This was an yet another glorious episode from veritasium.

I hope we get well past UVC LEDs. (i.e., shorter wavelengths) UV LEDs are already available. Unfortunately, this progress will stop before X-ray light. With +1 KeV energy, you pretty much must blast off the electrons from the atoms to emit X-rays, which an x-ray tube already does. Or by peeling off a piece of scotch tape.

Maybe making X-ray emitters cheap enough to put in a flashlight isn't the best idea anyway.
