| Ultraviolet light cannot be seen unless it is reflected from special UV paint which shifts the light
wavelength
from the invisible UV range to visible light. On the stage, this phenomenon is used to create the effect of a totally dark
stage
with specially painted scenery and makeup or naturally fluorescent fabrics, which will be seen when the UV light is turned on. |

Ultraviolet (UV) light is produced when an electrical current is passed through mercury vapors, and is also known as black light. Ultraviolet lamps are available in a pear shape
envelope
at 70W to 400W, and in 10W to 40W fluorescent tubes.
UV filters are also available, making it possible to use a powerful luminaire such as a follow-spot, for black light effects. However, this method is not as efficient as using a special UV lamps. |
