I was reading somewhere about wiring those outdoor 150W (or 500W!) halogen PIR lights. Different web sites and forums have given different opinions and I am wondering what is right/best?
Since the light is mounted on a bracket away from the wall, it was suggested that T&E should not be used because it is not flexible (OTOH once positioned, will the lamp ever be moved again?). I also rad that T&E is not UV stable.
Another suggestion was to put the T&E in conduit but another web site said that only black conduit is UV stable. Is that true? if white conduit were used would it eventually go brittle, and would it also allow UV through, because if so, that would defeat the object of using it in the first place.
Another forum said the correct cable to use was arctic cable because being outdoors, the temperature can get very cold in winter but I've only ever seen arctic in bright yellow or bright blue. I'm looking for something prettier than black conduit or bright arctic cable!
I know I ought to drill through the wall and run the cable under the floorboards, then I wouldn't need to worry about anything along the outside of the house, but that means making sure I drill at the right height into the floor void and not through the wallpaper of the room above or below! It also means having to move furniture and carpets to lift boards etc, which is a bit of a hassle.
TLC sell hituf, which claims to be UV resistant but is there anything special in it to make it so, or is all black PVC UV resistant by design? After all, aren't coax and external telephone cables black too? Would any old black flex do?
