When you choose UV product, have you been puzzled by different UV products especially UVC and Far UVC ?
What is UVC: More than one hundred years ago, scientists discovered UVC (also known as germicidal UV). Since then, it has been researched and used in applications such as water purification and preventing the spread of pathogens in hospitals.
The UVC spectrum includes wavelengths of 200 to 280 nanometers, and it is known for its ability to eliminate 99.9% of pathogens such as viruses, bacteria, fungi and mold spores.
Most UVC products(such as low-pressure mercury lamps) use 254 nm wavelength energy because scientists have found it to be the most effective. UVC LED are relatively new on the market, usually 260nm to 280nm. Other products use broad-spectrum ultraviolet light, which is a combination of wavelengths found in the UVA, UVB, and UVC ranges.
Recently, scientists discovered that UVC light can kill SARS-CoV-2 (a virus that causes COVID-19). Therefore, more and more families and hospitals are beginning to use UVC lamps to disinfect the air and surface of objects.
What is Far UVC: In the past ten years, researchers have begun to pay attention to extreme ultraviolet, which uses a lower wavelength range (between 207 and 222nm) for disinfection and is widely used in water purification plants, hospitals, and factory clean rooms. For water sterilization, antibacterial water tanks, direct drinking water, surface sterilization of humidifiers and toilets, and toothbrush disinfection, far ultraviolet UVC LED have begun to show great application value and potential.
How to choose: With the continuous flood of new products into the market, choosing the right UVC product is not easy. When choosing a UVC lamp, it is necessary to consider the optical power and peak wavelength, as well as the light exit angle and the service life of the lamp.
