new outside light

I just used some 3-core flex rated for external use. It had a thicker insulation than normal and a rubbery exterior that was resistant to UV. But as you say, you can get away with TWE most of the time. Simon.

Cheers, where did you buy the flex? TLC dont seem to do it (unless I have missed it)

Normal T&E might deteriorate from exposure to UV light, especially if on a south facing wall but often seems to be used without problems. For something more durable you could use Hituf .

I just got it from B&Q cut off a roll. It said exterior cable, UV safe, I only wanted a short length. If you go to any electical wholesalers, I'm sure they will provide something similar. Simon.

Hi-tuff, on the TLC website.

Thanks to all. The Hi-Tuf might be the way forward! After much deliberation, I think that I will try and do as John says and fit the light in such a position that the cable is fitted into the rear of the fitting and is therefore unseen. However... I may want to add another one or possibly two lights in series off this light so will probably use hi-tuff to do it.

You can use T&E in conduit if you prefer... its what I did on my outside lights - tends to look a bit neater than surface wires clipped on.

If you connect more lights they need to be in parallel not series.

T&E is fine if painted with gloss topcoat to eliminate the slight risk of too much uv damage, but is no longer compliant.
