Landscape Lighting Calculator
Calculate landscape lighting requirements for pathways, gardens, decks, and outdoor spaces. Determine fixtures, wattage, energy costs, and illumination levels for your project.
Step 1: Area & Lighting Type
Lighting Guidelines
Pathways: 8-10 ft spacing • Gardens: 6-8 ft spacing • Decks: 4-6 ft spacing • Security: 10-15 ft spacing. LED fixtures use 75-85% less energy than halogen/incandescent.
Step 2: Power & Usage
Energy Savings Tips
LED Fixtures: Last 25,000+ hours vs 2,000 for halogen
Motion Sensors: Can reduce usage by 70%
Solar Options: Zero operating costs after installation
Timers/Dimmers: Reduce unnecessary usage
