It is 20W, not bright compared any of our streetlight. but it can stand at place like digging etc where always has high temperature. Supposing some flammability gas goes into the bulb, and even the components explode inside, the bulb will keep safe.
Now this model has been chosen to join a tender at our homeland. If everything goes well, we will begin to promote it to our foreign business parners! Looking forward it! ~.~
