Outdoor lighting installation cost depends on fixture count, wiring complexity, and whether it's low-voltage or line-voltage — all worth having spelled out.
What to look for
- Fixture brand and count, not just "outdoor lighting package."
- Low-voltage versus line-voltage — low-voltage is generally safer and cheaper to install for landscape lighting.
- Transformer sizing matched to the total fixture load.
- Timer or smart control included, and warranty on both fixtures and labor.
