I was told it was to make it hard for people using needles to find their vanes. It turns out it's just the phosphor coating coming apart. The LEDs used to energize that to make the broad spectrum light are usually blueish purple for maximum efficiency.


It does do that and it's used for that.

I first experienced that in a bathroom in England. Door open, regular white light. Lock the door, blue light. I thought I broke something when that happened.


Makes the cocaine easier I see too! Social economic apartheid for the win!


It's harder to find a vein with it. It's not for efficiency.

Though linking it to the lock isn't terribly useful, most heavy addicts won't care if anyone opens the door on them.
