Lighting Wire

Lighting wire for dependable low voltage installs. Choose direct-burial, sunlight-resistant copper cable for 12V landscape systems, plus fixture leads and extension whips to finish clean, serviceable runs.

Shop by need

  • Low voltage cable: 12/2, 14/2, 16/2 stranded copper, sunlight and moisture resistant
  • Fixture leads: 18/2 whip extensions and pigtails for path, step, and accent lights
  • Multi-conductor: 4-conductor and 5-conductor for RGB/RGBW or control accessories
  • Jacket options: direct-burial PVC or heavy-duty outdoor-rated jackets
  • Lengths: cut lengths and bulk spools for small jobs or whole-yard runs

Quick choosing guide

  1. Pick the gauge: use heavier wire for longer runs and higher watts. 16/2 for short, light loads; 14/2 for medium runs; 12/2 for long pulls or higher total watts.
  2. Plan the layout: hub or T-splits help limit voltage drop. Aim for about 11–12V at the farthest fixture.
  3. Match the jacket: choose direct-burial, sunlight-resistant cable for permanent outdoor installs.
  4. Allow slack: leave service loops at fixtures and the transformer for maintenance and adjustments.
  5. Follow local code: bury cable to required depth and keep splices above standing water in boxes.

Pro tips: Test voltage at the farthest fixture, label each run at the transformer, and use gel-filled, direct-burial connectors for every splice. Upsize wire on long pulls, route in conduit under hardscape crossings, and keep cable out of mower lines.
