12/2 Wire

Total Light 12/2 low-voltage landscape lighting wire is a versatile choice for many residential and professional outdoor lighting installations. Designed for direct burial, it connects fixtures to the transformer while supporting dependable power delivery across typical landscape runs. Choose the roll length that fits your project and complete connections with waterproof outdoor-rated connectors.

Why 12/2 Is a Common Landscape Lighting Choice

12/2 direct-burial wire offers a practical balance of conductor size and flexibility for many residential and professional low-voltage landscape-lighting systems. It is commonly used to carry power from the transformer to path lights, uplights, well lights, deck lights, and other compatible 12V fixtures.

Wire gauge should still be selected around the actual project. Longer runs and higher connected loads can increase voltage drop, while shorter and lighter-load runs may have different requirements. Map the system first so the wire choice supports the distance, transformer capacity, and fixture load.

Choose the Roll That Fits the Layout

This collection includes multiple roll lengths and available jacket colors. Measure the real routing path, including branches and fixture-to-fixture connections, and leave workable extra cable at connection points. Use waterproof outdoor-rated connectors for underground splices and follow the transformer and fixture installation instructions.

Frequently Asked Questions

What is 12/2 landscape lighting wire used for?

It is used to connect a low-voltage transformer to compatible outdoor lighting fixtures and is a versatile choice for many typical landscape-lighting installations.

Can 12/2 Total Light wire be buried directly?

Yes. The 12/2 wire in this collection is designed for direct-burial low-voltage landscape-lighting use.

When should I consider 10/2 instead of 12/2?

A heavier 10/2 conductor can be useful when longer distances or larger connected loads make voltage drop a greater concern. The best choice depends on the complete system layout.

How do I choose a roll length?

Measure the intended cable path, including branches, turns, and fixture spacing, then allow extra length for connections and future service. Choose the roll size that covers the planned route without relying only on straight-line distance.
