That is an extremely short length of cable.
Or was that a lapse in your concentration on the accuracy of information in your posts.
Did you mean to say "" Only 1.0mm² is required for lighting "".

Good job to find the '²' on your keyboard ... whats the short cut ...
I'm not an electrician, but wouldn't 1.5mm² guard against any voltage drop, if the run of cable from the CU - to say the second floor was a reasonable distance ...

Apart from asking what voltage drop?
Not as much as it might seem.
Editted - I didn't word it well.
Plus - the CPC is still 1mm².

With the low current taken by modern lighting plus the fact that they continue to operate over a very wide voltage range that would not be a problem.
If it was why stop at 1.5, what about 2.5, 4, or 6?

For the benefit of the op - there are single insulated 'singles', which will be of no use to you.
But 'meter tails' or 'tails' are again single cables, but insulated AND sheathed, which may be of use to you if used correctly.
My reply to this in the Taking it away thread.
ALT 0178
As in hold down ALT and then type 0178 then release ALT

That doesn't work for me...
It only works if you type the '0178' on the numeric keypad, NOT if you use the number keys at the top of the keyboard (and, for information, the '0' at the start is crucial).

Did you type the numbers on your machine's numeric keypad?
As you say, in this forum it's easier to just use the drop-down symbols list, but the ALT-sequences can be used in all sorts of places (like word processors).
Kind Regards, John
They were all done with keypad entry but it feels easier to use the drop down menu, especially as it leaves it on the 'last page'.
Yes, that's a useful and clever (and quite unusual) feature of that drop-down - given that, in any one post I write, it's usual that most of the symbols I use are the same (usually all ² or all Ω).

Yes all the lighting will be LED, so a very small load.
Trying to wire up a lighting loop using roses - with 1.5mm² requires finger tips made of teflon - I guess 1.0mm² would make that task easier, or put all the loop in/out in the back box behind the light switch.
Now knowing where characters such as 'degrees °' etc etc is very helpful.
