The lamp itself looks like a typical high pressure sodium type - basically
tubular with a bulge in the middle. But the light it gives off is an
extremely intense blue. What's in there, and what is the rationale behind
illuminating a compound with this colour ?

It's suppose to prevent suicides and crime:

Maybe that's why I never committed any crimes while under a black
light. Or, maybe I was too stoned to do anything. Dunno.

Unfortunately, I can't determine what type of lighting is used. I
don't think it's LED or CFL but it's possible. It might also be a
mercury vapor arc lamp which belches lots of blue and UV. Google and
Bing won't tell me.

If you're into blue, here's a mess of nature photos in blue that are
suppose to be relaxing:

It was Kmart that had a highly irritating "blue light special" and
BlueLight internet dialup service. Yech:

Maybe it's Kmart coming back from the near dead?
