You might ask, exactly what is black light? If you turn on a black light bulb in a dark
room, what you can see from the bulb is a purplish glow. What you cannot see is the ultraviolet
light that the bulb is also producing. Our eyes can see the visible light in a
spectrum ranging from red through orange, yellow, green, blue and violet. Above violet is
ultraviolet light, which we cannot see.
What you see glowing under a black light,
whether it is a fluorescent poster, something you've painted with fluorescent paint or a
newly-washed white T-shirt, is different phosphors. A phosphor, is any substance
that emits visible light in response to some sort of radiation. In other words, a phosphor
converts the energy in the radiation into visible light. So a fluorescent paint contains a phosphor
that converts UV radiation into a specific color of visible light.
Normal colors simply
reflect light, but a fluorescent color absorbs the radiation and re-emits it in the
visible spectrum, sort of like a light bulb emits light, so it looks much brighter than a
normal color. Black light units and there accompanying bulbs
come in a variety of sizes, anywhere from six inches to four feet in length. Most are AC
powered, but you can also get some of the smaller ones in battery powered.
