![]() Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. It is also produced by electric arcs, Cherenkov radiation, and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. Ultraviolet ( UV) is a form of electromagnetic radiation with wavelength shorter than that of visible light, but longer than X-rays. Arc welders must wear eye protection and cover their skin to prevent photokeratitis and serious sunburn. Any questions or you can't find what your looking for, call Genesis Lamp at: 1. radiation is also produced by electric arcs. They can be installed in any regular fluorescent fixture. Black Light fluorescent lamps are electrically and physically interchangeable with regular fluorescent lamps. BLB lamps have tubes made of special deep blue filter glass that absorbs nearly all the visible light but transmits ultraviolet, making an external filter unneccessary. BL lamp usage, therefore, may require that an external filter be used that transmits near ultraviolet, but absorbs the visible light that is produced. In addition to near ultraviolet they also produce some visible light which, under some circumstances, may "wash out" the fluorescing effect. ![]() The BL lamps are similar in appearance to standard fluorescent lamps. There are two kinds of Black Light fluorescent lamps Black Light (BL) and Black Light Blue (BLB) types. Black Light is also used in outdoor and indoor advertising window displays, theatrical and television scenery lighting identification and marking of objects photocopy inspection detection of counterfeit money and bank notes petroleum geology stamp examination chemistry embalming luminous instrument panels insect traps and psychedelic lighting. Black Light uses include: inspection for cracks, leaks and other flaws during manufacturing and quality control checks use by cafes and night clubs for fluorescing costumes and decorations.
