The typical wavelength ranges of UV LED lights can vary depending on the specific type of LED and its intended application. However, generally speaking, UV LED lights emit ultraviolet light in the range of 280 to 400 nanometers (nm). This range is further subdivided into three main categories: UV-A (400-315 nm), UV-B (315-280 nm), and UV-C (280-100 nm).
UV-A LEDs, also known as blacklights, emit longer wavelength ultraviolet light and are commonly used for applications such as fluorescent inspection, counterfeit detection, and bug zappers. UV-B LEDs emit medium wavelength ultraviolet light and find applications in medicine, phototherapy, and plant growth. UV-C LEDs emit shorter wavelength ultraviolet light and are primarily used for sterilization, germicidal applications, and water disinfection.
It’s important to note that UV LED technology is rapidly advancing, and there may be variations in the precise wavelength ranges depending on the specific product or manufacturer.
