I have not, but I turn off my lights when I go to bed.

Let me guess: you've switched from yellow light to white light?

White lights emit more blue light than yellow lights, which can negatively affect your sleep. It's the real-world equivalent of uninstalling redshift/f.lux on your device.

I've invested in "smart" LEDs and I change their color based on the position of the sun. If the sun is up, the light is white. If the sun is down, the light is dimmed orange.

No, but all my LED bulbs give off a yellow light instead of a white light.

As I understand it, even though LED output is yellow, the primary light range emitted is blue. No idea if this study [1] is good, but the abstract explains it a bit.
