UV germicidal lamps are a type of electric light that emits ultraviolet-C (UV-C) radiation to kill bacteria, germs, and other microorganisms. The UV-C light deactivates the microorganism’s DNA, destroying its ability to multiply. UV germicidal lamps sterilize surfaces and air in many diverse settings, from hospitals to water treatment plants, commercial spaces, and more.

How UV Germicidal Lamps Work

UV light is a type of electromagnetic radiation that cannot be seen by the human eye. It is categorized between visible light and x-rays on the electromagnetic spectrum and is classified into three types based on wavelength: UV-A, UV-B, and UV-C. Out of these three types, UV-C light has the highest amount of energy and the shortest wavelength. Due to its effectiveness at killing microorganisms, it is also referred to as germicidal UV.

Germicidal UV lamps work by emitting UV-C light at a specific wavelength that is most effective for killing bacteria and germs. Typically, this wavelength is between 100 and 280 nanometers (nm). There are different types of UV germicidal lamps available, with outputs tailored to differing disinfection needs:

  • Low-pressure lamps. Featuring a lower UV output, these lamps are suitable for air and surface disinfection applications. They create UV-C light using a low-pressure mercury arc and are most commonly found in portable disinfection devices, such as handheld wands.
  • Medium-pressure lamps. This type of lamp uses a high-pressure mercury arc to produce a higher output of UV-C light. They are suitable for larger disinfection systems and are most commonly used in water treatment and purification applications.

Common Uses for UV Germicidal Lamps

UV germicidal lamps are used in a wide variety of applications, including:

  • Deodorizing commercial and residential spaces. Germicidal lamps eliminate odors and improve indoor air quality in homes, restaurants, hotels, and virtually any other indoor space. They work by killing the types of microorganisms that cause odors, resulting in enhanced overall air quality.
  • Disinfecting and sterilizing air and surfaces in hospitals and healthcare settings. UV germicidal lamps are very valuable in medical-related applications. Since they are highly effective at killing bacteria and germs both on surfaces as well as in the air, they are a key tool for limiting the spread of infections. They are commonly used in hospital patient rooms, operating rooms, and other high-risk areas to help reduce the spread of illness.
  • Enhancing indoor air quality. UV light kills the microorganisms that grow in moist HVAC systems. When used in conjunction with heating, air conditioning, and ventilation systems, germicidal lamps can eliminate bacteria and mold from the air and improve respiratory health.
  • Water treatment and purification. The light from germicidal lamps is effective against waterborne bacteria, protozoa, and viruses. They are an environmentally friendly method of killing these microorganisms without harmful chemicals or by-products.

Benefits of Using UV Germicidal Lamps

In applications where sterilization and cleanliness are required, using UV germicidal lamps offers many advantages over other disinfecting methods:

  • Effectiveness. Germicidal lamps are highly effective at killing bacteria and germs, providing reliable sterilization.
  • Efficiency. UVC light disinfects quickly, providing fast-acting sterilization of an area.
  • Chemical-free. Unlike bleach, chlorine, and other chemical disinfectants, UV germicidal lamps do not produce any harmful by-products or leave any residues behind.
  • Versatility. UV lamps disinfect surfaces of various sizes as well as the air and water, making them suitable for a number of diverse applications.
