About this calculator
Landscape lighting cost combines fixture costs, wire installation, labor for each fixture, and a fixed transformer/base fee. The formula is: Cost = ((pathLights × 65 + spotlights × 95) × lightingType) + (wireDistance × 3.5) + ((pathLights + spotlights) × installComplexity) + 350. Path lights are priced at a base of $65 each and spotlights at $95 each — reflecting typical mid-grade fixture costs — then multiplied by a lighting-type factor that scales up for premium or smart-home systems versus basic low-voltage kits. Wire installation is charged at $3.50 per foot of cable run, covering conduit, connectors, and burial labor. Each fixture also carries a per-unit installation complexity charge (e.g., harder soil, decorative mounting). The fixed $350 covers the transformer, a timer/photocell, and system setup — costs present on virtually every professional low-voltage installation regardless of fixture count.
How to use
Example: 6 path lights, 4 spotlights, standard low-voltage system (lightingType = 1.0), 120 ft wire run, moderate complexity (installComplexity = 25). Step 1 — fixtures: (6 × 65 + 4 × 95) × 1.0 = (390 + 380) = $770. Step 2 — wiring: 120 × 3.5 = $420. Step 3 — install labor: (6 + 4) × 25 = $250. Step 4 — base fee: $350. Total = 770 + 420 + 250 + 350 = $1,790. Upgrading to a smart LED system (lightingType = 1.4) raises the fixture term to $1,078, pushing the total to $2,098.
Frequently asked questions
How much does professional landscape lighting installation cost on average?
Most homeowners spend between $1,500 and $4,500 for a professionally installed low-voltage landscape lighting system, with the wide range driven by fixture count, system type, and yard size. A modest system with 8–12 lights and short wire runs typically lands around $1,500–$2,500. Large properties with 20+ fixtures, long cable runs, smart-home integration, or extensive spotlighting for trees and architectural features can exceed $5,000. Getting an itemized quote from a licensed electrician or landscape contractor is the best way to validate these estimates.
What is the difference between low-voltage and line-voltage landscape lighting?
Low-voltage systems (12V) are the standard for residential landscape lighting because they are safer to install, energy-efficient, and compatible with LED bulbs. They run off a transformer plugged into a standard outlet and are suitable for path lights, spotlights, and accent fixtures throughout the yard. Line-voltage systems (120V) deliver brighter output and are better for large commercial areas or security lighting, but require a licensed electrician for installation and carry higher operating costs. Most homeowners use low-voltage LED systems for their combination of safety, longevity, and energy savings.
How far apart should landscape path lights be placed?
Path lights are typically spaced 6–10 feet apart for functional illumination that guides walkers without creating harsh bright spots. Spacing depends on the fixture's beam spread and lumen output — brighter fixtures can be placed farther apart, while subtle, decorative lights work best closer together. For a 40-foot walkway, plan on 5–7 fixtures to achieve consistent, overlapping pools of light. Wider spacing saves on fixture and wire costs but can leave dark gaps, while tighter spacing creates a more polished, resort-style look.
