    Probably best to assume sunlight brightness is optimal for circadian rhythm still, (faster effects at that brightness?), but studies have shown light from standard lightbulbs give significant effects on circadian rhythm still, especially if around 500 lux which looks to give full effects in...

Apparently, the liver oscillates continuously based on the person's circadian rhythm, and...

    Vitamin B2 (FAD) (not Light) May Control The Circadian Clock

    Hopefully this won't spur another war on words as the previous discussion on the circadian clock. This study found that the coenzyme FAD (a derivative of riboflavin) control the circadian clock in a light-independent manner. To make the matters even more "metabolic" so to speak, the levels of...
