No ozone smell when the germicidal lamp operates. Convenient disinfection solution. A distinct odor may be noticed when the bulb is in use, caused by airborne particles reacting to UVC light. This is a normal part of operation, similar to the scent sometimes noticed in sunlit environments. Large irradiation area, suitable for spaces up to 500 sq ft. Standard E27 base for easy installation. Emits 254nm wavelength UV-C light, providing effective germicidal performance for beds, rooms, clothing, and surface disinfection.
