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 UVLEDs: Class 1 Static Electricity These LEDs are sensitive to electrostatic discharge (ESD). 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. Operation Do only operate these 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. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice www.roithner-laser.com 3
