Good Day All.

Just a quick stupid question. Here is a guy who wants to install 2 flood lights at his house, but he want to connect it to 3pin plug and plug it into a socket outlet and switch it on only when needed. Now according to the regs, you can feed luminaries from a socket outlet, my question is, with what cable can you run from the 3pin plug to the lights. it is approx 25 - 30 meters? Will normal cabtire work(is it according to the regs the right thing to do) or should it be wired directly from the plug, but via a switch and then mark that circuit as mixed? can you guys please led some light here for me?

thanx
