How is the bactericidal effect determined?

It is determined by power intensity, wavelength, and duration of irradiation. For any given wavelength, the power and time must be calculated to achieve the desired level of disinfection.

What are the performance standards for UVC devices?

There is a lack of uniform standards. Consumers should look for third-party testing and certification from organizations like UL, CSA, or DVGW-OVGW. IUVA is working to develop guidance for healthcare providers.

What is the warranty period for this LED?

The product comes with a 3-year warranty. Note that some specifications mention a 2000-hour or 1-year warranty depending on specific conditions.

Client casesThe supplier states that it exports to more than 40 countries and has partnerships with Germany Osram and USA Bridgelux; it also reports exporting since 2011. These are stated market and relationship references, but no named project details, order examples, or independently verifiable case studies are supplied.

Product Q&A

Q:What is the optimal wavelength for disinfection?

While 254nm is common for mercury lamps, 265nm is generally considered optimal as it matches the peak of the DNA absorption curve. However, wavelengths between 280nm and 300nm also offer disinfection effects.

Q:Can UVC help prevent virus transmission?

Yes, based on existing evidence. UVC light has been used for over 40 years to disinfect water, air, and surfaces against pathogens. All tested bacteria and viruses respond to UV disinfection at appropriate doses.

Q:Are UVC disinfection devices safe?

UVC devices must be used properly. The light is stronger than sunlight and can cause skin burns or eye damage if exposed. Some devices also produce ozone. Safety considerations must be addressed in operations manuals and user training.

Q:What is the difference between UVC LEDs and mercury lamps?

Mercury lamps emit nearly monochromatic light at 253.7nm with a broader spectral distribution. UVC LEDs can be focused on narrow, specific wavelengths, making solutions smaller, more portable, and energy-efficient.

Q:Does the peak absorption wavelength of DNA vary by bacteria?

Yes, different types of bacteria have different peak absorption wavelengths, though most are around 265nm. A single wavelength can be used, but optimal absorption varies.
