    The center is 3000K tho

      Used 5000K because it is missing from OP’s post for some reason.

  I use red bulb (or just leds now) unironically, I can see good enough to walk at night and they don’t fucking hurt my eyes like dumbass white bulbs. Seriously how do people use those white bulbs? Just going to a hospital is painful.

  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

      I’m not saying it’s a bad idea, I have a red bulb too. It’s “handmade” by removing thick red rubber from a “golf ball” decorative 7W CFL and stretching it over a similarly-sized 6W 2700K LED that has instant start and higher light output. It is not as monochromatic as pure red LEDs, I think it’s close to what the phosphor-based red ones emit but those are marketed as cicardian too. I have to avoid ooking straight into it though: the pupil is wide open because rods don’t react strongly to red light so long-wavelength (red) cones get massively overloaded and you see a green spot for a while.

  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.
