Old flourascents lights.

what it is, I like to wear print/horizontal/verticle lines (whatever
they are called?) shirts.What it used to be like back in the 1950s,
riding in a car underneath the Train overpass with those old timey
flourascent lights thingys, it was like my shirts would change color on
me.y'all old timers ever had similar experiences before? (I know some of
y'all have)

Cuhulin-

You may be referring to fluorescent lamps that emit a lot of ultraviolet
energy. Some materials light up when lit by ultraviolet light, which is
how the lamps work to begin with.

At one time, there were ultraviolet fluorescent tubes available called
"black lights", that had almost no visible light. As far as I know,
these lamps were made in common sizes that worked in existing fixtures.

These lamps may have been intended for industrial and medical
applications, but were adopted for use in night clubs and parties
because of the neat effect they produced.

If you intend to experiment with black lights, be careful. Even though
you can't see ultraviolet light, it can damage your vision.

Fluorescent and mercury-vapor lamps do not have a continuous spectrum, and
their color temperature does not match that of either daylight or household
tungsten lamps. So colors will change under them.

That's a very broad statement without qualification.

Yes, it is. I didn't have time to go into excruciating detail about modern
photographic fluorescents, color-rendering index, etc.

Cut me a break. Please.

I almost got involved there, but bit my tongue instead .... :)

I have a small hand held black light around here somewhere, I bought it
at the Goodwill store about fifteen years ago, it works too.It would
take me forever to find it though.

About twenty years ago, I was watching a tv program about germs on
kitchen countertops and things.They cleaned off a kitchen countertop
real good with household detergent.Then they turned off the lights and
turned that black light on and they moved that black light around real
close over the countertop.It was amazing to see there were still a lot
of germs on top of that kitchen countertop.

I think stores which sell scientific thingys also sell black lights.
