A germicidal lamp is a type of ultraviolet (UV) light that is used to kill or inactivate microorganisms, such as bacteria, viruses, and fungi. These lamps emit UV-C radiation, which is effective in disrupting the DNA or RNA of pathogens, preventing them from reproducing and causing infections. They are commonly used in hospitals, laboratories, and water treatment facilities to maintain a sterile environment. In addition to healthcare settings, germicidal lamps are also utilized in residential and commercial spaces for air and surface disinfection. They can be found in products like UV sterilizers and air purifiers, helping to improve indoor air quality and reduce the spread of illnesses. Proper safety precautions are necessary when using these lamps, as UV-C radiation can be harmful to skin and eyes.
