PR-402 Abu Dhabi Lighting Manual (officially the Abu Dhabi Lighting Manual
) is the primary regulatory document for the design, installation, and maintenance of public and roadway lighting within the Emirate. The current active version is Version 3.0 , released in Key Specifications and Requirements
The manual outlines technical standards for street, tunnel, and public realm lighting, focusing heavily on sustainability and energy efficiency. LED Standards
: Mandatory use of LED luminaires for all new and retrofit projects. Color Temperature (CCT) : Accepted ANSI standard LED colors are 2700K, 3000K, and 4000K Lighting Classes
: Defines specific luminance and illuminance levels based on road type: Highways/Freeways (100+ Kph) : Class M2 or M4 with specific uniformity ratios. Major Arterials (80 Kph) : 1.0 cd/m² average luminance. Design Constraints Maximum bracket arm length: Maximum luminaire tilt angle: Warranty: Minimum 10-year full warranty for street and tunnel lighting fixtures.

The PR-402 Abu Dhabi Lighting Manual (officially the Lighting Design Manual) is a comprehensive technical standard used by engineers and consultants for designing public and roadway lighting in the Emirate of Abu Dhabi.
The most recent version (Version 3.0, released in July 2021) prioritizes high-efficiency LED technology and strict durability requirements suited for the local climate. Key Technical Specifications
The manual provides rigorous guidelines for different types of outdoor lighting:
LED Color Temperatures: Standard accepted colors for roadway and parking lighting are 2700K, 3000K, and 4000K.
Performance Levels: Lighting classes (e.g., M2, M4) are assigned based on road type, with specific requirements for luminance (e.g., 1.0 to 1.5 cd/m²) and uniformity ratios.
Fixture Durability: Luminaires must have a minimum useful life of 50,000 hours (L70) at an ambient temperature of 35°C. pr 402 abu dhabi lighting manual free
Environmental Protection: High standards for Ingress Protection (IP) and Impact Protection (IK) are mandatory to withstand sandstorms and extreme heat. Critical Design Requirements PR-402 2021-579 | PDF - Scribd
The PR-402 Lighting Manual (also known as the Abu Dhabi Lighting Design Manual) is a mandatory technical standard issued by the Department of Municipalities and Transport (DMT) for all public lighting projects within the Emirate of Abu Dhabi. Accessing the Manual
While official government portals often require professional registration to access full libraries, the manual is frequently available for review or download via several public and semi-public platforms:
Official E-Library: The Department of Municipalities and Transport (DMT) E-Library provides infrastructure guidelines that reference PR-402 and sometimes host the full PDF.
Industry Repositories: Professional documents like Version 3.0 (July 2021) are hosted on platforms such as Scribd and through community-shared links on LinkedIn.
Government Quality Portals: Specific technical specifications for LED luminaires used in conjunction with PR-402 can be found at Jawdah (QCC). Key Technical Standards
The manual establishes strict requirements for visibility, energy efficiency, and safety for roadways and parking areas:
Lighting Classes: Defines specific luminance levels (e.g., Class M2 requires ~20-25 lux; Class M4 requires ~15 lux) based on roadway type and traffic speed.
LED Requirements: Standardized Correlated Color Temperatures (CCT) are typically 2700K, 3000K, and 4000K.
Hardware Specs: Limits luminaire tilt to 5 degrees and bracket arm lengths to 1.5m to minimize glare and light pollution.
Environmental Policy: Designs must align with the Abu Dhabi Dark Sky Policy to reduce light spill and protect the nocturnal environment. Structure of the Manual PR-402 Abu Dhabi Lighting Manual (officially the Abu

The PR-402 Abu Dhabi Lighting Manual, officially known as the Lighting Design Manual, is a regulatory document issued by the Department of Municipalities and Transport (DMT). It establishes the technical standards and design criteria for roadway, public realm, and tunnel lighting across the Emirate.
The current version in circulation is Version 3.0 (July 2021). Key Specifications of the PR-402 Manual
The manual defines several critical parameters for lighting installations in Abu Dhabi:
LED Color Temperatures: The accepted Correlated Color Temperature (CCT) for roadway and parking lighting projects is restricted to 2700K, 3000K, and 4000K.
Lighting Classes: It categorizes roads into classes (e.g., M2, M4) with specific luminance requirements. For example, Highways (100Kph+) typically require a minimum design level of 1.0 cd/m².
Pole and Bracket Geometry: The manual mandates a maximum bracket arm length of 1.5 meters and a maximum luminaire tilt angle of 5 degrees from the horizontal.
Protection Ratings: Standard roadway luminaires must meet a minimum IP66 (ingress protection) and IK08 (impact protection) rating to withstand local environmental conditions.
Operational Durability: Luminaires must be designed to operate continuously in ambient temperatures up to +50°C. Manual Structure Action: Search for "Building Codes and Standards
The manual is typically divided into sections to cover different infrastructure needs:
Part 1, Section B: Focuses specifically on lighting for tunnels and underpasses.
Part 1, Section C: Details specifications for roadway and parking lighting poles.
Part 2, Section A: Covers lighting for parks and the public realm. How to Access the Manual
While the official document is distributed by the Abu Dhabi City Municipality (ADM) to registered consultants and contractors, digital versions and technical summaries are often found on professional and academic repositories:
Official E-Library: The Department of Municipalities and Transport (DMT) provides infrastructure guidelines that reference the PR-402 manual.
Document Repositories: Detailed extracts and full versions of the Lighting Design Manual PR-402 are available for viewing or download on platforms like Scribd.
