Germicidal UV-C

The UV-C portion of the ultraviolet spectrum includes wavelengths between 100nm and 280nm. The wavelength with the greatest lethal effectiveness is 253.7nm which defines the germicidal category. For water sanitation, ozone production is an additional requirement. If you know the bulb description for your applications use the column on the left below.

Germicidal Light Uses

Germicidal or Ultraviolet Germicidal Irradiation (UVGI) lamps are used to disinfect air and water; cure inks and coatings, disinfect foods and destroy pollutants in water and air through UV-based "advanced oxidation".

UV energy can be effective in killing biological contaminants such as mold/fungi, bacteria and viruses. For air disinfection, lamps are typically placed inside air handling ducts, mobile room air cleaning units and in special fixtures mounted toward the ceiling in rooms. The most common applications are in hospital / health care facilities, food processing plants, shelters, prisons, and other commercial uses where it is important to eliminate biological contaminants. The target wavelength for most ozone-free air purification applications is 254 nanometers. For water purification, ozone producing wavelengths are included and the target wavelength is 185 nanometers.

Warning: UVGI radiation is extremely harmful to skin and eyes.
