- Residential outdoor lighting in the Seattle Metro Area runs from approximately $3,000 for a starter system to $20,000+ for a full-property design.
- A typical mid-range installation covering driveway path, entry, 2-3 accent lights, and a smart transformer runs $5,000-$10,000.
- Per-fixture cost varies from $50-$150 for budget aluminum to $200-$500+ for professional brass and copper installed.
- Six cost drivers: fixture count, fixture quality tier, cable run length, transformer specifications, site complexity, and electrical integration.
- Operating costs are modest — typical mid-range systems run $5-$15 per month in electricity, with rare bulb replacement on modern LED fixtures.
- Total 15-year cost of ownership for a mid-range system runs $5,500-$11,000 including installation, operating cost, and maintenance.
- DIY makes sense for starter scopes (path lighting under 10 fixtures); professional installation makes sense for layered designs, smart control, or integration with broader landscape work.
Residential outdoor lighting installation in the Seattle Metro Area runs from approximately $3,000 for a starter system (path lighting along a driveway, basic entry lighting) to $20,000+ for a full-property design integrating path, step, accent, deck, and tree lighting. A typical mid-range residential installation — covering driveway path, entry, 2-3 specimen accent lights, and a smart-controlled transformer — runs $5,000-$10,000. Per-fixture cost varies substantially by fixture quality tier: budget-grade aluminum runs $50-$150 per fixture installed; professional-grade brass and copper runs $200-$500+ per fixture installed. The cost difference reflects fixture lifespan (5-7 years versus 25+ years), light quality, and finish durability. Smart-controlled transformers add modest cost during installation and substantial day-to-day usability after.
What does typical lighting pricing look like?
Residential outdoor lighting pricing breaks down by project tier:
Starter system ($3,000-$5,000):
- Path lighting along driveway and front walkway (6-10 fixtures)
- Basic entry lighting
- Standard transformer with photocell or simple timer
- Light installation scope, suitable for compact properties or initial introduction to outdoor lighting
Mid-range system ($5,000-$10,000):
- Path lighting (front and side)
- Step and grade lighting where applicable
- 2-3 specimen accent lights (specimen trees, focal plantings)
- Entry and facade lighting
- Smart-controlled transformer with WiFi integration
- Standard for typical residential properties
Premium system ($10,000-$20,000+):
- Full path lighting throughout the property
- Multiple accent lighting on specimen plants and architectural features
- Deck and patio integrated lighting
- Tree up-lighting and down-lighting (moonlighting effect)
- Multiple smart-controlled transformers for separately controlled zones
- Higher fixture quality tier throughout (brass and copper)
- Suitable for larger properties or properties where outdoor design carries significant aesthetic weight
The outdoor lighting design approach covers what each lighting category accomplishes and how the layered effect works. For projects where lighting integrates with other enhancement work, our Landscape Enhancements service combines lighting installation with adjacent projects efficiently.
What drives the cost difference between systems?
Six factors shape outdoor lighting pricing:
Fixture count. The most predictable variable. Each additional fixture adds material plus labor. Path lighting typically uses 6-12 fixtures depending on length; accent lighting uses 1-3 fixtures per specimen.
Fixture quality tier. Budget aluminum versus professional brass and copper. The quality tier shows up in lifespan, finish durability, and lens optical quality. Professional-grade fixtures cost 2-4x more than budget fixtures but last 4-5x longer.
Cable run length and trenching complexity. Lighting systems require cable runs from transformer to fixtures, typically buried in shallow trenches. Longer runs through hardscape or under driveways add substantially to install time.
Transformer specifications. Basic transformers cost less; smart-controlled transformers with WiFi integration, astronomical clock, and scene control cost more. The smart-control premium is typically $400-$800 — modest for the daily usability gain.
Site complexity. Properties with significant slope, mature trees requiring careful trenching, or limited site access all add labor time. Established landscapes with existing planting beds require more careful routing than new landscapes where lighting can be installed during initial construction. Coordinating lighting installation with other fall hardscape projects can reduce overall site disruption — see our fall hardscape installation guide for how the timing works together.
Electrical integration. Standalone low-voltage systems don’t require electrical permits; line-voltage integration (facade lighting integrated with home electrical, GFCI outlets near fixture clusters) requires licensed electrician work and adds cost.
How do operating costs compare to upfront cost?
LED outdoor lighting operating costs are modest. A typical mid-range residential system running on schedule (dusk to midnight, plus selective fixtures running until dawn) consumes roughly 50-100 kWh per month — approximately $5-$15 per month at typical Pacific Northwest electricity rates.
Bulb replacement is rare with modern LED fixtures — professional-grade LEDs typically run 50,000+ hours of life (roughly 25 years at typical residential use). Budget LEDs run 15,000-25,000 hours (5-10 years at typical use). Replacement bulb cost is modest when needed; the labor to access fixtures often costs more than the bulb itself.
System maintenance is similarly modest. Annual or biannual inspection (replacing failed fixtures, cleaning lenses, adjusting aim) typically runs $200-$400 per visit for professional service, or zero cost for DIY maintenance.
The total cost of ownership over a 15-year horizon for a mid-range system is roughly $5,500-$11,000 ($5,000-$10,000 installation plus $500-$1,000 in operating cost and modest maintenance). The cost-per-year-of-use translates to substantial value for systems that transform the usable hours of outdoor space.
When does DIY outdoor lighting make sense?
Low-voltage outdoor lighting is one of the more DIY-friendly landscape categories — the components are designed for retrofit, the trenching is shallow, and no electrical permits are typically required.
DIY makes sense when:
- The project scope is starter-level (path lighting along a defined route, basic entry)
- You’re comfortable with shallow trenching and basic electrical connections
- The fixtures and transformer are matched correctly (transformer wattage rating matches total fixture load)
- The trenching path doesn’t run through hardscape or under driveways
Professional installation makes sense when:
- The scope includes design decisions (which features to light, what brightness layers, where shadow should fall)
- Fixture count exceeds 12-15 (system complexity grows fast)
- Smart-control integration matters for ongoing usability
- The lighting is part of a broader landscape enhancement (integrated with hardscape, planting, or structural work)
The cost difference for DIY versus professional starter systems ($1,500-$2,500 versus $3,000-$5,000) can favor DIY for simple scopes. The cost difference narrows on larger projects because professional efficiency scales while DIY effort does not.
