Everything homeowners need to know before installing their own landscape lighting—from transformers to fixture types and common pitfalls.
DIY Landscape Lighting: Common Questions Answered
Thinking about installing your own landscape lighting? You're not alone! Many homeowners are taking lighting into their own hands (literally) to boost curb appeal, improve safety, and enjoy their yards and patios at night.
To help you get started, here are answers to the most common DIY landscape lighting questions—broken down by topic for easy reading.
⚡ Power & Electrical Basics
Do I need a transformer?
Yes. Most landscape lighting uses low-voltage (12V) power, so you’ll need a transformer to step down from standard 120V household power. These transformers convert your 120V to a safe low-voltage of only 12V, saving you money while your lights are running.
How many lights can I connect to one transformer?
It depends on the wattage of your transformer and your fixtures. Add up the total wattage of your lights and leave a 20% safety buffer.
The Math:
It you have 20 2-watt lights, that equals 40-Watts total, so you would need at least a 48W transformer when you include your 20% buffer.
| 20 x 2W = 40W | 40W x 20% buffer = 48W |
Can I plug my lights into an outdoor outlet?
YES, but... your lights will never be plugged DIRECTLY in to an outlet, they must be connected to your Low-voltage transformer. The transformer is designed to plug into a GFCI-protected outdoor outlet, at standard 120V line voltage, and "transform" or step-down the voltage to the required 12V range.
What’s the difference between 12V and 120V lighting?
> 12V (low voltage) is safer, easier to install, and ideal for DIY projects.
> 120V (line voltage) is used in commercial setups and typically requires conduit and permits. 120V is what most of your home runs on. Any normal outlet you see around your house, inside and out, is probably 120 volts.
🛠️ Installation Questions
Landscape Lighting wire gets buried to be out of sight and protected. But how deep should I bury the wire?
> For low-voltage systems: 6 inches into the ground is usually enough. Take precautions if you live in an area with a lot of underground pests though.
> For line-voltage systems: 18 inches with conduit (check local electrical codes).
How far apart should lights be placed?
> Path lights: 5–8 feet apart
> Spotlights: Depends on what you’re illuminating. Spotlights are often used to illuminate specific features or elements of your landscape, such as big trees or fountains.
> Wash lights: About 6–8 feet for smooth coverage of walls, architecture and back drops.
Do I need waterproof connectors?
Yes. Always use waterproof, gel-filled, or heat-shrink connectors to protect wiring from moisture and corrosion. Find them at All Lighting Direct!
💡 Choosing Fixtures & Design
What type of lights should I use?
> Pathways: Use path lights, bollard lights or in-ground lights
> Trees: Uplights, Accents or Well lights
> Walls or fences: Flood or Wash lights
> Steps or decks: Step lights, deck lights, strip lights, in-ground or recessed.
How do I avoid glare?
Aim fixtures downward or use glare shields such as hexcell louvers and frost lens. Avoid placing lights directly in line with where people will look or walk.
Should I use LED bulbs?
Yes! LED lights are energy-efficient, long-lasting, and come in a variety of color temperatures—from warm and cozy to bright and cool. LEDs are considered very safe and cost effective and the top choice for most lighting applications.
🧠 Planning & Troubleshooting Lighting Plans
Can I really do this myself?
Definitely. Low-voltage landscape lighting is designed for homeowners. No electrician required—just some basic tools and planning.
What’s the best lighting layout for my yard?
Focus on:
> Focal points (trees, walkways, architecture)
> Layering (use a mix of light types)
> Balance (symmetry, not necessarily uniformity)
Apps like FX Luminaire’s Luxor service can help too.
Why are some lights dim or not working?
Check for:
> Voltage drop (long wire runs reduce power)
> Loose or corroded connections
> Transformer overload
Should I use timers or smart controls?
Optional, but helpful! Many systems now include:
> Photocells (automatically turn on at dusk and off at dawn)
> Mechanical/digital timers to set and control specific on/off times
> Wi-Fi or Bluetooth smart controls - a great option for homeowners or users want the most control over their landscape lighting.
