Ultraviolet (UV) light is a short-wavelength not visible to our eyes. UV-C light is in wavelengths of 200-320nm and considered germicidal UV. UVC LEDs are used in scientific and industrial instruments to measure the quality of water, air, and biological samples, and the latest sanitation, disinfection and sterilization methods.
Ultraviolet germicidal irradiation (UVGI) is a sterilization and disinfection way that uses Ultraviolet C (UV-C) light to kill or inactivate microorganisms by disrupting their DNA. UVGI is used for air and surfaces sterilization disinfection.

Output Power Grade
Note :
In order to obtain a better stable output, UV-LED needs a good heat dissipation environment or heat dissipation system. It is recommended that the lamp bead should not exceed 50℃ in working condition.
