Landscape Lighting Cables & Connectors

Landscape Lighting Cables & Connectors link your outdoor fixtures to safe, reliable power, delivering clean, low‑voltage energy across yards, walkways, patios, and driveways. Quality cable reduces voltage drop, keeps path lights and spotlights bright and consistent, and stands up to moisture, soil, and UV exposure. Look for direct‑burial, UV‑resistant jackets and oxygen‑free copper conductors; stranded 12/2, 14/2, and 16/2 landscape lighting cable are the most common choices. Use thicker 12/2 for long runs or higher wattage loads, and 14/2 or 16/2 for shorter branches with fewer fixtures.

Connectors matter as much as wire. Choose waterproof, gel‑filled, heat‑shrink, or clamp/pierce connectors rated for outdoor, low‑voltage use. Corrosion‑resistant brass or stainless hardware, silicone O‑rings, and IP67 or better ratings help keep connections tight and dry. Quick‑connects speed installation; gel‑filled wire nuts and heat‑shrink butt splices are excellent for permanent splices and repairs.

Plan your low‑voltage landscape lighting system: calculate total fixture wattage, size the transformer, and select cable gauge to keep voltage drop under 10%. Map runs, use the hub method for even brightness, and leave slack for future fixtures. Bury cable 6–12 inches, use conduit under hardscape, and label junctions. Always power the transformer from a GFCI‑protected outlet and verify polarity.

Seasonally check connections, tighten set screws, and re‑apply dielectric grease. Inspect for nicks from gardening tools and reseal with heat‑shrink. A clamp meter or multimeter helps diagnose dim lights and confirm voltage at the farthest fixture.

Whether you’re lighting a garden path, uplighting trees, or defining a pool deck, choosing the right landscape lighting cable and connectors improves brightness, longevity, and safety while simplifying installation. Shop outdoor low‑voltage cable, direct‑burial wire, and waterproof connectors from trusted, UL‑listed brands to build a reliable, expandable system that looks great night after night. Use tinned copper for coastal sites to resist corrosion better.
