Power your outdoor lighting system with Lightkiwi's 12/2 low voltage landscape lighting wire — ETL-listed, pure copper, and rated for direct burial. The 12-gauge, 2-conductor design handles most residential landscape lighting runs with ease, available in 50ft, 100ft, 250ft, and 500ft spools.
Why Choose 12/2 Wire for Landscape Lighting?
12/2 wire is the most popular gauge for residential landscape lighting — thick enough to carry sufficient wattage over long runs, yet flexible enough for easy installation. The "12" refers to the 12 AWG conductor size, and "2" means two conductors (positive and negative). Compared to 14/2 or 16/2, the thicker 12-gauge conductor handles more wattage over longer distances before voltage drop becomes an issue.
How Far Can 12/2 Wire Run?
As a general rule, 12/2 wire supports up to 150–200 watts over 100 feet with minimal voltage drop. For runs beyond 150ft or systems with higher wattage, consider daisy-chaining or using our 10/2 wire for the home run. For lighter loads or shorter distances, 14/2 wire is a cost-effective alternative.
What Makes Lightkiwi 12/2 Wire Different?
Our 12/2 landscape lighting wire is ETL-listed and built with pure copper conductors — not copper-clad aluminum (CCA), which can corrode and degrade over time. The jacket is rated for direct burial without conduit and is sunlight resistant, meaning exposed sections above ground won't crack or degrade from UV exposure.
Frequently Asked Questions
Can I bury 12/2 landscape wire directly in the ground?
Yes. Lightkiwi 12/2 wire is rated for direct burial — no conduit required. Per NEC guidelines, low-voltage wire (under 30V) must be buried at least 6 inches deep.
What is the difference between 12/2 and 14/2 landscape wire?
12/2 has a thicker conductor (lower gauge number = thicker wire), allowing it to carry more wattage over longer distances before voltage drop occurs. 14/2 is lighter and works well for shorter runs or lower-wattage systems.
Is 12/2 wire compatible with all landscape lighting transformers?
Yes. 12/2 wire works with all standard low-voltage landscape lighting transformers (12V systems). It connects directly to the transformer terminals — no adapters needed.
How many lights can I run on 12/2 wire?
It depends on the wattage of each fixture and the run length. As a general guide, keep total wattage under 150W per 100ft run to maintain proper voltage at the fixtures. Use a voltage drop calculator for precise planning on longer or higher-wattage installs.
