MY NEW LIGHT BULB THAT SDCPM INSTALLED DOES NOT WORK

Please first install the faulty bulb in another location that you know works with another bulb , to confirm that the bulb is ok 

If it does not work in the other location  , this means that bulb in faulty and you need to install another one that does work , but if it does work then there may be an electrical problem in which case let us know and we will send someone to fix the problem
