Downlights

1.5mm is my personal preference just because i prefere how it terminates, got me thinking now though...

That is why is use it.

Why on earth would anybody use 1.5mm for domestic lighting circuits nowadays, what a waste of money, like using 4mm standard for ring mains

my pet hate!

So what do you use?

There is only a couple of pounds difference between 1mm and 1.5mm where I get my stuff from.

Can't get 1mm T&E this side of the pond in too many places

I haven't used 1.5 T&E for years on domestic.

As far as domestic installs are concerned then 1mm for lighting and 2.5 for small power is almost always the most suitable size.
Generally commercial installs seem to have adopted 2.5mm for lighting and 4.0 for small power as accepted minimum sizes these days, which as a rule of thumb accounts for grouping and VD by default.

That is what I do for commerical. But where I am, 1mm and 1.5mm are pretty much the same price.

What's price got to do with it? 1.0mm is easier to work with, takes up less space in joist holes and fits in to daft decorative light fitting terminal boxes a bit easier

I had never used 1mm twin before I started doing domestic work, never even seen it in fact. I wouldn't even consider using 1.5mm in a domestic install nowadays though. The tiny stuff is so much easier to work with in the horrible customer supplied light fittings I inevitably end up putting them into.

Its not really about the price IMO more about ease of use especially where down lights are concerned.

Welchyboy1's comment is why I mentioned price.

I like the look of that product that Lee has put up, is that it job done or does it need to be in some kind of enclosure, also anybody that does not use 1mm t&e on domestic, don't do many occupied rewires, some of the conduits are tiny on older properties.
