Ultraviolet lights have many uses. Forensic teams use them to test for blood or other body fluids that may be invisible to the human eye, and there is is also a security strip in US paper money that will glow; the treasury puts it there to prevent counterfeiting. Doctors use them to diagnose certain skin conditions, too. Sometimes they are found at clubs and concerts, and they are also used in some plays and other performances, just because they are cool-looking.
UV lights are better known as "black lights." If you've ever been to the planetarium over by the high school, then you know what I'm talking about. Black lights are those purpley lights they have when you exit that make light colors glow. Personally I love being in ultraviolet light-- it's bright and soothing at the same time, and the way it makes white shine gives you the illusion of seeing in the dark.
Life Lesson: There is more to most things than meets the eye.
