How to Calculate Parking Lot Lighting

When designing a well-lit parking lot, it's essential to consider various factors like light distribution, brightness levels, and energy efficiency. Proper lighting ensures safety, security, and compliance with regulations.

Key Considerations for Parking Lot Lighting

Before calculating the lighting requirements, consider these critical aspects:

• Illumination Standards: Parking lot lighting should meet local regulations and industry standards like IES (Illuminating Engineering Society) guidelines.

• Uniformity Ratio: Consistency in lighting reduces dark spots and improves visibility.

• Light Pole Placement: Proper positioning avoids glare and shadows.

• Energy Efficiency: Opt for LED lighting solutions to minimize power consumption and maintenance costs.

How to Calculate Parking Lot Lighting

1. Determine the Required Illuminance Level

Different parking areas require varying light levels, typically measured in foot-candles (fc) or lux. For general parking lots:

• Low-traffic areas: 0.5 fc (5 lux)

• Medium-traffic areas: 1.0 fc (10 lux)

• High-traffic areas: 2.0 fc (20 lux)

2. Calculate the Total Area

Measure the length and width of the parking lot to determine the total square footage or square meters.

3. Select the Right Light Fixtures

Choosing high-quality LED lighting ensures proper illumination while maintaining energy efficiency. 

Recommended Lighting Solution

For an energy-efficient and high-performance solution, consider the Infralumin 30-150W Outdoor LED Lights. These lights offer superior illumination, withstand extreme temperatures, and provide excellent color rendering for better visibility. With durable safety glass and a power factor above 0.9, they are ideal for parking lot applications.

4. Determine the Number of Fixtures Needed

Use the formula:

Number of fixtures = (Total area * Required illuminance) / (Fixture lumen output * Light loss factor)

5. Consider Light Distribution and Mounting Height

Higher mounting heights require higher lumen outputs. Typically, poles range from 12-30 feet for optimal coverage.

6. Factor in Uniformity and Glare Control

Ensure the chosen fixtures have the right beam angle to distribute light evenly across the lot.
