Thanks to the single-ended lamp base, lamp replacement is easy.The OSRAM TUV series ultraviolet sterilization lamps operate in the ultraviolet UV-C band, with the strongest sterilization power in the range of 250-270nm. Due to the resonance spectrum line of mercury being 2537A, this sterilization tube can generate 253.7nm ultraviolet light, causing denaturation of bacterial and viral DNA and RNAV, and preventing cell proliferation. Ultraviolet disinfection lamps are effective against any bacteria or virus, and concentrated high intensity ultraviolet rays can sterilize in a short period of time
