By choosing the right lights and wiring them correctly, you can bring out the best in your outdoor space, and Vergel Irrigation Limited is here to guide you through every step.Types of Landscape Lighting Systems
There are two primary types of landscape lighting systems: low voltage and line voltage. Each system has its own wiring requirements.This system is the most popular choice for DIY enthusiasts because it’s safe and easy to install. It uses a transformer to reduce your home’s standard 120V electrical current to a safe 12V. This voltage is ideal for accent lighting, pathway lights, and garden highlights.
These systems use the same voltage as the rest of your home’s electrical appliances. They are typically used for floodlights or high-intensity lighting, but installation requires professional assistance because of safety concerns and building code compliance.
For most homeowners looking for a safe, energy-efficient solution, low voltage landscape lighting is the best option. In this guide, we’ll focus on wiring a low voltage system.Tools and Materials You’ll Need
Before you start the wiring process, make sure you have the right tools and materials. Here’s what you’ll need:Step-by-Step Guide to Wiring Landscape Lighting

Begin by sketching out a layout of where you want to place your lights. Consider both functionality and aesthetics—lighting walkways for safety, illuminating garden beds, and highlighting architectural features.
Once you have a plan, measure the distance between each light and the transformer. This will help you determine how much wire you’ll need. Keep in mind that low voltage systems lose power over long distances, so make sure to place your transformer relatively close to the lights.
The transformer converts your home’s 120V electricity to 12V for your lights. To select the correct transformer, calculate the total wattage of your lights by adding up the wattage of each fixture. Your transformer’s capacity should exceed this total wattage to ensure it can handle the load.
For example, if you have ten 5-watt lights, you’ll need a transformer with at least a 60-watt capacity. Vergel Irrigation Limited offers a wide range of low voltage transformers, some with built-in photocells that automatically turn your lights on at dusk and off at dawn.
Start by placing your transformer near a GFCI outlet.
Unroll the low voltage wire from the transformer to each light fixture location, leaving extra wire at each fixture point for connections.
Use a shovel to dig a shallow trench (about 3-6 inches deep) for burying the wire. This keeps the cable protected from damage.
Make sure to run the wire in a way that minimizes the distance from the transformer to avoid voltage drop.Cut the wire where each fixture will be installed, leaving enough slack to make a secure connection.
Strip about ½ inch of insulation from the wire ends.
Attach the fixture's leads to the cable using the quick-connect fittings or wire connectors. Ensure the connections are tight and secure.
Wrap the connections in electrical tape to protect them from moisture and dirt.
At Vergel Irrigation Limited, our landscape lights are designed for easy installation, with durable quick-connect fittings to make the process hassle-free.
Mount the transformer on a wall or post near your GFCI outlet. Make sure it’s placed in a location that’s easy to access for maintenance or adjustments.
Attach the two leads from the low voltage cable to the transformer’s output terminals.
Plug the transformer into the GFCI outlet.
If your transformer has a built-in timer or photocell, you can set it to automatically turn the lights on and off based on the time of day or ambient light levels.Before burying the wire, test your lighting system to ensure everything works as it should. Turn on the transformer and check each light to make sure it’s properly illuminated.
If some lights appear dimmer than others, this could be due to voltage drop. Use a voltmeter to check the voltage at each fixture; it should be between 10.5V and 12V. If the voltage is too low, you may need to use a thicker gauge wire or shorten the distance between the transformer and the farthest light.
Once you’re satisfied with the placement and brightness of your lights, it’s time to bury the wire in the trench. Make sure the wire is fully covered to protect it from damage caused by lawn maintenance or weather conditions.
If your transformer includes a timer or photocell, now is the time to set it. A timer allows you to control when the lights turn on and off, while a photocell automatically adjusts the lighting based on natural light levels.
At Vergel Irrigation Limited, we offer transformers with built-in timers and photocells for effortless automation, so you never have to worry about manually turning your lights on or off.
