3x1.5 or 5x1.5 NYM in the roof box for LED spots?

I want to lay an electrical cable all around in the roof box to operate LED spots.

What are the advantages and disadvantages of 3 or 5 wires for lighting?

Too much never hurts, but what are you planning to do with the five veins?

Yes, exactly. To turn the light on and off, three are sufficient. Why five?

You actually only need 5 cores for special requests like DMX, Tunable White LED, and the like. For the cable lengths, I would rather think of 2.5mm² than more cores.

Maybe you want to connect a motion detector or twilight switch at some point, so take 5.

Our switch setup:


1) Photocell on the west exterior wall.
2) Two-core control cable from this to a twilight relay in the General Electric fuse box, their circuit breaker.
3) The device's sensitivity can be adjusted by a rotary knob, whether it should switch on already in bright light or almost never or somewhere in between.
4) From it three wires to 5 LEDs at 1.3 watts each in the roof overhang on the main entrance side. It switches them on and off, on at sunset, off at sunrise.
5) They burn all night; 5*1.3 uses virtually no power. Karsten
