The cost to install landscape lighting depends on the size of your property, the type of fixtures you choose, and whether the system is hardwired or low-voltage. Landscape lighting adds curb appeal, improves safety, and extends the usability of your outdoor spaces after dark. This guide covers typical costs, what affects pricing, and when to hire a professional.
⚡ Key Takeaways
- No two landscape lighting projects are identical.
- Most homeowners spend between $2,000 and $6,000 for a professionally installed landscape lighting system covering a standard-sized front or backyard.
- The majority of residential landscape lighting systems use low-voltage (12V) wiring, which is safer, easier to install, and less expensive than standard line-voltage systems.
What Affects Landscape Lighting Installation Costs
No two landscape lighting projects are identical. The total price depends on several variables that can push costs up or down significantly. Key factors include:
- Number and type of fixtures (path lights, spotlights, uplights, etc.)
- Whether the system is low-voltage (12V) or line-voltage (120V)
- Size and layout of the area being lit
- Existing outdoor outlets and wiring availability
- Need for underground wiring or trenching
- Local labor rates and permit requirements
Average Cost to Install Landscape Lighting
Most homeowners spend between $2,000 and $6,000 for a professionally installed landscape lighting system covering a standard-sized front or backyard. Smaller projects with fewer fixtures cost less, while large properties with complex designs can exceed $10,000. Here is a general breakdown by fixture type:
- Pathway lights: $75 – $200 per fixture installed
- Spotlights or uplights: $100 – $300 per fixture installed
- Well lights (in-ground): $150 – $400 per fixture installed
- Deck or step lights: $100 – $250 per fixture installed
- Low-voltage transformer: $50 – $300 (higher-wattage units cost more)
- Full system installation (12–20 lights): $1,500 – $5,000
Low-Voltage vs. Line-Voltage Landscape Lighting
The majority of residential landscape lighting systems use low-voltage (12V) wiring, which is safer, easier to install, and less expensive than standard line-voltage systems. Low-voltage systems run off a transformer plugged into an existing outdoor GFCI outlet and are legal for homeowner installation in most areas.
Line-voltage landscape lighting — used for high-powered fixtures, permanent architectural lighting, or commercial applications — requires licensed electrical work and permits. These systems cost more upfront but deliver stronger output and greater durability.
Trenching and Underground Wiring Costs
If your landscape lighting requires underground wiring runs — common for fixtures far from the house or in-ground well lights — trenching adds to the total cost. Expect to pay:
- Trenching labor: $4 – $12 per linear foot
- Conduit materials: $1 – $3 per linear foot
- Backfill and restoration: Included in most quotes or $1 – $5 per foot
A 50-foot underground wiring run might add $250 – $750 to the project total.
Additional Cost Factors
Smart Lighting Controls
Smart landscape lighting systems with app control, scheduling, and zone management add $200 – $800 to the base cost but provide significant convenience and energy savings over time.
Timer or Photocell Controls
Adding a timer or dusk-to-dawn photocell sensor to automatically control when lights turn on and off costs $20 – $100 for the hardware, plus labor to install.
Permit Fees
Line-voltage landscape lighting typically requires a permit in most jurisdictions. Permit fees range from $50 – $200 and may be included in the electrician’s estimate.

When to Hire a Licensed Electrician
While low-voltage landscape lighting is DIY-friendly — though any line-voltage work must meet National Electrical Code (NEC) requirements —, hire a licensed electrician for:
- Line-voltage (120V) fixture installation
- Adding new outdoor circuits or GFCI outlets
- Extensive underground wiring runs
- Projects requiring permits or inspections
- Integrating landscape lighting into a smart home system
Professional installation ensures all connections are weatherproof, code-compliant, and safe for long-term outdoor exposure.
Tips for Keeping Costs Down
- Start with a low-voltage system — it delivers great results at a fraction of the cost of line-voltage
- Install multiple fixtures in a single project visit to reduce labor costs
- Choose LED fixtures to minimize energy consumption and bulb replacement
- Plan the layout yourself and share it with your electrician to reduce design fees
- Get multiple quotes from licensed electricians before committing
Landscape Lighting Design and Fixture Selection
Landscape lighting transforms outdoor spaces and adds significant curb appeal, but fixture choice and placement heavily impact both cost and results. LED fixtures ($30–$200 each) have largely replaced halogen and incandescent, offering superior efficiency, longevity (50,000+ hour lifespan vs. 2,000–10,000 hours), and color rendering. Common landscape lighting types include: path lights (solar or low-voltage, $20–$60 each) for walkway safety; uplights ($40–$150 each) to highlight trees, shrubs, or architectural features; spotlights ($50–$200 each) for accent lighting; flood lights ($80–$300 each) for broad area coverage like decks or patios; and string lights or bistro lights ($100–$400 for 20–50 foot runs) for ambiance over seating areas. A professionally designed landscape lighting plan typically costs $200–$500 (consultation and design drawing) but prevents costly fixture overbuying and aesthetic missteps. Most homes benefit from a combination of accent, path, and ambient lighting rather than uniform bright illumination; layered lighting creates visual interest and can cost less than you’d expect if fixtures are thoughtfully selected. Before hiring an electrician, consider consulting a landscape lighting specialist—their expertise in color temperature (warm 2700K for inviting spaces vs. cool 5000K for security), brightness levels (50–200 lumens for path lights, 500+ for flood lights), and fixture positioning ensures superior results.
Wiring, Outdoor Circuits, and Weatherproofing Standards
Landscape lighting requires either low-voltage (12V or 24V) or line-voltage (120V) wiring, each with distinct installation requirements and costs. Low-voltage systems use a transformer (plugged into a standard outdoor outlet) and small-gauge wiring that runs through landscaping and under turf—labor is minimal and DIY is feasible, but the setup requires a dedicated outdoor circuit ($200–$400 if not already present). Line-voltage landscape lighting draws from standard 120V circuits and requires professional installation with proper conduit protection, GFCI-protected outlets, and buried or protected wiring to meet NEC Article 680 (outdoor wiring standards). Line-voltage fixtures are brighter and more suitable for large areas but cost more to install ($1,200–$2,500 for comprehensive landscape lighting) because every wire, junction, and fixture must be weatherproofed and code-compliant. All outdoor electrical work must include GFCI protection (ground fault circuit interrupter) to prevent shock hazards if moisture enters connections. Conduit routing is critical: wires must be buried 18 inches deep (12 inches under pavement) to avoid damage from digging, and junction boxes must be accessible, weatherproofed, and rated for wet locations. Discuss your landscape design and desired lighting coverage with your electrician early to determine whether low-voltage (cheaper, lower-voltage, less regulated) or line-voltage (brighter, more powerful, code-regulated) best fits your needs and budget.
Maintenance, Seasonal Considerations, and Long-Term Costs
LED landscape lighting requires minimal maintenance—fixtures typically last 10–15+ years before dimming becomes noticeable. However, outdoor fixtures accumulate dirt, algae, and corrosion, especially in coastal or humid climates; annual cleaning (wiping lenses, clearing debris from around fixtures) maintains light output and appearance. Seasonal considerations affect costs: landscape lighting is most desirable installed before late spring (allowing full summer enjoyment) and before fall (for holiday displays), making off-season installations (winter, early spring) potentially cheaper if contractors offer discounts for slower periods. Motion-sensor landscape lights ($100–$250 each) are increasingly popular for security purposes and reduce energy consumption by activating only when motion is detected. Smart landscape lights ($150–$400 each) with WiFi or app control allow remote on/off switching, scheduling, and dimming—valuable if you travel frequently or want customizable scenes for entertaining. If you’re installing smart or sensor-enabled landscape lighting, ensure your electrician provides proper surge protection and circuit-level GFCI protection to prevent false triggers from electrical noise on the circuit. Over the 10–15 year lifespan of quality LED landscape lighting, you’ll recoup installation costs through curb appeal improvement, added security, and extended outdoor living season enjoyment.
