I wanted to put a light in my loft with a switch so i was just going to tap into one of the roses from another room. The thing is the conduit is all metal and so are the roses the one i had a look at had 2 conduit pipes coming out of it one pipe had 2 black wires which were joined and a red wire which went into the other pipe. the second pipe had a white wire and the red wire, i was totally lost, the pendant was connected by connecting the blue to black and brown to white. Could someone please explain to me how i would tap into this wiring to add a light in my loft and a switch. Thanks
