cooler light is more popular in places where it gets hot: Middle East, South East Asia countries prefer using cooler tones because it gives feeling of freshness and cooleness

I love my daylight bulbs
3500 to 5k. My brain hates all others.
Feel like youre playing both sides
3500k is warm 5000k is daylight
Nobody is buying higher K for their home
Am I the only one who doesn’t replace light bulbs based on color temperature? I usually keep around whatever is already in the rental unit/whatever spares the last tenants left around, because I usually move every year anyway.
In the rare chance I get a choice, I usually choose daylight though.
Most people I know who do care.
Change all of the bulbs when they move in. Throw the old bulbs in a box.
Put the old bulbs back when you move out.
Use the new bulbs at the next apartment.
Some of them also have smart bulbs and those are way too expensive to give away.
I definitely have four different temperatures in my tiny studio. I imagine that would set a sort of person on edge.
I don't go out of my way to replace light bulbs with all these smartbulbs that have day/night cycles.
That being said, if they go out, I normally pick a smartbulb because the price difference isn't that much for all it offers in return.
I've been working remotely from 3 to 10 PM and the gradual change in color temperature both from the smartbulb and my screen really helps me take it easy as my shift is ending.
Modern society is telling me I need to take melatonin.
I tell modern society I make my own melatonin, and sleep perfectly fine because my lights are warm in the evening.
WoHo, míster not addicted to your phone who doesn't watch it in bed.
We can't all be like you.
Jokes aside, swtiching to a eink reader helped my sleep so much it's not funny
I can't help you with your addiction, I can only offer warm glow.
We don't know Celsius. How do you expect us to know Kelvin?
10800 to 18000°Ra for the Americans
Oh, thanks! That's... totally a comprehensible metric for humans that have been inside several suns.
My sisters can't decide which ones she wants to use, so every room has a different lighting hue. Most rooms have different bulbs for each lamp, so hot and cold are right next to eachothert
I have a somewhat basic home automation, and my lights are programmed to be cooler during daylight hours (where necessary, desk lamp, corridor, etc), and they become warmer at night. The reverse happens early morning in winter, where I wake up while still dark.
Daylight is full-spectrum, not just cool. Flicker-free and high color rendering index. If you can get that in a bulb (bit more expensive than cheap LEDs) it's quite nice indoors.
Daylight spectrum is skewed by time of day from blue shifted to red shifted.
True, but I just mean that daylight has properties that not all LEDs do, which is why some LEDs may seem harsh even if they are the same color temperature as daylight. But a good LED with high CRI and no flicker is nice at various temps.
There's a solution here you're not seeing... RGB lights. Setting the hue on the fly to match what I need has been pretty neat. Pure white for work, natural white for relaxing, red only for venting in the summer since insects can't see it, green and blue strobe for dance nights, the only limit is your imagination. Living in the future has at least a few perks to go with all the downsides.
Most of them are so expensive, though.
No, Philips, I am not spending $50 on a single bulb, that is madness.
wait insects can't see red? does that extend to spiders? i keep all my windows and doors closed all the time even when its sweating hot because i'm terrified of being invaded by insects and spiders
Though IME, the light quality of a real white LED is better than the mix of an RGB led. Also interesting: the cooler the LED is the higher the quality of the light.
Not doubting you, but how do you define the quality of the light?
There's various metrics, like CQS, CRI or newer versions of it.
It's basically about how close the wavelength spectrum is compared to a black-body radiator given a color temperature (e.g. an incandescent lamp or the sun).
Most "RGB" lights also have 2 white ones of different CCT for a more natural white.
Yes, and blending in between, including RGB, can enhance the quality of light as well to estimate a natural light source.
It's curious seeing people equate warm lighting with old people and old homes. Maybe it's just my region but everybody (especially boomers) switched to CFLs when those came out and then to the cheapest, nastiest cool LEDs with cornea-melting levels of blue light after that. Sometimes I feel like the only sane person when I'm walking around and seeing the insides of houses lit up the same color as you'd get from a $5 flashlight 15 years ago.
I have 4000k in the kitchen and bathroom and 2700K or 3000K everywhere else. After reading this thread I'm considering finding some high CRI adjustables because I also find the 4000k lights pretty harsh at night.
Just heard about a phenomenon where people paint their houses white right before selling them (I assume apartments too) and then the new people won't paint on fairly new paint so they end up keeping the bland colors.
Some people probably depend on their lightbulbs to make the walls look yellow instead of white, I can see those cases comparing the light to a hospital.
I personally like cooler lighting, but there's too much color around to feel like a hospital in my case.
2700K is the closest to firelight. I refuse to abandon thousands of years of archetypal affection for cheap LED false suns.
2700K kin checking in. Fuck those false gods.

Both. Both are good.
Daylight for the work rooms and things like home-office or homework desks, warm light for cozy couch corners and bedrooms.
Or go full high-tech and install lights with adjustable color temperature.

Feel like this is a very US thing. Here in Brazil we just don't use the white light if we can't. Same thing with overhead lighting, we love it here but seems like the US guys just don't go for it
