 2000k most of the time when my curtains are closed, but when i have natural light coming through in the morning i change it to 6000k.

how is color associated with temperature anyway? is it because emitted light's wavelength and total energy are interconnected with the object heating up?

>>106169003
You heat up something enough, it starts to glow
The color of light you get a certain temp is the color temperature.

>>106151635

Speaking of which, who's exactly in charge of street lighting in any given area? The mayor of the city/town?

Which tent is better?

>>106169254
well yeah, but a side effect of that is the object starts emitting radiation, first as infrared (it's why you can see things on a thermal cam) then as visible as it gets hotter.

Get an ideal black body, heat it up to 2000 kelvin and the light it emits is 2000k light, the relationship is direct.

>>106169332
does that mean it's possible to make something so cold it becomes perfectly black? as in no radiation is reflected? or is that the ideal black body in the first place?

>>106169309

Goddamnit why does this country have to be so arbitrary

>>106169370
>or is that the ideal black body in the first place?
An ideal black body reflects nothing, only emits radiation
An ideal black body should emit no radiation at absolute zero, at least it shouldn't but you getting into weird quantum shit and it's impossible to create both an ideal black body and reach zero energy.

>>106169533
that sounds like a black hole but that's obviously not zero energy since it has mass and releases hawking radiation.

>>106167282
CRI over 90 is no longer a helpful metric. Lots of shitty companies like Phillips and Feit do this orange spike thing to juice their numbers. You have to actually look at a spectrograph or qualify CRI with R9 >90 to see a real improvement over generic 90 CRI bulbs.

>>106169636
I mean I figured they're all cheating or even straight lying in the case of chinkshit anyway. But there's no practical way for me to verify it, even an opple light master would be difficult to justify for one-off use.

>>106169685
Yeah just buy incandescent if you care about color. It's not that expensive.

>>106169636
So is it actually difficult making bulbs and/or LEDs that actually have more natural spectrums, or is it actually easier than you'd think but they just don't care to put the effort?

>>106169746
I'd need like a massive 80W bulb to match a tiny 12W LED in brightness.
That's almost 3kW to light an entire apartment.

>>106169798
It would be like 1.3kW if I did every fixture in my 1200sqft apartment with incandescent and turned them on full intensity. You don't need to match brightness with perfect color either.

>>106169750
It's not hard to have better color if you add a 2nd or 3rd LED color. It's probably not hard to just use better phosfors either, but why give those away when film will pay a 100x premium?

The business I work for bulk purchased a bunch of direct-wire LED 4ft bulbs to replace the aging florescent bulbs we have installed around the campus. I am in charge of facilities so I replace the bulbs a lot of the time and I have swapped out the bulbs in probably 80% of the buildings now. These bulbs are the type that have a switch that changes the light color temp and I always max them out, which on the bulbs we have is 6500k. People hate it but most don't realize there is anything that can be done about it.
In the building where I have my desk and computer all the bulbs are set to the warmest setting.

As expected of /g/.

Colour temperature doesn't matter as much as a uniform spectrum. Even if a combination of peaks may add up to the rough impression of natural light, those missing frequencies still aren't being reflected off food, making it look rancid. Using food as an example because it ties into survival, pleasure and "what's natural", and restaurants seem to neglect this matter. Granted also, this was a much bigger issue 15 years ago than it is now, but I still find it weird to reach for a bedside lamp switch and not feel any heat emanating from it.

>>106169003
it's based on ideal black body radiation. that is, an ideal black body heated to 2,000 Kelvin emits "2000K temperature" light. this of course doesn't mean something has to be 2,000K to emit those wavelengths, in typical non-incandescent use it's only an equivalent value

>>106142633 (OP)

>Using food as an example because it ties into survival
You're using food as an example because it's one of the few areas where a "uniform spectrum" might be considered important, while implying that it is important in general.

bulbs are still pretty useful because you can swap them out easily, they do go bad after a while or you might change your mind on color temperature or luminosity

What are the cons of getting an infrared bulb like the chicken coop ones, and using it at my desk? My home office is in the basement and it gets chilly during winter. An infrared bulb would use less power than an electric stove

>>106173728
main cons i can think of are that you can't have heat without the light and that you need it to be directed at whatever you're trying to warm up, which might limit feasible placements. of course you'd need a special fitting for it as well so you don't burn your house down. combined with a dimmer it would be a pretty comfy setup.

You'd be surprised how proper lighting lets you see better and distinguish colors more accurately.
I love warm yellow lights for the look, but I need to see properly more often.

>>106165553
well "colour temperature" as commonly defined relates to visible light (as visible to humans), so you'd have to look up the lowest frequency of light a human can typical see (some kind of near-infra-red) and what temperature a black body would need to be at to emit such radiation.
once you have that, that is the "lowest colour temperature possible"

>>106174309
Not really. Warm LEDs have worse subjective color because their output is so heavily weighted toward orange. If you compare tungsten vs halogen vs xenon, it's going to be very similar.
