Notes for UVB-LED 305nm -310nm

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