The package size Sterilization is 3.45 mm x 3.45 mm x 1.38 mm and the radiant power Medical application typically 3 mW at 20 mA in a wavelength range of 265 nm to 285 nm. Sensing of gases, germs, DNA, ... SAFETY ADVICES PRODUCT GROUP AND PACKAGE DATA Product group: LED These LEDs emit very strong UV radiation during operation. Do not look directly into the LED light when in operation as Package: SMD ceramic UV radiation can harm your eyes. To prevent inadequate Product series: standard power UV LED exposure, wear protective eyewear. If LEDs are embedded Angle of half intensity: 60 in devices, please indicate warning labels. Avoid exposure to skin or other tissue during operation. Keep out of the Lead-finishing: Au reach of children. Take appropriate precautions around pets and other living organisms to avoid UV exposure.
