Lighting circuits are wired in two different ways, using either junction-boxes or loop-in ceiling roses. These days, the loop-in system predominates - though individual circuits often combine the two for the most economical use of cable.
Unlike power circuits, lighting circuits are always of the radial type: the cable leaves the consumer unit and runs to each outlet position before terminating at the last fitting on the line. Most houses have at least two lighting circuits - usually one upstairs and one down.
