LIGHT: African violets are grown indoors. They like bright, but filtered, sunlight. Do not place in direct sun. They can also be grown under florescent lights. The lights are usually suspended 12 to 18 inches above the violet for 8 to 14 hours a day.

Fluorescent body paint. Paints and decorations that fluoresce under black light are used in theater and several art forms. A blacklight (or often black light), also referred to as a UV-A light, Wood's lamp, or simply ultraviolet light, is a lamp that emits long-wave (UV-A) ultraviolet light and not much visible light.
