UV-C germicidal light fixtures utilize short-wavelength ultraviolet light to inactivate micro-organisms like bacteria, viruses, and mold. These devices emit UV-C radiation, which damages the DNA of those pathogens, preventing them from reproducing. UV-C technology is often used in healthcare settings, food processing facilities, and public spaces to maintain a hygienic environment. Use Caution: UV-C radiation can be harmful to human skin and eyes, so it's important to use these products safely and avoid direct exposure to the UV-C light rays.
