Concern was mentioned on another board about the whole UV and germicidal bulbs thought the following info would be informative as to what safe uv (blacklight) and the bands of uv you don't want to encounter. Be assured the cc lights you use in your cases are safe!
Ultraviolet Light is an invisible band of electromagnetic radiation beteween x-ray radiation and visible light. It is defined
as electromagnetic radiation between 100 and 400 nanometers (nm) and is arbitrarily broken down into three bands, according to its anecdotal effects. UV-A 315 to 400nm, UV-B 280 to 315nm and UV-C 100 to 280nm
UV-A is the least harmful and most commonly found type of UV light, because it has the least energy. UV-A light is often called blacklight, and is used for its relative harmlessness and its ability to cause fluorescent materials to emit
visible light - thus appearing to glow in the dark Most phototherapy and tanning booths also use UV-A lamps.
UV-B is typically the most destructive form of UV light, because it has enough energy to damage biological tissues, yet not quite enough to be completly absorbed by the atomsphere. UV-B is known to cause skin cancer. Since most of the extraterrestrial UV-B light is blocked by the atmosphere, a small change in the ozone layer could dramatically increase the danger of skin cancer. UV-B is most commonly used for UV curing and molecular biology.
Short wavelength UV-C is almost completely absorbed in air within a few hundered meters. When UV-C photons collide with oxygen atoms, the energy exchange causes the formation of ozone. UV-C is almost never observed in nature, since it is absorbed so quickly. Germicidal UV-C lamps are often used to purify air and water, because of their ability to kill bacteria
