Purpose of this guide: To provide comprehensive information for the design and implementation of street and urban lighting systems according to the European standard EN 13201. This guide is intended for lighting designers, electrical engineers, urban planners, municipal authorities, and contractors involved in the specification and installation of outdoor public lighting.
1. EN 13201 Regulatory Framework
EN 13201 is the principal European standard for road lighting. It establishes the complete framework from road classification to energy performance assessment. Understanding this standard is essential for any professional involved in street lighting design.

The five-step EN 13201 design workflow from road classification to energy assessment.
2. Lighting Classes: M, C, P
EN 13201 defines three families of lighting classes, each tailored to specific road user types and traffic conditions. Selecting the correct lighting class is the foundation of every compliant design.
The three lighting class families defined by EN 13201, each with distinct photometric criteria.
💡 Design Tip: Always begin a street lighting project by classifying the road according to EN 13201-1. The lighting class determines all subsequent photometric requirements. A common error is to skip this step and simply match existing luminaire wattages.
3. Key Photometric Parameters
Understanding the photometric parameters defined in EN 13201-2 is essential for evaluating and comparing lighting designs. Each parameter serves a specific purpose in ensuring visual comfort and safety.

Key Dimensions:
H = Mounting height (m)
OH = Overhang from road edge (m)
W = Road width (m)
α = Tilt angle (0°–15°)
Modern LED: 0°–5° tilt recommended
Larger tilts increase glare & ULOR
Cross-section showing the critical geometric parameters for street lighting design. H, W, OH, and tilt angle must all be modelled in photometric software.
⚠️ Important: In DIALux EVO and RELUX, always model the actual tilt angle and overhang. Even 5° of tilt can shift the peak illuminance by several metres along the road axis, potentially causing the design to fail compliance.

5.1 CCT Selection Guide
LED street luminaires are available in a range of correlated colour temperatures (CCT). In recent years, European and Greek practice has converged on 3000K as the standard for urban street lighting, driven by environmental regulations, dark-sky initiatives, and documented health benefits of reduced blue light emission. Higher CCTs (4000K+) are now reserved for motorways and specific high-speed applications.
Colour Temperature (CCT) Spectrum for Street Lighting

Residential / Ecological / Parks
Urban Streets / Standard (EU)
Motorways only (with caution)
TECHLUMEN recommends 3000K as the default CCT for urban street lighting — aligned with current European and Greek practice. Use 4000K only for motorways or special applications where explicitly required.
CCT
Advantages
Disadvantages
Recommended Use
2700–3000K
Low blue content, warm appearance, dark-sky compliant, reduced ecological impact, preferred by European municipalities
Slightly lower lm/W than neutral white
Urban streets, residential areas, historic centres, ecological corridors — current EU standard
4000K
Higher mesopic efficiency, good visual acuity at speed
Higher blue content, increasingly restricted by regulation
Motorways, high-speed arterials, industrial zones
5000–5700K
Highest scotopic/mesopic efficiency, maximum visual acuity
High blue emission, ecological & health concerns
Motorways, industrial zones (with caution)
6. Energy Performance Indicators (EN 13201-5)
EN 13201-5 introduced two key energy performance indicators that allow objective comparison between different lighting designs. These metrics are increasingly required in public procurement specifications.
6.1 Power Density Indicator (PDI / Dp)
Dp = P / (Lav × S × W) [W / (cd/m² × m²)]
Where P = system power (W), Lav = average maintained luminance, S = pole spacing (m), and W = road width (m). Lower Dp values indicate better energy efficiency.
6.2 Annual Energy Consumption Indicator (AECI / De)
De = Σ(Pi × ti) / (S × W) [Wh/m² per year]
This indicator accounts for dimming profiles and operational hours, rewarding installations with intelligent control strategies.
✅ Procurement Insight: When evaluating tenders, always compare PDI and AECI values. A luminaire with a higher purchase price but significantly lower AECI will almost always be more cost-effective over the 20-year lifecycle of the installation.
7. Smart Controls & Adaptive Lighting
Modern street lighting is increasingly integrated into smart city ecosystems. The combination of LED technology and digital controls enables substantial operational savings.

✅ TECHLUMEN Standard: All TECHLUMEN street luminaires feature full cut-off optics with ULOR = 0% at designed tilt angle. Our standard CCT for urban applications is 3000K, in line with current European practice. For environmentally sensitive areas, 2700K is available on request.
9. Road Surface Properties & R-Tables
For M-class (luminance-based) calculations, the reflective properties of the road surface are critical. EN 13201 uses standardized reduced luminance coefficient tables (r-tables) to model how different surfaces reflect light toward the observer.
R-Table
Surface Type
Reflectance
Character
R1 (C1)
Concrete, light asphalt
Highest
Predominantly diffuse
R2 (N1)
Standard asphalt with light aggregate
Medium-high
Default choice when surface data unavailable
R3 (N2)
Standard dark asphalt
Medium
More specular than R2
R4 (N3–N4)
Smooth, wet, or very dark surfaces
Lowest
Highly specular — worst case
⚠️ Critical: Using R2 when the actual road is dark asphalt (R3/R4) will result in calculated luminance values that cannot be achieved in practice. The difference can be 15–20%, potentially moving the design below the required class. Always confirm the surface type with the road authority.
10. Practical Design Workflow
A systematic design process ensures compliance, optimal performance, and cost efficiency.
Road Classification: Classify each road section per EN 13201-1 (traffic volume, speed, junction density, area type)
Select Lighting Class: Determine appropriate M, C, or P class from the classification matrix
Define Geometry: Establish pole height, spacing, arrangement, tilt, and overhang
Select Luminaire & Optic: Choose luminaire with appropriate optical distribution, wattage, and CCT using IES/LDT files
Photometric Calculation: Run the design in DIALux EVO or RELUX; verify all parameters meet the class
Energy Assessment: Calculate PDI and AECI per EN 13201-5, including dimming profiles
Obtrusive Light Check: Verify EN 12464-2 / CIE 150 compliance for the environmental zone
Documentation: Prepare design report with calculation results, datasheets, and compliance summary
10.1 Maintenance Factor (MF)
MF = LLMF × LSF × LMF × RSMF
Factor
Description
Typical LED Value
LLMF
Lamp Lumen Maintenance Factor (LED depreciation)
0.90–0.95 (at L80B10)
LSF
Lamp Survival Factor (catastrophic failure)
1.00 (LED)
LMF
Luminaire Maintenance Factor (dirt on optic)
0.90–0.95 (IP66)
RSMF
Road Surface Maintenance Factor
1.00 (typically)
💡 Guideline: For LED street lighting, a composite MF of 0.80–0.85 is widely used for a 25-year design life with standard maintenance. Always document the MF assumption in your design report.
11. Common Design Mistakes to Avoid
Mistake
Consequence
Solution
Ignoring the r-table
Calculated luminance not achievable in practice
Confirm actual road surface type; use R3 as conservative default
Over-specifying wattage
Waste energy, excessive glare, over-illumination
Design to the lighting class, not to the replaced lamp wattage
Upgrade class by 1–2 steps at junctions and crossings
No dimming profile
20–40% wasted energy savings potential
Implement at minimum a clock-based dimming schedule
Wrong CCT
Complaints and potential regulatory violations
Use 3000K for urban streets (EU standard); 4000K only for motorways/industrial
12. Total Cost of Ownership (TCO)
The true cost of a street lighting installation extends far beyond the initial purchase price. A proper TCO analysis considers the full 20–25 year lifecycle.

14. Frequently Asked Questions (FAQ)
What is the difference between luminance and illuminance?
Illuminance (lux) measures the amount of light falling on a surface — it is a property of the surface being lit. Luminance (cd/m²) measures the brightness of the surface as seen by an observer — it depends on both the illuminance and the reflective properties of the road surface. M-class roads use luminance because drivers view the road at a low angle; C-class and P-class areas use illuminance.
Can I replace a 250W HPS lamp with a 250W LED?
No — this is a very common mistake. A 250W LED produces approximately 3× more useful light than a 250W HPS due to higher efficacy and directional optics. A typical replacement is 60–100W LED for a 250W HPS, depending on the road class requirements. Always design to the EN 13201 class, not to the old lamp wattage.
Is 5000K or higher CCT acceptable for street lighting?
While some early LED street lighting used 5000–6000K, the trend across Europe — and particularly in Greece — has firmly settled on 3000K as the standard for urban street lighting. Higher CCT luminaires emit more blue light, which has documented negative effects on ecosystems and human health. Most European municipalities now specify ≤3000K for urban roads, with 4000K reserved only for motorways and high-speed roads where mesopic visibility is prioritised. TECHLUMEN recommends 3000K as the default for all urban applications.
What software should I use for street lighting calculations?
The two most widely used professional tools in Europe are DIALux EVO (free, by DIAL GmbH) and RELUX (free, by Relux Informatik AG). Both support EN 13201 calculations with road surfaces, observer positions, and full M-class luminance analysis. TECHLUMEN provides LDT photometric files compatible with both platforms.
What is Zhaga D4i and why does it matter?
Zhaga D4i combines the Zhaga Book 18 mechanical interface (a standardized socket on the luminaire) with the DALI-2 D4i electrical interface. This creates a truly interoperable, future-proof smart lighting platform. You can add sensors, communication modules, or other smart devices from any D4i-compatible vendor — without rewiring or replacing the luminaire. It is the leading standard for smart-ready street lighting in Europe.
How long does LED street lighting actually last?
Quality LED street luminaires are rated at L80B10 at 100,000 hours, meaning after 100,000 operating hours, at least 90% of luminaires will still produce ≥80% of their initial light output. At typical street lighting operating hours (approximately 4,200 hours/year), this equates to roughly 24 years — essentially the full lifecycle of the installation before infrastructure replacement is needed.
