Principles of UVC Disinfection: Break the DNA Structures:

UVC Disinfectant LED




Do not touch the LED, or will affect the normal light-emitting devices
Power devices must confirm the positive and negative, reversing polarity may damage the device
Strictly operate in accordance with electrical parameters, too high voltage may damage the device
UVC-LED status should be avoided close observation with the naked eye.
