Are you looking to create an enchanting ambiance in your garden? Look no further than low voltage LED garden lights. These lights not only illuminate your outdoor space but also offer energy efficiency and versatility. In this article, we'll delve into the details of low voltage cabling layout for LED garden lights and provide some useful tips for a successful installation.
How Does Low Voltage Cabling Work?
Most LED garden lighting operates at 12 volts, which requires the use of transformers or DC power supplies in your garden. To connect the lights to the power source, you'll need flexible low voltage cable. It's important to note that the cable loses voltage based on its length and the number of lights connected to it. However, with LED garden lighting, this is rarely an issue as they consume much less power than traditional halogen lights.
To optimize the performance of your garden lights, it's a good practice to keep low voltage cable runs as short as possible. This ensures that the lights receive sufficient voltage to shine brightly. When selecting a cable, opt for a round, double-insulated rubber type with a tough outer sheath. This type of cable is resistant to moisture and salts in the soil, making it ideal for most garden lighting applications.

The Importance of Cable Protection
To avoid any damage to the cable, it's recommended to run it under bark or gravel mulch. This not only aids flexibility in locating the garden lights but also protects the cable from external elements. Additionally, consider using protective conduit in areas where the cable might be vulnerable, such as under a grass path where lawn edging could potentially damage it.
For a neat and secure installation, use black clips to clip the cable over pergolas and along deck joists. This minimizes the chances of accidental damage caused by gardening activities, children's games, or animal nesting.

Choosing the Right Cable Size
In most cases, you won't need the thicker 4mm2 cable to overcome voltage drop for LED lights. As a standard, we recommend two sizes of ground burial low voltage cable:
- 2.5mm2 (T9912 - 50m; T9913 - 25m): Ideal for longer cable runs and higher power LED lights.
- 1.5mm2 (T9918 - 50m): Suitable for low power applications, such as wiring up LED lights around a deck.
By selecting the appropriate cable size, you can ensure efficient power transfer and prevent any drop in light output.
Frequently Asked Questions
Q: What length of cable can I use from the power supply to a garden light?
In a 12-volt garden lighting system, it's crucial to limit "cable voltage drop" to maintain optimal light output. The table below provides the maximum cable run length for typical garden lighting wiring requirements. For LED lights, which consume less power and are less sensitive to voltage reductions, longer cable runs are possible.
Q: How should I handle power supply location and low voltage cabling?
- Place the power supply centrally among the group of garden lights it will power.
- When operating multiple sets of garden lights with separate switches, use separate power supplies and circuits.
- If the cable run exceeds the recommended maximum length for a single garden light, revise the layout by either increasing the number of power supplies or using thicker cable.
- For multiple lights connected to one cable, ensure the cable run is within the recommended maximum length by dividing the LED garden lights onto individual cables.
Remember, always exercise caution when working with electrical installations and, if needed, consult a qualified electrician.
