  1. Its relatively easy to make UV Leds that don't hurt people (UVA) while it is very hard to make LEDs that can do UVC to kill germs or fuck up your skin or retina. There are some LEDs http://www.cel.com/pdf/press/cel_uvc-leds_03262019.pdf but the output is low and they are expensive and inefficient CFL is much better at that job.

  2. Phage therapy is ancient. The soviets experimented a lot with that. It was phased out by antibiotics.

UVA can penetrate the skin up to the derma which is not ideal. UVB are the ones that stop in the epidermis.
