12V vs 120V Landscape Lighting: Which Is Best for Your Home?
When it comes to landscape lighting, one of the first decisions you'll face is voltage. Should you choose a low voltage (12V) system or go with line voltage (120V)?
Both options can light up your outdoor space beautifully—but the right choice depends on your goals, budget, and property setup. This post breaks down the key differences so you can confidently invest in the best lighting system for your yard.
What Is Low Voltage (12V) Landscape Lighting?
Low voltage systems use a transformer to reduce your home’s 120V current down to a safer 12 volts. This setup is widely popular for residential outdoor lighting.
Key Features:
-
Safe for DIY installation
-
Energy-efficient and cost-effective
-
Compatible with LED technology
-
Flexible placement for gardens, trees, pathways, and decks
💡 At Gardenreet, all of our low voltage landscape lights run on 12V AC/DC—making them safe and stylish for any yard.
What Is Line Voltage (120V) Landscape Lighting?
Line voltage lighting operates directly from your home’s standard electrical circuit—just like your indoor lights.
Key Features:
-
Requires deep trenching and professional installation
-
Permits longer cable runs with fewer voltage drops
-
Typically used for large commercial spaces or expansive estates
⚠️ Important: Due to safety risks, most cities in the U.S. require a licensed electrician to install 120V outdoor lighting systems.
Low Voltage vs High Voltage: Side-by-Side Comparison
| Feature | 12V Low Voltage | 120V Line Voltage |
| Safety | Safe for DIY and pets/kids | Risk of shock; requires conduit |
| Installation | needs transformer & wiring | needs permits & wiring |
| Energy Use | Lower energy consumption (LED-ready) | Higher energy use |
| Maintenance | Easy bulb/fixture replacement | Harder to repair; expensive parts |
| Cost | Lower upfront & maintenance cost | Higher total cost |
| Best for | Homes, gardens, patios, driveways | Commercial spaces, long runs |
Why Most Homeowners Choose 12V Low Voltage Lighting
For U.S. homeowners, the benefits of 12V lighting systems far outweigh the complexity of 120V setups.
-
Lower installation cost
-
Safe and flexible—great for tree uplighting, driveway markers, or pathway lights
-
Energy-saving when paired with LED bulbs
-
Easy to expand or modify without permits

What Experts Say
According to the U.S. Department of Energy, LED lighting is more energy efficient and lasts longer than traditional lighting methods, making it suitable for a variety of outdoor lighting needs.
FAQ
Q1: Is low voltage lighting bright enough?
Yes. With today’s LED technology, 12V systems can deliver just as much brightness as 120V systems, especially for accent lighting.
Q2: Can I install low voltage lights myself?
Absolutely. Most low voltage systems are plug-and-play and don’t require an electrician—just a transformer, cables, and fixtures.
Q3: Will 120V lights save me money in the long run?
Not necessarily. While they can support long-distance wiring, the higher energy consumption and installation costs often outweigh the benefits in residential settings.
Conclusion
For most homes, 12V low voltage landscape lighting is the clear winner—it’s safer, easier to install, and energy-efficient. While 120V systems suit large or commercial spaces, 12V lights offer the ideal balance of performance and flexibility for residential use.
