On 22^st December 2017, Qingdao Jason Electric Ltd Co. announced that they have successfully demonstrated a 3 Watt high output power 275nm UV-C LEDs lamp, which is only after few months with their recent success on the 1 watt UVC LEDs Lamp development. In order to fulfill a large amount of requests for high power UVC LEDs lamp from the industry of water and air purification, Qingdao Jason has continued to put efforts on research of such high power UVC LEDs lamps. Today’s achievement is another big step forward. The 275nm UVC lamp was measured for optical power using calibrated integrated sphere，the total optical power of 3 Watt was measured at 3.6 A dc operation, the lifetime of the lamp is estimated to be about 5000 hrs. The current-power characteristic graph is shown in figure 1.
