UV Wavelength (nm)
UV wavelength measured in nanometers (nm). Determines the strength of the germicidal bulb. UVA 315-400nm, UVB 280-315nm and UVC under 280nm.
UV Irradiance (uW/cm2)
Measurement of the radiant power. Measured in watts per square centimeter at one meter distance. Helps to determine the amount of UVC energy upon a certain area.
Utilizes UVC
UVC is ultraviolet light, a component of the electromagnetic spectrum that falls in the region between visible light and X-Rays. It can be harmful if proper safety precautions are not followed.
