Hi need a bit of help. I connected my floodlight to the existing wiring. I used the blue and brown wire and it worked for like 5 seconds and the floodlight just went off. The floodlight had a yellow wire i didnt connect that because the bathroom wiring is a twin 1.5mm and only blue and brown from there was connected. There is a 13a switch for the bathroom so you can use the light in bathroom. And in the bathroom there is a switch for the bathroom light
