Light quality has been something I've been interested in for a while so I've invested in making my whole environment use LIFX and Yeelight bulbs.

This has been great and I get bright neutral lighting during the day, warmer light in the evening and variations of colour gradients and themes when friends are over to chill.

However, I have no way of knowing if something is missing from the light quality or how I'd even go about optimising things both for my health/comfort and for indoor plants. Does anyone have recommendations?
