I’d like to put some lighting at the back of the garden.
I’ve got a load of questions, but really after general advice and things to consider / watch out for.
I’m thinking 12V rather than mains since I might be able to DIY 12V; and anyway there’s a tiled patio to get past from the house which I believe mains would need to be buried under.
My plan at the moment would be to DIY the fitting of the lights and the wiring back to the house wall; doing a test connection to the transformer plugged into a mains socket. Then get an electrician to wire up the transformer to the lighting circuit.
I plan to use around 4 MR16 LEDs, with scope to add more later if that’s not enough light (so maybe allow for 50W), mounted high in a gazebo and a tree.
I’d bring the cable back to the house along our garden fence. This has some planting in front of it in places so the cable won’t look bad. What sort of cable should I use? 1.5mm 2 core SWA? Or should I put regular cable in a conduit; and if so what conduit? And then, what sort of junction boxes should I use? Something like https://www.tlc-direct.co.uk/Products/WK108B.html ?
If I get a transformer like http://www.ledcentre.uk.com/238-12v-transformers-led-power-supplies/179-led-transformer-/-power-supply-60w-12v-dc-5.0a-waterproof.html I assume I just mount it to the wall.
Thanks in advance for any help!
