Please, help me out here: LED can be bought at different temperatures. Why is this an LED problem and not a they-use-daylight-temperature problem?

Because itβs not just about color temperature, which is a superficial metric. It involves light spectrum, flicker rate, so forth. LEDβs in the conventional sense offer isolated blue light, which is very damaging to a circadian system that evolved for full spectrum sunlight during the day and darkness at night.
This gives you one example of the harms involved with the eyes

I have 2700 LEDs at my house. I wear blue light blocking glasses at night. Thank you for sharing the article, I'll see if I need to replace my lights. LEDs are gentle on the electricity bill, but I don't want to get sick.
Took me a moment to realize you were saying you had 2700K LEDs. I thought you were saying you had 2,700 LEDs at your house. π
You don't know my house! I have 12 of these... per bedroom!
