But there’s another side to this: in the late evening/night I set all lights (Philips Hue colour lights) in the bedroom and hallway around the bedroom to go to the darkest orange (no blue). This is what I feel gives a comfortable and usable light with as few lumens as possible. Living room also slow dims to very warm white at lower light levels in the evening. The lack of blue light doesn’t matter in itself, but the lower total light level definitely does.
There’s something deeply psychological about this that I feel trigger a feeling of calmness. It just feels right. Perhaps it has associations to late night bonfires or something. Whether it actually matters if it dims to warm or dims to cool I don’t know.
In this context I also appreciate night shift, just for the fact that the screen better matches the ambient light.
