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.

Nah 3kK is cool enough for work unless you’re like a graphic designer that needs to see colours accurately. 2.7kK for the rest of the house btw

We have a “sunshine” script in Home Assistant that sets all bulbs to daylight and 100%. Great for livening up overcast days.

I may be ahead of the curve a bit. Adjustable colour temp didn’t seem enough. My whole apartment has RGB bulbs since about 5-6 years ago. I just couldn’t go back to on/off one shade lights ugh.
Also I rock a 300w LED panel to get a bit more brightness in my winter days, but that’s not RGB though.

I’m like this, home office, kitchen, bathroom etc is daylight like 5k, only the bedroom and a corner lamp in the couch room are 3k.

Personally I just go for warm white for places which should be cozy and cold white for places with a more utilitarian use.
Cold white LED light bulbs are actually more efficient, so I’ll even get more light out of the same power lamp making it easier to see what I’m doing (which is what you generally need lights for in an utilitarian use location).

Warm white is usually 1800 K to 3000 K. What you showed is less Kelvin than the color temperature of fire (1500 K). We don’t have a color temperature word for that, but “red” works. Of course, such light has no blue component (helps control the cicardian cycle) and is pretty much monochromatic with CRI of <5.

Personally though, something under 1500K is perfect for me as bedtime approaches. It primes me to fall asleep quickly

This is why I don’t use them.
The paint in my living room looks diarrhea brown and corpse gray under warm light. It’s purple and blue, and there are a lot of windows so I can’t plan for warm light as a default. Daylight bulbs keep the color what it should be.
ragebutt@lemmy.dbzer0.com 5 hours ago
Modern led bulbs can do both and then with home assistant you can script it so the color temperature changes through the day as the sun changes.
In the morning my house is cool light around 3k and over the day it warms up to about 6500k
teuniac_@lemmy.world 52 minutes ago
You don’t even need to script it. Just use the Adaptive Lighting custom integration. You can sync your light color temperature with the sun, or customize it any way you like.

Daylight bulbs are everywhere in Japan and it’s so strange. I tried looking for warm light bulbs at a local store and they don’t even stock them as an option. I do see them used in some people’s houses so I’m sure it’s not universal, but the prevalence of daylight/cool bulbs is weird to me, I’m very much warm bulb gang.

Could you find adjustable LED bulbs? Those are honestly the best of both worlds. Daylight is great for things like cleaning, but I much prefer warm light for general living.

I dunno why, but warm lighting at night just makes me feel depressed. I need daylight bulbs across my house. Adjustable brightness preferred though, so I’m not blinding myself at night.

I was gonna flame you but the reality is both have their place. Sunlight bulbs in hallways and bathrooms looks awful. You can’t see shit and they cast long shadows which makes visibility worse. Daylight bulbs are great for those areas.
That said daylight bulbs are too harsh in the living areas so I understand both sides.

The wavelength has negligible effect on shadow geometry. What do you mean? Also, sunlight and daylight is pretty much the same thing.

Part of my job is selling lighting.
The following conversation takes place at least once a day without falter:
X: I’d like one light like this please (puts some form of light on the table)
ME: ok (goes through the script to make sure they know what they want/it’s compatible/…yaddayadda).
X: oh and it needs to be warm in colour.
ME: 2700k got it.
X: yes, but like warm right? Because it’s led.

“You want cold white or warm white?”
“I need a cold light source, like an LED. I’m afraid the fixture would melt if I put incandescent in there.” (Yes, some E14 fixtures in cheap plastic bathroom mirrors etc. only take up to 10-20 W and have a warning sticker)
“What, higher temperature is colder?” (It’s not their fault though that in nature, white and blue things 🧊 are generally colder than yellow and orange things 🔥)

Do people actually confuse color temperature with operating temperature? I wouldn’t want any lights in my house if their operating temperature was ≥2700 K.

Aceticon@lemmy.dbzer0.com 10 hours ago
As a side note, the reason why cold white LED light bulbs are a thing is because they’re a bit more efficient than warmer light colors.
The reason is because they all just have 2 kinds of light emiting diode (LED) junctions inside - red and blue - plus a phosphorus layer on top that smooths those two perfect lightwave color peaks in the wavelength domain into a broader light spectrum, and the blue is more efficient than the red, so lamps with a higher proportion of blue emitters to red emitters - and which hence emit more light towards the blue end of the spectrum (i.e. a colder white) - will emit more light for the same power consuption than those with more red emitters and hence whose light is more towards the red side of the spectrum (i.e. a warmer white).

There’s practically no chance this knowledge will ever benefit me, but I’m happy to learn something new regardless. Thanks for sharing!
Fedizen@lemmy.world 7 hours ago
It seemed odd the lower frequency diodes would be less efficient so I did a quick bit of reading and it seems like red light is efficient, but red and blue light aren’t as effectively picked up by the human eye as green and because each light has a different operating voltage there are some consequences.
From what I read the things that makes white lights more effiecient is they only use blue diodes which probably means less circuitry is needed to operate two sets of alternating diodes and there’s less difficulties going from higher frequency (aka higher energy) to low via filters. Hence efficient green light, blue light and red light.
Aceticon@lemmy.dbzer0.com 6 hours ago
From what I read last time I properly looked into this (so, almost a decade ago when I was considering setting up a business importing LED lamps), the blue light emitting diode junction simply uses less power to emit the same amount of light.
Electrically speaking it’s no bigger or lesser a problem in terms of circuitry to have just blue diodes or blue + red diodes in there since they’re bundled in blocks of diodes in series (and then multiple blocks are in parallel) and the only thing that differs between those two kinds of junctions from a circuit point of view is the drop voltage of one kind of diode being different from that of the other (diode junctions done with different dopants have different drop voltages), something you take into account in the design stage when deciding how many LED diodes you use per block or what DC voltage will your 110v/220V AC input be converted to.
More specifically for LED light bulbs, the messy stuff in terms of electronics is the circuitry that converts the 220v/110v AC input into a lower voltage DC suitable for the LEDs whilst limiting the current (as diodes only ability to “limit” current is them burning out from overheating due to too much current), not the actual LEDs.
But I’ll put it even simpler: if the problem was indeed simplicity as you believe, then LED bulbs with only red LEDs would also be very common as they’re simpler than blue+red ones.
RememberTheApollo_@lemmy.world 10 hours ago
I have an actual full-spectrum daylight bulb and it’s pretty good. I use it when the days get really short, seems modestly effective. It’s not the typical “warm” lighting, it’s much more actual daylight. I can’t stand those hard white almost blueish light bulbs. Makes things feel industrial and cold. No idea why anyone calls them “daylight”.

White light is a must for makeup, or any time where you need to see colors accurately. Otherwise give me yellow all the way lol. I love the coziness.
ChaoticNeutralCzech@feddit.org 10 hours ago
The difference is not as pronounced as in the picture. If you’re used to 4000K as neutral white, yellowish white is 3000K, amber-ish white is 2700K. Only below the temperature of fire (cca 1500K) is when blue fully disappears and you get actual orange or red. And pure yellow is not a possible black body (incandescence) spectrum (that is, it does not correspond to any color temperature) so even though you can set an RGB bulb to that, buy monochromatic yellow LEDs or go under a low-pressure sodium vapor lamp, such lighting feels unnatural.

I’m surprised to see pretty much all the comments stating that they prefer the warm lights. It hurts my eyes and feels very awkward to have light coming in through windows into a room with warm lighting, so I mostly use daylight bulbs.
Do warm lighting people just keep the lights off when their curtains are open, or am I alone in this issue?
Foxfire@pawb.social 10 hours ago
When my curtains are open, I’m getting ample sunlight and don’t need lighting. When it’s night time, I don’t want light which emulates daylight in my home.

Warm white 2700-3000k is fine for bedrooms Soft white 3500k is better for awake spaces that aren’t task spaces White/Daylight 5000k+ is for getting things done, I use them in the garage, the basement, and for some of the kitchen lights
I used to hate integrated LED fixtures, but I put in under-cabinet lighting that can switch color temp so that is nice because I can set it to daylight during meal prep and warm during eating.

I want my home to have full range color equivalent to open windows. But I prefer my lights to change color with the sun so as not to mess with my circadian rhythm. Incandescent color bulbs just remind me of being a kid visiting the elderly. I’m mostly a “open the blinds instead of turning on a light” purist during the day.

We accidentally installed a white light bulb in the hallway outside my bedroom. It made me feel so pissed off and on edge every time my door was open and someone turned that light on.
Once we swapped it to a warm bulb I was much more chill.
I do keep a tunable light bulb in a task lamp, but the rest of the lighting in the house is warm.
ChaoticNeutralCzech@feddit.org 11 hours ago
This scale feels wrong. 4000K is neutral white and should have no hue. Of course, that depends subjectively on what the light around is. 6000K should only be in the center if you’re outside a lot. And the difference between 6000K and 10000K is greatly exaggerated. Not even the visible portion of “infinite” Kelvin is that blue if 6000K is calibrated to white.

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.

I have a couple lifx bulbs and my partner brought like 8 cheapo Chinese ones with her when we moved in together. It is quite nice. The LIFX bulbs give much higher quality light and better color, but the ability to schedule lights on and lights off is incredibly nice. I would not recommend WiFi bulbs to anyone for the following reasons:
Overall the WiFi bulbs suck complete ass and I’m keeping them because the lady likes them and it works so long as I don’t touch anything. I’d like to try using zigbee bulbs because they solve a lot of the problems I have with WiFi bulbs but replacing the system I have would be expensive, even after liquidating the old ones on eBay.
