Ultraviolet light is in the region of from 100nm to 400nm wavelength, located in between visible light and X-ray. Especially 200nm ~ 280nm of germicidal UV, so called UVC, destructs DNA and RNA of microorganisms and therefore permanently inactivates microorganisms.
UV lamps for disinfection emit UVC, and among them low-pressure lamp emits 253.7nm monochromatic wavelength, while medium-pressure lamp emits wide range of polychromatic wavelengths around 265nm. Medium-pressure lamp has higher degree of vacuum, more mercury, and higher UV intensity than low-pressure lamp. Medium pressure lamp can be used in various applications as it emits wide spectrum of UV light. Its life is about 8,000 hours.
A special care should be taken in handling an operating lamp as UV may severely hurt your skin or eye. Protective goggle and gown are compulsory when you should handle it.
