Read a thread a couple weeks back about using Hi Tuff cable for outside lighting. I'm quoting for some outside lights, on a south facing wall. Thinking of using Hi Tuff, but never used it before and only gonna need about 25m, so doubt I'll be able to get it in such small quantity from my wholesalers. Is it called Hi Tuff or NYY-J, or are they the same thing. I'm having trouble sourcing some from reputable on-line supplier (that sells it by the metre).
