taken down a 3 bulb ceiling light, replaced with a single basic ceiling rose.
when I took down old one there were 4 red wires and 4 black ones, although 1 black wasnt connected to anything.
I have put it all back up, all 4 red going to the live brown(in rose) and 3 black going to neutral blue (in rose).
The light comes on but the dimmer isnt working and it also isnt going off.
Any ideas please?
