UV Irradiance is the radiant power, within a stated wavelength range, arriving at a surface per. unit area, usually expressed in watts or milliwatts per square centimeter. Irradiance varies with lamp. output power, efficiency and focus of its reflector system, and distance to the surface.
UV Light. UV light is measured in microwatts of ultraviolet radiation per lumen of visible light (ÂµW/l). The high energy of UV radiation is particularly damaging to artifacts. UV light is not visible to the human eye and therefore removing it from museum lighting causes no change in appearance. Daylight is generally the strongest source of UV light; fluorescent, metal halide and mercury vapor lights also emit UV radiation.
