Hi, I have a VISUM LED, STRYKER qx light and when I try to turn OFF the lights, one of them DOESN´T TURN OFF. I have to cut all the energy in order to take it off. Is there something I should start lookin for? Also the LED9 on the wall board is on, wich it means that the light 1 defective, but I don´t know what can cause it. Thanks!!
