Product Q&A

Q:What are the main applications of this UVC LED?

It is used for sterilization, disinfection, phototherapy, fluorescent spectroscopy, sensor light, bio-analysis, and counterfeit detection.

Q:What is the optimal wavelength for disinfection?

While 254nm is common for mercury lamps, 265nm is generally considered optimal for DNA absorption. This product operates at 275nm within the effective 200-300nm sterilization range.

Q:Is UVC light safe for human exposure?

No, UVC light is much stronger than sunlight and can cause severe skin burns and eye damage. Proper safety measures and training are required.

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

UVC LEDs are smaller, more powerful, non-toxic, longer-lasting, energy-efficient, and allow instant full-light output compared to mercury lamps.

Q:Can a single wavelength eliminate all bacteria?

Yes, a single wavelength can be used, though different bacteria have slightly different optimal absorption wavelengths around 265nm.
