I replaced all the light switches in my house with smart dimmers and have the lights dim in the evening. It happens in steps so it's noticeable and it's like a clock ticking down. I don't know if there's anything scientific about it but it's pleasant, like the house is going to sleep so maybe I should too.
I like to use the yellow anti-insect lights for the external lighting around my house as they tend to attract way fewer flying insects and fewer spiders as a result.
I also like them in lamps inside for illumination during the evening, with the added benefit of not requiring more IoT devices.
This is especially nice if you use bulbs that get warmer as they dim. (See the Kruithof curve.)
