Street Light Calculator: Pole Height, Spacing & Quantity Estimator

What Is This Street Light Calculator?

This street light calculator helps engineers, contractors, municipal planners, and infrastructure developers estimate the required pole height, lamp wattage, pole spacing, and total street light quantity for road lighting projects.

The calculation is based on commonly used roadway lighting design practices, allowing users to quickly generate a preliminary lighting layout for municipal roads, highways, industrial parks, rural roads, parking lots, and public infrastructure projects.

For detailed project design, lighting simulation, and solar system engineering, professional evaluation is recommended.

Who Is This Calculator For?

Municipal Roads

Estimate lighting layouts for city roads and urban transportation corridors.

Highways

Plan pole spacing and wattage for major roadways and highway projects.

Industrial Parks

Calculate lighting requirements for logistics centers and industrial developments.

Rural Roads

Design cost-effective lighting systems for villages and off-grid roads.

Parking Lots

Estimate outdoor lighting coverage for commercial and public parking areas.

Government Infrastructure

Support preliminary planning for municipal and public infrastructure projects.

Engineering Formulas Explained

Pole Height Formula

Pole Height ≈ Road Width × 0.8–1.2

Pole Spacing Formula

Pole Spacing = Pole Height × 3–4

Street Light Quantity Formula

Total Lights = Road Length ÷ Pole Spacing + 1

Wattage Selection Guide

Recommended LED wattage based on pole height and roadway application.
