How Much Does Outdoor Lighting Cost in Franklin, TN? (2026 Pricing Guide)
If you’ve been thinking about adding outdoor lighting to your home in Franklin, Brentwood, or anywhere across Williamson County, the first question on your mind is probably the same one we hear every week: how much is this going to cost?
The honest answer is that outdoor lighting cost in Franklin, TN depends on several factors, the size of your property, the number of fixtures, the type of lighting system, and the complexity of the design. But after hundreds of installations across Williamson County, we can give you a clear, realistic picture of what to expect in 2026.
Residential Landscape Lighting Cost in Williamson County
For most homes in Franklin, Brentwood, Spring Hill, and Nolensville, a professionally designed and installed residential outdoor lighting system ranges from $2,000 to $6,000.
Here’s how that breaks down:
Starter accent package (8–12 fixtures): $1,500–$2,500 This typically covers pathway lighting, a few uplights on trees or architectural features, and a programmable transformer. It’s a solid starting point for homeowners who want to enhance curb appeal without a full landscape lighting design.
Mid-range system (15–25 fixtures): $2,500–$4,500 This is the most common range for homes in established Williamson County neighborhoods. It covers the front elevation, key trees, pathways, and entry features with a well-designed system that looks cohesive from the street.
Full custom design (25+ fixtures): $4,500–$8,000+ Larger properties with mature trees, long driveways, pool areas, patio spaces, and detailed architectural features fall into this range. These systems are designed from scratch to highlight your specific property.
What Factors Affect the Cost?
Number of fixtures — Each professionally installed fixture typically runs $100 to $350 installed, depending on fixture type and complexity.
Transformer size — Low voltage landscape lighting systems require a transformer that converts your home’s 120V power to a safer 12V. Transformers range from $150 for basic units to $600+ for programmable, multi-zone units with smart controls.
Trenching and wiring — On properties with long runs, buried wiring adds to the cost. Most installations in Franklin use direct-burial low voltage cable that doesn’t require conduit.
Fixture quality — There’s a significant difference between professional-grade brass and copper fixtures and the plastic fixtures sold at home improvement stores. Professional fixtures cost more upfront but last 15–25 years. Big-box store fixtures typically need replacing within 3–5 years.
Terrain and accessibility — Properties with steep grades, mature root systems, or difficult access around the home take more time to install properly.
Christmas Lighting Installation Cost in Franklin, TN
Professional Christmas light installation is a separate service from landscape lighting, and pricing is typically structured differently, usually by linear foot of roofline, number of trees wrapped, and overall property size.
For most homes in Franklin and Brentwood, professional Christmas lighting installation runs $400–$1,500 for installation, with full-service packages (installation, takedown, and storage) typically ranging from $600–$2,000 per season.
The advantages of professional installation go beyond convenience. Commercial-grade Christmas lights are significantly brighter and more durable than retail options, and having everything stored and reinstalled each year means you get a consistent, polished result without the ladder trips.
Outdoor Lighting Repair Cost
If you have an existing system that needs attention, outdoor lighting repair costs are generally much lower than new installation. Common repair scenarios across Williamson County: Common repair scenarios in Williamson County:
- Burnt-out LED replacement: $50–$150 per fixture
- Transformer replacement: $200–$500 installed
- Wiring repair (cut or damaged wire): $120–$400 depending on severity
- Full system diagnostic visit: $75–$150 service call
One thing worth knowing: we repair outdoor lighting systems that we didn’t install. If you moved into a home with an existing system that isn’t working, or if a previous contractor’s work has developed issues, we can diagnose and fix it regardless of who put it in originally.
Is Outdoor Lighting a Good Investment?
For homes in Williamson County, the answer is consistently yes. A well-designed outdoor lighting system adds perceived value to your property, extends the usability of outdoor spaces into the evening hours, and provides a meaningful security benefit by eliminating dark areas around the home.
Industry data suggests homeowners see a return of 50–70% on professional landscape lighting when selling, and in a competitive real estate market like Franklin and Brentwood, curb appeal at night matters more than most sellers realize.
