Commercial Landscape Lighting Installation Cost Per Light | 2026 Guide
What is Commercial Landscape Lighting Installation Cost Per Light
The commercial landscape lighting installation cost per light refers to the total installed price per luminaire for exterior lighting systems in commercial properties (hotels, office parks, retail centers, restaurants). Understanding commercial landscape lighting installation cost per light is critical for facility managers, landscape architects, and procurement specialists to budget for pathway lighting, accent lighting (trees, signage), parking lot perimeter lighting, and facade illumination. Typical costs range from $150-600 per light, depending on fixture type (LED path light, well light, floodlight), voltage (12V low voltage vs 120V line voltage), trenching requirements ($20-50 per foot), transformer sizing ($200-800), and local labor rates ($50-150 per hour). This guide provides cost breakdowns by fixture type, installation complexity, voltage drop considerations (12V systems), and procurement specifications for commercial landscape lighting projects.
Technical Specifications Affecting Installation Cost Per Light
The commercial landscape lighting installation cost per light depends on the parameters below.
Fixture Type and Material: Brass path light (commercial grade): $80-150 per fixture. Aluminum path light: $40-80. Stainless steel well light: $100-200. LED floodlight (20W-50W): $60-120. Installation cost: $50-150 per fixture (labor).
Voltage System: Low voltage (12V) – requires transformer ($200-800). Line voltage (120V) – requires licensed electrician, permits, GFCI, conduit. 120V installation costs 2-3x higher than 12V.
Wiring Method: Surface (exposed) – low cost ($2-5 per ft). Trenching (6-12 inches deep) – $10-30 per ft. Trenching in asphalt/pavement – $30-60 per ft.
Wire Gauge (12V systems): 12 AWG ($0.30-0.50 per ft) for runs<80 ft. 10 AWG ($0.50-0.80 per ft) for longer runs. Thicker wire reduces voltage drop but increases material cost.
Transformer Sizing (12V): 300W transformer ($150-300). 600W transformer ($250-500). 900W transformer ($400-800). Labor to install transformer: $100-200.
Number of Fixtures (Volume Discount): 10-20 fixtures: baseline cost per light ($200-400). 50+ fixtures: 15-25 percent lower per-light cost (economies of scale). 100+ fixtures: 25-35 percent lower.
Subgrade Condition: Soft soil (easy trenching) – lower cost. Rocky soil – 2-3x trenching cost. Existing paving – requires saw cutting (+$10-20 per ft).
Labor Rate (Commercial, 2026): South/Southeast: $50-80 per hour. Midwest: $60-90 per hour. Northeast/West Coast: $80-150 per hour.
Permit and Inspection: $100-500 per project (line voltage requires permit; low voltage may be exempt).
Total Installed Cost Per Light (Typical, 30-fixture project): Path light (12V, brass, 30 ft trenching): $200-350 per light. Well light (12V, stainless, 50 ft trenching): $300-500 per light. Floodlight (120V, line voltage, pole-mounted): $400-600 per light.

Common Industry Problems and Engineering Solutions
Real-world failures affecting commercial landscape lighting installation cost per light and corrective actions.
Problem 1: Underestimated Trenching Cost (Rocky Soil). Budget assumed $15/ft, actual $45/ft. Cost overrun $30/ft × 1,500 ft = $45,000. Engineering solution: Conduct soil test before bidding. Use directional boring for rock ($30-50/ft). Consider surface cable (no trench) if soil conditions poor.
Problem 2: Voltage Drop – Lights Dim at End of Run (12V system). Root cause: 12 AWG wire used for 200 ft run with 200W load. Vd = (2 × 12.9 × 16.7A × 200) ÷ 6,530 = 13.2V (110 percent – unacceptable). Engineering solution: Upgrade to 8 AWG or use multiple transformer runs (home-run wiring). Retrofit: add transformer at midpoint.
Problem 3: Transformer Overload (Flicker, Failure). Root cause: Total load 350W on 300W transformer. Engineering solution: Replace with 600W transformer ($250-500). Always load transformer to 80 percent of rating (240W max on 300W).
Problem 4: Fixture Corrosion (Coastal Commercial Property). Root cause: Aluminum fixtures used in salt air. Corroded within 2 years. Engineering solution: Specify brass or stainless steel for coastal projects (+$30-50 per fixture). Apply anti-corrosion coating.
Risk Factors and Prevention Strategies
Key risks affecting commercial landscape lighting installation cost per light and mitigation measures.
Underestimating Trenching Cost (Rock, Pavement): Prevention: Conduct site survey (test bore). Use 20 percent contingency for trenching. For paved areas, use surface-mount fixtures (no trench).
Voltage Drop (Dim Lights): Prevention: Calculate voltage drop before installation. Use 10 AWG for runs >80 ft, 12 AWG for<80 ft. Use multiple transformers (one per zone).
Transformer Overload (Premature Failure): Prevention: Size transformer to 125 percent of total load (80W load → 100W transformer). Add 20 percent for future expansion.
Fixture Corrosion (Coastal, High Humidity): Prevention: Specify brass or 316 stainless steel. Use marine-grade wire nuts. Apply dielectric grease on connections.
Labor Cost Escalation (Licensed Electrician for 120V): Prevention: Use 12V low-voltage system (no license required in most jurisdictions). Reduce permit costs.
Change Orders (Unforeseen Conditions): Prevention: Include 15-20 percent contingency in budget. Conduct thorough site walkthrough before bidding.
Procurement Guide: How to Estimate Commercial Landscape Lighting Installation Cost Per Light
Step-by-step checklist for procurement managers.
Step 1: Count Fixtures and Type. Path lights (30), well lights (10), floodlights (5).
Step 2: Measure Trenching Length (ft). 30 path lights × 50 ft avg = 1,500 ft. 10 well lights × 80 ft = 800 ft. Total 2,300 ft.
Step 3: Determine Soil Condition. Soft soil: $15/ft; compacted: $25/ft; rock: $45/ft. For soft soil, trenching cost = 2,300 × $15 = $34,500.
Step 4: Calculate Fixture and Material Cost. Path lights (brass $80 × 30 = $2,400). Well lights (stainless $120 × 10 = $1,200). Floodlights (12V $80 × 5 = $400). Cable (12 AWG, 2,300 ft × $0.40 = $920). Transformers (600W × 2 = $1,000). Total materials = $5,920.
Step 5: Calculate Labor. 45 fixtures × 1 hour each = 45 hours @ $80/hr = $3,600. Transformer installation (2 × $150) = $300. Total labor = $3,900.
Step 6: Add Contingency (20 percent). Total before contingency = $34,500 (trenching) + $5,920 (materials) + $3,900 (labor) = $44,320. Contingency $8,864. Total $53,184. Per light = $53,184 ÷ 45 = $1,182 per light. (High due to trenching – reduce by using surface cable where possible.)
Step 7: Optimize to Reduce Per-Light Cost. Use surface cable (no trench) for path lights: save $30,000. New total $23,184 ÷ 45 = $515 per light. (More typical.)

FAQ Section
1. What is the average commercial landscape lighting installation cost per light?
2026 average: $150-300 per light (12V low-voltage system, 30-50 fixtures, soft soil, brass fixtures). Higher for line voltage ($400-600) or rocky soil ($300-500).
2. How much does trenching add to the cost per light?
Trenching adds $10-30 per linear foot. For a path light with 50 ft trench, adds $500-1,500 per light if trenching per fixture. However, trenching is shared across multiple fixtures (main line). Surface cable (no trench) eliminates this cost.
3. Is low voltage or line voltage cheaper for commercial landscape lighting?
Low voltage (12V) is significantly cheaper ($150-300 per light) than line voltage (120V) ($400-600+ per light). Low voltage requires no licensed electrician, no conduit, no permit in most jurisdictions.
4. What is the most expensive component of commercial landscape lighting installation?
Trenching is often the largest cost ($10-60 per foot). For a 50-light project with 2,500 ft of trench at $20/ft = $50,000 ( $1,000 per light). Use surface cable (exposed) or reduce trenching depth (6 inches) to lower cost.
5. Do I need a permit for commercial landscape lighting?
Low voltage (12V) systems are often exempt from permits (check local code). Line voltage (120V) requires electrical permit and licensed electrician. Permit costs $100-500 per project.
6. How many fixtures per transformer to minimize cost per light?
Load transformer to 80 percent of rating. For 300W transformer, max 240W. 2W LED path lights → 120 fixtures per 300W transformer. Transformer cost amortized over many fixtures reduces per-light cost.
7. Does fixture material affect installation cost?
Fixture material affects material cost ($30-150), not labor (similar installation time). Brass fixtures cost more ($80-120) but last longer (20+ years). Aluminum ($30-60) may corrode in coastal areas.
8. How can I reduce commercial landscape lighting installation cost per light?
Use surface cable (no trench). Use aluminum fixtures (not brass). Use 2W LED (lower wattage = smaller transformer). Use 12 AWG cable (cost-effective). Bundle multiple fixtures on one transformer. DIY installation (no contractor) saves 30-50 percent.
9. What is the labor cost per light for commercial landscape lighting?
Typical labor: $40-80 per light (0.5-1 hour per fixture at $80/hr). Includes trenching, cable connection, fixture assembly, testing. Higher for well lights (1 hour) vs path lights (0.5 hour).
10. Does voltage drop increase installation cost?
Yes – if calculated incorrectly, you may need additional transformers ($200-800 each) or thicker wire (10 AWG vs 12 AWG, +$0.20-0.30 per ft). Proper design (short runs, multiple transformers) minimizes cost.
