We are committed to research and development, producing greener, energy-saving and high-quality products. We have professional laboratories and researchers, and have conducted rigorous testing to ensure scientific effectiveness. We provide free consulting services for all your business growth project needs.

The ultraviolet spectrum important for water and air disinfection is the range absorbed by DNA (200-300nm). While 254nm was traditionally used, our testing shows that 265nm, 275nm and 280nm UVC LEDs provide optimal disinfection as they match the peak of the DNA absorption curve.

UVC LED power intensity, wavelength and irradiation duration determine bactericidal effect. For any given wavelength, the power and exposure time must be calculated to achieve the desired disinfection level.

UVC LEDs are smaller, more powerful, non-toxic, have longer lifespans, and are more energy efficient than mercury lamps. They allow instant optical output and can be tailored to specific wavelength requirements, unlike mercury lamps which emit a fixed spectrum.

Our 265nm-285nm UVC LEDs are used in ICU hospitals, air purifiers, water purifiers, washing machines, UVC boxes, and UV light sterilizers.

We have professional laboratories and conduct extensive testing to ensure product effectiveness. We welcome your project engineering drawings and offer free consultation services for all your commercial needs.
