Not mentioned anywhere above is the psychological effect of lighting. I worked in sales, but the factory had different lighting. Management decided to replace the existing fluorescent lighting with much brighter sodium lighting.
The sodium lighting had an orange/yellow color. The factory workers were convinced that the lighting was causing headaches. After weeks of arguing with the union, management caved and the old lights were restored.
Management’s position was that the headaches were imagined.
If you think you have a headache and it hurts, does that not mean that you do have a headache.
On the other hand, magenta colored lighting is supposed to reduce the synaptic response in your body (pain receptors). The effect is supposed to be slow (hours) but it is supposed to create a subtle level of euphoria.
I tried this once, but with no way to measure the results, I could not get a reading on my euphoria.
High pressure sodium lighting is still used in street lights (but not much from my experience).
It still has a place as a “grow” light:

There are a lot more sources for magenta lighting nowadays, in case anyone wants to work on their euphoria. [big grin]
