Example Plan for Garden Lighting Design

Here's some example plans for outdoor lighting cables, connectors, light fittings and transformer calculations. Based on a real garden lighting project and design that we helped to realise.

This example is intended to help inspire you to plan your garden lighting design with our safe low voltage 12v outdoor lighting systems.

It is best to begin with a basic layout plan of your garden and landscape features, include dimensions and indicate where you would like the garden lights to be positioned.

Don't worry if you are not sure what lights are best to choose or where they should be positioned. We are here to help you select the ideal fitting to suit your design and budget.

Simple Garden Layout Plan

The example plan shown here is based on the original idea of a client of ours. Transforming a new build garden to create an ideal outdoor space unique and tailored to our client’s lifestyle. We have reproduced the basic information from the original request for clarity.

This low maintenance formal garden encompasses a main patio area with a retaining oak sleeper bed for planting. Steps lead up to the lawn. A curved patio creates additional space where a raised oak sleeper bed and corner feature are ideal for planting a selection of smaller trees. The upper level area draws the eye and creates visual interest from the main patio.

The garden area is approximately 148 m2 and outdoor lighting was intended for safety and to create an atmospheric vibrancy by illuminating the borders and features.

Outdoor Wall Lights provide up-down lighting for safety and visual effect. Decking lights recessed into sleepers are ideal for indicative lighting along the main patio. Small spotlights placed between smaller trees and diagonal illumination creates shadowing effects on the garden wall. Spotlighting the tree from the ground up creates a dramatic lighting effect that unhides the corner feature at night.

In this design all the light fittings are safely connected and powered from a low voltage outdoor lighting transformer. They all needed to be driven using safe 12v cables and low energy consuming LED bulbs.

We know from the sketch the location of the 12v transformer, the relevant dimensions of the garden and the number of fittings the client has requested.

It's now time to calculate the cables required.

Example Garden Design Layout Plan

Cable Runs and Connectors

In this lighting plan the 12v transformer is shown at the bottom near the main patio and is marked '230v main supply socket'. The HUB 50 - 12v Transformer (transforms mains 230v to safe 12v) - 50w maximum power output. The transformer has 2 cable outlets that are used to feed two separate cable runs (circuits). One cable run is required in this plan and all light fittings have their own cable with a mini connector that simply fits to an Easy-Lock connector at points along the cable run.

The Cable Run for Lights

The overall cable run is approximately 38 metres so we have chosen to use the 40m Cable.

The cable runs starts at the main patio planting bed with 1 FUSION 22 RVS or 1 HYVE 22 RVS connected.

The cable runs along the main patio planting bed and raised sleeper bed to connect 7 x HYVE 22 RVS or 6 x FUSION 22 RVS lights recessed within the sleeper steps and raised sleepers for indicative lighting along the main patio.

The cable run continues into the planting bed on the left hand side of the garden (upper level). At this location we use the Twin Cable Connector to create a cable branch run for the 2 x ACE UP-DOWN 12v Wall Lights. In this lighting plan one cable branch run is required to connect the two 12v wall lights.

The main cable run continues up the left hand side of the garden through the gravel trap that runs adjacent to the upper patio area and the cable runs through the raised sleeper bed. Here positioned between smaller plants are three MINI SCOPE 12v Spotlights are easy to install with ground spike included.

The cable run finishes at the corner feature where a SCOPE 12v Outdoor Spotlight is connected.

The End of the Cable Run

The end of the cable run is secured with a twin cable cap attached.

Transformer Calculations

For readability we have also produced the graphic illustrated. This shows the wiring layout, products and transformer calculations.

Bear in mind that the customer also has a 2 metre lead on each spotlight so the final positioning around plants and shrubs etc can be decided when the lights are installed.

There are eleven Arcus spotlights (shown as circled 'A's on the diagram).

Each spotlight has a 5 watt LED so in total 55 watts (25w on the left hand cable run and 30w on the right hand cable run).

In addition, the five Brevus decking lights on the left hand cable use 1w each; so 5w in total.

Finally, the three Lapis pond lights on the left hand cable use 3w each; so 9w in total

Adding all lights (Arcus, Brevus and Lapis) gives a total energy use of 69 watts.

A 60w transformer would not have enough power to light-up all the bulbs so in this example you would choose a 150w transformer.

Professional Designs

Finally, if your having a professional designer to layout your new garden, do make sure your design covers the lighting needs from the outset. It's easier to build-in good lighting from the start rather than add it later!

If you're having a garden or building design created then we can add value to your design by overlaying our low voltage lighting design.
