Help Mounting Outside Light

[chris.tarry85]

Hi All,

I want to mount an outside light on the wall next to our new patio and was planning on tapping in to the lighting circuit in the roof of the adjacent single story building and running down from the soffit board to the light.

There are no suitable sockets or switches on the interior of the ajoining wall to drill through from.

I was planning to use to external trunking like this to make it look neater and also allow me to fit a suitable external switch.

However I am stumped about how to terminate this in to the back of the light itself as most seen desgined for a cable emerging directly from the wall behind the light.

The kind of light I had in mind was something like this:

Does anyone have any suggestions how this might work?

Thanks,
Chris

In past when I encountered this problem with outside lights , you can drill a hole about 12-14mm where the light is going & using a steel fish tape push it up the cavity to the eaves, then attach cable & pulled it down & out.

Might even be able to move a tile, & have enough slack in felt to push it it up a bit, to get to cavity, you could you use cable draw rods & feed down to the hole drill where light will go, & again attach cable & draw out.
This method is usually a bit harder to do.

I'm afraid cavity wall insulation rules out pushing or pulling anything in the cavity, hence the external trunking

depends what type of light you want to use, the one you linked is ideally designed to take a cable coming out of the wall, but if i had to mount it using conduit i would probably run the conduit down the wall to just above the light, or to one side of you like (whatever you think looks best) and wire it in flex and leave slack to form a drip loop below the light and enter from below by making an entry by drilling a shallow notch out of the brickwork at the bottom of the lights base, or you could cut a notch into the metal base to avoid damaging the brickwork.

or you can buy lights with a cable channel in the base, like how wired keyboards had cable routing channels on the bottom surface. so just run conduit to top of light and run flex under base using the channel and then into base through the gland/entry hole, silicon the hole up.

something like this should have the cable channels.

or other light types & security light/floodlight style lights are mounted on a bracket and designed to be entered by flex on the surface rather than from the brickwork.
