What Should I Pay Attention to When Buying UV Sterilizer Lamps?

UV technology can deactivate bacteria, viruses and fungi to make them no longer harmful. Ultraviolet UV-C band sterilizes in the range of 253.7nm and is effective against any bacteria and viruses. UV disinfection is a physical process that does not involve the production of toxic, harmful or corrosive chemicals. It can effectively kill the new coronavirus and other viruses, and it can also disinfect and remove mites.

UV sterilizer lamps are also called ultraviolet germicidal lamps and ultraviolet fluorescent lamps. It is a lamp that uses the sterilization effect of ultraviolet rays for sterilization. The effective sterilization wavelength of the UV sterilizer lamp is 253.7nm, and the 253.7nm ultraviolet ray has the strongest sterilization ability and can be used for disinfection and sterilization of air, clothing, water, etc. The bacteria and viruses on the clothes can be killed by being irradiated by the uv lamp for about 5 minutes. It can also be used for air disinfection in laboratories and operating rooms that require clean air. The bacteria in the air can be killed after 30 minutes of irradiation.

So where do you need to look when buying a ultraviolet light?

1. See specifications

UV sterilizer lamps are classified into 15W, 20W, 30W and 40W according to their specifications, and the operating voltage is 220V. According to the space required for use, such as area: 20㎡-50㎡, choose different power UV disinfection lamps. In principle, the greater the power, the better.

2. Look at the voltage

UV sterilizer lamps are divided according to voltage, and are mainly divided into: high pressure, medium pressure and low pressure. Daily sterilization and disinfection applications are mainly low pressure. According to national standards, the average life span is 8000 hours. The life of some excellent UV germicidal lamps has reached 13,000 hours.

3. Look at the light source

According to the lamp source, it can be divided into: low pressure mercury lamp and UV LED lamp source. The low-pressure mercury lamp used in the UV mercury lamp uses low-pressure mercury vapor to emit ultraviolet light after being excited; the UV LED disinfection lamp uses an LED light source to emit light. Both low-pressure mercury lamps and UV LED disinfection lamps are very effective sterilization methods. The difference is that there are two main spectral lines emitted by the low-pressure mercury lamp: one is 253.7nm wavelength; the other is 185nm wavelength, both of which are invisible to the naked eye.
