Planning Your Landscape Lighting

Before you start installing landscape lighting, plan carefully. Thoughtful planning ensures that your lighting looks great and functions well. Here’s how to get started:

Layout and Design

First, sketch a layout of your yard. Identify the areas you want to illuminate, such as pathways, trees, or garden features. Use a flashlight at night to experiment with different lighting styles. This will help you decide whether you need spotlights, floodlights, or path lights.

  • Spotlights: Highlight specific features like statues or trees.
  • Floodlights: Illuminate large areas such as driveways or patios.
  • Path Lights: Ensure safe walking paths and add a decorative touch.

Transformer Size

The transformer is crucial for low voltage lighting. It converts your home’s 120-volt current to a safer 12 volts. Choose a transformer that can handle the total wattage of all your lights. For example, if you have 10 lights at 20 watts each, you’ll need a transformer that supports at least 200 watts. Consider buying a larger transformer if you plan to add more lights later.

Light Placement

Proper light placement is key to a successful installation. Here are some tips:

  • Path Lights: Place them about 10 feet apart to ensure even coverage.
  • Spotlights: Position them at the base of trees or features, angled upwards.
  • Floodlights: Mount them higher, like on walls or poles, to cover larger areas.

Avoid placing lights where they will be easily damaged by lawnmowers or snow shovels. Always check for underground utilities before digging by calling 811.

Seasonal Factors

Think about how the seasons will affect your lighting. Some plants may block lights in the summer but not in the winter. Also, consider placing lights where they won’t be damaged by snow or ice. For example, hydrangeas and dogwoods look stunning when lit up, even without leaves.

Safety Precautions

Safety should always come first. Here are some key precautions:

  • Turn Off Power: Always turn off the main circuit breaker before working with electricity.
  • Check for Underground Utilities: Call 811 to avoid hitting any underground wires or pipes.
  • Use Weatherproof Connectors: Ensure all wire connections are weatherproof to prevent electrical hazards.
  • GFCI Outlets: Use Ground Fault Circuit Interrupter (GFCI) outlets for all outdoor electrical connections.

Planning your landscape lighting carefully will save you time and effort in the long run. Next, we’ll dive into choosing the right equipment for your project.

Choosing Your Lighting Equipment

When installing landscape lighting, picking the right equipment is crucial. Here’s a breakdown of what you need to know.

Low Voltage vs. Line Voltage

Low Voltage (12V): This is the most common choice for DIY landscape lighting. It’s safer and easier to install. You only need a transformer to step down the voltage from your house’s 120V to 12V.

Line Voltage (120V): This type requires a licensed electrician for installation. It’s used for more robust lighting needs but can be more dangerous and complex to set up.


Transformers convert your home’s 120V current to a safer 12V for your lights.

Choosing the Right Transformer:
1. Calculate Wattage: Add up the total wattage of your lights. For example, if you have 10 lights at 20 watts each, you’ll need a transformer that can handle at least 200 watts.
2. Extra Capacity: Multiply the total wattage by 1.25 to ensure you have extra capacity (e.g., 200 watts x 1.25 = 250 watts).
3. Future-Proofing: Consider getting a larger transformer if you plan to add more lights later. If you need 400 watts now, a 600-watt transformer gives you room to grow.

Types of Lights

Spotlights: These are ideal for highlighting specific features like trees or sculptures. They offer a focused beam.

Path Lights: Perfect for illuminating walkways and garden paths. They usually have a broader, softer light.

Wire Gauge

Choosing the right wire gauge ensures your lights get the right amount of power.

  • 10-Gauge Wire: Use this for the main lines from the transformer to where the lights begin.
  • 12-Gauge Wire: Use this between lights. It’s thinner but still efficient for short distances.
  • 14-Gauge Wire: Suitable for smaller systems or shorter distances.

Weatherproof Connectors

Use weatherproof connectors to ensure your connections are safe from the elements. These connectors have a sealant inside to keep moisture out.

Tools Required

Having the right tools will make your installation smoother:

  • Wire Strippers: Essential for stripping the insulation off your wires.
  • Flat-Nosed Shovel: Useful for digging trenches to bury your cables.
  • Electrical Tape: For securing wire connections.
  • Siding Clips: To attach wires neatly along walls or fences.

Example Case Study

John’s Garden: John wanted to light up his garden path and highlight a few trees. He used:

  • A 300-watt transformer
  • 6 spotlights (20 watts each)
  • 4 path lights (10 watts each)
  • 100 feet of 10-gauge wire for the main line
  • 50 feet of 12-gauge wire between lights
  • Weatherproof connectors

John followed the calculations and guidelines to choose his equipment, ensuring a successful and safe installation.

By carefully selecting your lighting equipment, you can create a stunning and functional outdoor space. Next, we’ll walk you through the installation steps.

Installation Steps

Marking and Preparing the Site

Cable Laying: Start by laying out your low-voltage cable along the planned path. This helps you visualize the layout and ensures you have enough cable.

Trench Digging: Use a shovel or trenching tool to dig a trench about 6 inches deep. This depth is typical for low-voltage cables but check local codes to be sure.

Sod Removal: If your cable runs through a lawn, remove the sod first. Slide a flat-blade shovel under the grass, lift it, and fold it back. This makes it easier to lay the cable and minimizes lawn damage.

Obstacle Management: When you encounter obstacles like rocks or roots, either go around them or dig under them. This ensures your cable stays protected and out of sight.

Setting Up the Transformer

Transformer Location: Choose a spot near a GFCI outlet. The transformer needs at least 1 foot of clearance on all sides and should be at least 30 feet away from water features.

GFCI Outlet: Plug the transformer into a GFCI outlet. This type of outlet protects against electrical shock.

Weatherproof Cover: Use a weatherproof cover for the outlet. This keeps the connection safe from rain and moisture.

Voltage Settings: Connect the wires to the transformer. Use the 12-volt tap for shorter runs and the 15-volt tap for longer runs that draw more power.

Installing the Lights

Fixture Assembly: Unpack and assemble your fixtures. This usually involves installing bulbs and attaching mounts.

Stake Mounting: For stake-mounted fixtures, attach the stakes and push them into the ground where you’ve planned.

Surface Mounting: If mounting on a hard surface, use a power drill to secure the fixtures.

In-ground Mounting: For in-ground fixtures, dig holes and place the fixtures directly into the earth.

Wire Connections: Connect the lead wires from each fixture to the main cable. Use twist-on connectors or clamp connect junctions for a secure connection.

Weatherproofing: Ensure all connections are protected from moisture. This helps prevent corrosion and keeps your system running smoothly.

Testing and Adjusting

Voltage Testing: Turn on your transformer and check each fixture. If a light doesn’t turn on, recheck the connections.

Light Positioning: Wait until nighttime to adjust your lights. Walk around and make sure each light is aimed correctly.

Glare Management: Adjust angles and use glare guards to minimize glare. This ensures your lights enhance your landscape without blinding anyone.

Nighttime Adjustment: Make final tweaks to the position and angle of your lights. This is the best time to see the true effect of your landscape lighting.

By following these steps, you’ll have a beautifully lit outdoor space in no time. Next, we’ll cover maintenance and troubleshooting to keep your lighting system in top shape.
