Modern bright lighting is great for daytime but one of the worst things we can do to ourselves in the evening or night. We absolutely did not evolve to be exposed to bright (particularly blue/white) light after the sun starts setting.

The best thing I did for my circadian rhythm was eliminate light in the bedroom and set up my lights to slowly shift to soft amber and dim in the evening. The trick is having it transition slowly so your eyes adjust and you don't notice it.
