Many germicidal applications today feature UVC lamp technology, as UVC light is proven to have powerful germ-inactivation properties.
UVC Lamp Design and Engineering
UVC lamps are ultraviolet (UV) lamps that are manufactured to emit UV light at a specific wavelength, measured in nanometers (nm). Ultraviolet light consists primarily of three bands of electromagnetic radiation, UVA, UVB, and UVC. UVC light is emitted in the range of 100 to 280 nm, with shorter wavelengths than UVA (315-400 nm) and UVB (280-315 nm) light.
When emitted from the sun, the majority of UV light that reaches the Earth’s surface is in the UVA range, with some in the UVB range, and UVC radiation is completely absorbed by the ozone layer. Germicidal UVC lamp manufacturers design, engineer, and manufacture UVC lamps to emit electromagnetic radiation in a specific wavelength to meet application requirements.
UVC Lamp Germicidal Applications
UVC light is proven to have highly effective germicidal properties, eliminating many types of bacteria and viruses, as well as preventing mold and mildew. This makes UVC lamps a very important part of many types of disinfection systems used in residential, commercial, and industrial applications.
UVC Lamps for Air Purification
UVC lamps are used in UV air disinfection systems in just about any setting to improve indoor air quality and prevent the transmission of harmful airborne germs. UV air disinfection systems protect the health of people in many environments, including residential homes, hospitals and medical facilities, schools, restaurants, public transportation systems, and more.
UVC Lamps for Surface Disinfection
Many UV surface disinfection systems feature UVC lamp technology to prevent the buildup of harmful germs in places like commercial kitchens and laboratories. UVC lamps are commonly used to protect patients in hospitals and operating rooms and to disinfect medical devices.
UVC Lamps for Water Disinfection
UVC lamp technology is used in many water disinfection applications and provides safe and efficient germicidal effectiveness. UVC lamps are proven to eliminate some harmful germs in water that chlorine cannot, such as Cryptosporidium and Giardia. Germicidal UVC lamps for water disinfection provide many advantages over chemical use alone.
UVC Lamp Types
UVC 185nm Ozone Lamps
UVC light in the range of 185 nm produces ozone, which is an effective deodorizer. Ozone lamps are used in a variety of air and water purification systems. Ozone lamps for air purification have the advantage of producing UVC radiation that does not require direct line-of-sight exposure for germicidal effectiveness. Ozone can reach places that other UVC lamps cannot and are effective at eliminating foul odor in the air and volatile organic compounds (VOCs).
UVC 254 nm Disinfection Lamps 
UVC lamps designed to emit 254 nm are the most common types of UVC germicidal lamps used in a variety of disinfection systems, including air, surface, and water. UVC light at 254 nm quickly eliminates many bacteria and viruses by penetrating the cells and altering the DNA to prevent cell replication. UVC light at 254 nm is proven to eliminate many types of bacteria and viruses, although the correct type of UVC lamp must be used at the right dosage to meet the requirements for specific pathogens. UVC light is proven to eliminate many antibiotic-resistant superbugs and many viruses, including SARS-CoV-2, the virus that causes COVID-19.
The rate of effectiveness at eliminating various types of bacteria and viruses depends on the type of microorganism, the intensity of the UVC lamp, and the duration of exposure.
222 nm Excimer Lamps
UVC light in the range near 222 nm, also called Far UVC, is becoming more popular for many germicidal applications. Far UVC lamps are proven to have many similar disinfection properties as 254 nm lamps, although they can be safer for human exposure under the right conditions.
