Hi. I recently moved into my house and had to turn the power off to do one or two jobs. Then after I turned the power back on I noticed that my outdoor security light wouldn't go off, even after leaving it for two days. It has a motion sensor and also a photo sensor, but moving the controls for these doesn't seem to do anything. Does anyone have any ideas about how I can get it to switch off? It seems to be connected to the ring main for all the other lights downstairs, so switching it off at the fuse box isn't an option!!
