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.
And new, improved forms of protection against UVA keep emerging. Keeping up with these new developments is a worthwhile challenge that can help all of us prevent sun damage. What is Ultraviolet Radiation? UV radiation is part of the electromagnetic (light) spectrum that reaches the earth from the sun. It has wavelengths shorter than visible light, making it invisible to the naked eye. These wavelengths are classified as UVA, UVB, or UVC, with UVA the longest of the three at 320-400 nanometers (nm, or billionths of a meter).
