Humans evolved on full spectrum light from a heat source of the sun or fire wood. LEDs generate no heat and lack spectrum. LEDs are blue limited spectrum. Real light requires a heat source, and higher energy and higher expense.
LEDs CANNOT simulate light. Ever. It is impossible without a heat source.
This is why humans get sick on LED lights.
This is why you get sick long term on LED food.
What part of science are you all missing?? What you don’t know, CAN hurt you.
China has put cardboard in food.
It looks like food. It has the same color as food.
People eat it.

Your ignorance of basis physics is amusing.
