Deep LED Ultraviolet-C disinfection effectively reduces microbial load on surfaces of devices incompatible with chemical disinfectants or heat. It is recommended as a routine disinfection measure for hospital infection control. This study demonstrates high efficacy under controlled conditions; however, real-world effectiveness may be influenced by factors such as device positioning and surface shadows.<\/jats:p>\n
