Outdoor wall lights

[magico]

Hi all, wanting to put external wall lighting on rear and side of my house. Currently have a switched fcu for a outdoor floodlight so planning on swapping this for a alexa switch to run 3 lights on rear and 3 on side of property for trips to bin at night time ect.... I don't really want to use external conduit between each light to daisy link, what's the other best option.... I'm guessing running cable horizontal in cavity is a major task
Cheers

In the main, we use black round cable, as black resists UV better, and round seals better in stuffing glands, and we arrange the cable with loops so water will drip off the cable, not follow it will capillary action into the fitting, and we realise water will always get in to a small extent, so ensure there is a drain at the bottom, even if this is just a gap in the seal.

Example of drip loop.

If we use PIR's then any smart switch must have a neutral or batteries, I use TP-Link (Tapo) smart switches which are battery powered and have dusk and dawn features. I did use Energenie (MiHome) both don't need a neutral, but the latter needs a 5 watt minimum load where the Tapo has no minimum load.

Running cables in the cavity is a no no

If the original power comes from anything other than a lighting circujit you will need to keep that FCU. It is a double pole isolation switch (essential for outside lighting) and it will have a fuse of not more than 5amp - needed for the thinner cables used for lighting wiring.
What "Alexa Switch" do you have in mind? It needs to go after the FCU, not instead of....

With ya Taylor, didn't think of that. So forget the alexa switch unless they do a fcu 1 hhhmmm. I'll have a look but probably not. Would prefer alexa because they switch is near patio doors in front room and kitchens at the side of the house
Decided to clad the wall half way all way round so cable can go behind cladding between battens, problem solved.

Just buy a “smart” light switch that can be controlled by Alexa. There’s heaps around.

Depending upon building layout - usually through loft, then outside/down works best.

Cables run in cavity, is frowned upon.
