Artificial light, especially led very relevant and becoming an important subject to take seriously in my opinion. The color spectrum aswel as the insane flickering led diodes create wich is not seen by our eyes but very well by your biological body. Also every led diode is powered by an driver chip for the precise voltage and ampères. These drivers are known for their emf radiation potential.
