Precautions against ESD must be taken when handling or operating these LEDs. Surge voltage or electrostatic discharge can result in complete failure of the device. UV-Radiation: During operation these LEDs do emit high intensity ultraviolet light, which is hazardous to skin and eyes, and may cause cancer. Do avoid exposure to the emitted UV light. Protective glasses are recommended. It is further advised to attach a warning label on products/systems that do utilize UV-LEDs: Class 1 Operation: Do only operate LEDs with a current source. Running these LEDs from a voltage source will result in complete failure of the device. Current of a LED is an exponential function of the voltage across it.
