Car Park Lighting Pole Spacing Guidelines & Standards
Car Park Lighting Pole Spacing Guidelines: Complete Guide
Proper car park lighting pole spacing is essential for achieving uniform illumination, safety, and energy efficiency. Whether designing a new parking area or upgrading an existing one, understanding spacing guidelines helps avoid dark spots, glare, and unnecessary costs.
In this guide, we’ll explain how to determine optimal spacing, key influencing factors, and relevant international standards.

Why Pole Spacing Matters in Car Park Lighting
Correct pole spacing directly impacts:
- Uniformity of lighting (reduces dark zones)
- Driver and pedestrian safety
- Energy efficiency and cost control
- Compliance with lighting standards
If poles are too far apart, illumination becomes uneven. If too close, you waste energy and increase installation costs.
Key Factors Affecting Pole Spacing
Several variables determine the correct spacing:
1. Mounting Height
Higher poles allow wider spacing. A common rule:
- Spacing = 2.5 to 4 times the pole height
2. Light Distribution Pattern
Different beam angles affect coverage:
- Type II / III: Narrow to medium distribution
- Type IV / V: Wide distribution (ideal for car parks)
3. Required Illuminance (Lux Levels)
Typical car park requirements:
- Low activity: 5–10 lux
- Medium activity: 10–20 lux
- High activity: 20+ lux
4. Uniformity Ratio
Standards often require:
- Uniformity ratio ≤ 4:1 (max/min)
Proper lighting should minimize dark areas
Recommended Pole Spacing Table
Below is a general reference for car park lighting pole spacing guidelines:
| Pole Height | Recommended Spacing | Typical Application |
|---|---|---|
| 4–5 meters | 10–15 meters | Small parking areas |
| 6–8 meters | 15–25 meters | Medium car parks |
| 9–12 meters | 25–40 meters | Large outdoor parking |
| 12+ meters | 35–50 meters | Commercial & industrial |
Note: These are general guidelines. Final spacing should be confirmed through lighting simulation (e.g., Dialux).
International Standards for Car Park Lighting
To ensure compliance and quality, follow recognized standards:
- Illuminating Engineering Society (IESNA RP-20)
Provides recommended practices for parking facility lighting. - Standards Australia (AS/NZS 1158 & AS 4282)
Covers outdoor lighting and glare control in Australia and New Zealand. - European Committee for Standardization (EN 12464-2)
Specifies lighting requirements for outdoor workplaces.
These standards define minimum lux levels, uniformity, and glare limitations.
How to Calculate Optimal Pole Spacing
A simplified method:
- Determine required lux level
- Select luminaire output (lumens)
- Choose mounting height
- Apply spacing ratio (2.5–4× height)
- Validate using lighting design software
For professional projects, simulation tools ensure compliance and efficiency.
Best Practices for Better Results
- Use LED fixtures with wide beam angles
- Avoid over-spacing to maintain uniformity
- Consider asymmetrical optics for parking layouts
- Reduce glare with proper fixture selection
- Always verify with lighting calculations
Brands like VIPLED focus on engineered optics and consistent performance, helping achieve better spacing efficiency and long-term reliability.
Conclusion
Following proper car park lighting pole spacing guidelines ensures safe, efficient, and compliant lighting design. By considering pole height, light distribution, and international standards, you can achieve optimal results while controlling costs.
