1, principle difference: LED germicidal lamp uses LED to emit ultraviolet rays with a specific wavelength to kill bacteria and viruses through direct irradiation, and ultraviolet germicidal lamp uses ultraviolet rays for disinfection and destroys DNA and RNA of microorganisms to achieve sterilization effect.
2. Difference of light wavelength: LED germicidal lamp mainly emits ultraviolet rays in UVC band, and ultraviolet germicidal lamp emits ultraviolet rays in UVA or UVB band.
