Landscape lighting designed well can have a transformative effect on your outdoor space at night-time. It can be daunting wondering where to start your lighting project as the possibilities are endless & that is where South Island Electrical can help.  We can guide you from design including lighting techniques & product selection right through to completed installation.


Landscape Lighting Techniques 

Different landscape lighting techniques can be used to accentuate different features of the garden.  A combination of techniques might be used to get the best from your design.

Shadow Lighting
Light & shadow against walls can create a visually eye-catching effect.

This technique can be used to add depth to architectural features, brick or stonework of a building.

Wall-Wash Lighting
This technique creates a subtle, low level of light to a wide area, up close to the structure, with minimal density.

Directing the eye to the textures, this technique highlights height & shape differences in plant beds adding ambiance.

Hardscape Lighting
Highlight features such as benches, retaining walls, steps, or outdoor kitchens.

In-Ground Lighting
Bring light to permanent or semi-permanent installations such as large trees, walls or pathways.

Silhouette Lighting
Give attention to an interesting shape by lighting a vertical surface behind it to accent that shape.


Pathways & Garden Edges

Lighting up pathways & garden edges is functional as well as appealing.  It makes navigating your outside space aesthetically more pleasing as well as safer. Consider deck & patio lighting as well as path lighting in your design.

Water & Leaves

Beautiful calming effects can be created using light through water or leaves.

Mirror Lighting
Strategically lighting background areas around bodies of water that then reflect the landscape off the water.

Underwater Lighting
Enhance & highlight flowing water in streams, waterfalls & fountains to create an enchanted mirroring effect on still waters.

Moon Lighting
Mounting a light fitting high in a tree can catch details of branches & leaves, imitating moonlight.

Low Voltage 12V / 24V & Mains Voltage Options

Landscape light fixtures are typically available in either low voltage (12 or 24 volt) & mains voltage 220 volt.

In general, low voltage light fixtures are less expensive to purchase & easier to install.  They do still need an electrician to install the transformer/power supply. The cable can be buried in the garden without the need for conduit (however this is still recommended to avoid future damage with a spade).

Mains voltage power cables need to be buried in conduit to a depth of 600mm & all connections in sealed junction boxes by a registered electrician.

Low Voltage Fixtures:

  • Easy to install
  • Less expensive to purchase
  • Cable does not need to be in conduit (however recommended)
  • Wide range of options available
  • Safe around water

Mains Voltage Fixtures:

  • Can be more expensive than low voltage options & must be installed by electrician
  • Lower range of options available
  • Not to be used in or around water
  • No need to use transformers
  • Easier installation of wall spotlights where hiding transformers can be difficult
  • You don’t need to be concerned about voltage drop in 240 volt cables as you do at 12 volt
  • Up lighting of large trees often requires use of energy efficient fittings which run at 240 volts
