Driveway Lighting Calculator
Calculate driveway lighting requirements including number of lights, optimal spacing, total lumens, and energy consumption for perfect outdoor illumination.
Step 1: Driveway Specifications
Lighting Spacing Formula
Number of Lights = Driveway Length ÷ Spacing Distance
Optimal spacing: 8-15 feet between lights for most driveways.
Step 2: Lighting Specifications
Recommended Lighting Levels
Residential driveways: 100-200 lumens per fixture
Security lighting: 300-500+ lumens
Path lighting: 50-100 lumens
Accent lighting: 50-150 lumens

Driveway Lighting Formula & Guidelines
Number of Lights = Driveway Length ÷ Spacing Distance
Where:
• Driveway Length = Total length in feet
• Spacing Distance = Distance between lights (8-15 feet recommended)
• Total Lumens = Number of Lights × Lumens per Light
• Total Wattage = Number of Lights × Watts per Light
Energy Cost Calculation:
• Daily kWh = (Total Wattage × Hours per Day) ÷ 1000
• Monthly Cost = Daily kWh × 30 × Electricity Rate ($/kWh)
Lighting Guidelines
Recommended Practices
• Space lights 8-15 feet apart for adequate coverage
• Mount lights 18-24 inches above ground for path lighting
• Use 100-200 lumens per fixture for residential driveways
• Install motion sensors for security areas (500-1500 lumens)
• Consider solar lights for energy efficiency
• Use warmer color temperatures (2700K-3000K) for residential areas
• Ensure lighting doesn’t spill onto neighboring properties
