I use one in my houseplants. Actual house plants - there's a dispensary a block away from me for the rare times I feel like getting high.

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 6500k and over the day it warms up to about 3k

Not every lightbulb is intended for living rooms. Some are designed for workplaces...

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.

I wasn’t expecting to feel so seen at this ungodly hour

Cold light is so clinical and miserable, and I refuse to have it in my vicinity at night if I can help it.

3000K or GTFO

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.

2700k ambient indirect, and 4000k direct overhead with 4 times the illumination when we need to see something. One or the other, the ambient ones are synced to power off automatically

I just want to be able to slaughter a pig if I need to. Gotta do that under cool whites my guy.

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.

(Variant: the rando looking for something small for his toilet. “Oh you know, something like 18000 lumens and 60000k”

You value your eyes at all?)

Specifically updated my house to only use daylight bulbs everywhere.

I use lights to see. I don't need stupid orange lights

As a side note, one of the reasons 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).

EDIT: So it turns out part of this which I learned 10 years ago is outdated. The efficiency thing is true but when I went looking for how phosphors (the layer between the LED emitters and the outside, which absorbs the single wavelength light from the LEDs and emits light with different wavelengths) prompted by the points made by another poster, from places like this it turns out that red LED emitters aren't at all used anymore, only UV and blue (whose light the phosphor then converts into light with different spectrum distributions depending on the material of the phosphor). If you search for it a number of recent scientific papers pop up around various such materials.

whole house is setup with daylight bulbs except the dining hall. it has warm lights. I hate it. it's like I'm eating in the dark.

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.

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”.

For the people saying “5kK+ in the office, 3kK- in the bedroom” what do you use in your kitchen? In your bathroom?
