I have LEDs everywhere. But the blue light fears some game seem at least worth looking into. I can’t help but thinking in 50 years people will be replacing phrases like “they used LEAD pipes” and “they sprayed loose asbestos into the attic” with something akin to “they used unfiltered LEDs”

Sunlight has tons of blue light in it (color temperature of around 5800 K). We are going to be fine.

  The catch is that the sun sets in the evening while LEDs continue to shine blue light.

    Most people turn off the lights at night.

      But not at sunset.

        The "cosy warm light makes us sleepy" meme seems to originate in the use of candles for nocturnal lighting prior to the availability of electricity. Their colour temperature wasn't a scientific choice.

All the LED lamps in our home use phosphor-coated LEDs, so they have built-in filters. We have a mixture of colour temperatures, daylight for wakefulness, warm for evenings. Screens are more of a problem than lamps.
