ok then, sorry but i had to ask.
you wire all the lights up in paralel , using 1.5mm t & e
at the first light you wire in a dusk / dawn sensor.
(comes with instructions) but basically it wants a premanent supply, and gives a switched live when its dark
the swicthed live is connected to the live of the first light
the neutral is connected to the neutral of the first light.
your incoming supply (via fcu) is conected direct to the sensor (you already have the link there for the neutral
for an override switch you connect a cable across the incoming live and the switched live
all earths should be connected together
it may be an idea to spur off a socket, via an fcu
parts:
1.5 t & e cable
suitable external lights (1000w max for sensor)
clips
1 gang 1 way switch (over ride)
