Pr 402- Abu Dhabi Lighting Manual May 2026
After installation, a photometric field test is mandatory. The contractor must provide a test report using a calibrated luminance meter, comparing five random points to the design predictions. Tolerances: ± 7% for L avg; ± 10% for E min.
PR 402 represents a maturity in Abu Dhabi’s urban planning journey. It signals that the emirate is no longer just building structures, but curating experiences.
For consultants and contractors, mastering the nuances of the Abu Dhabi Lighting Manual is essential not just for compliance, but for contributing to a legacy of sustainable urbanism. As technology evolves, these standards will continue to push the boundaries of what is possible, proving that the best lighting designs are the ones that respect both the people and the planet.
Are you working on a project that requires compliance with PR 402? Ensure your lighting design consultants are up to date with the latest DMT regulations to streamline your approval process.
This review evaluates the document based on its technical merit, regulatory impact, aesthetic guidelines, and its role within the wider context of urban planning in the Emirate.
The PR 402- Abu Dhabi Lighting Manual is more than just a technical document—it is the legal and professional standard for external lighting in the emirate. Ignoring its specifications leads to costly redesigns, project delays, and safety risks. Conversely, mastering its clauses positions you as a trusted expert in one of the world’s most ambitious urban environments.
Whether you are designing a parking lot in Musaffah or a tunnel on Sheikh Zayed Road, always start with PR 402. Download the latest version from the Abu Dhabi Municipality ePortal, calibrate your software to its parameters, and when in doubt, consult the municipality’s lighting helpdesk.

The Abu Dhabi Lighting Manual (PR-402), specifically the latest Version 3.0 (July 2021), is the definitive technical standard for public lighting design within the Emirate. It establishes mandatory guidelines for the Department of Municipalities and Transport (DMT) to ensure energy efficiency, road safety, and sustainability. Key Technical Standards pr 402- abu dhabi lighting manual
Designers and contractors must adhere to specific performance metrics for LED installations:
Lighting Classes: Standardized levels (e.g., M2 for high-speed roads at 1.3–1.5 ; M4 for minor routes at 1.0 LED Specifications:
Color Temperature (CCT): Standard accepted colors are 2700K, 3000K, and 4000K.
Protection: Luminaires must meet high Ingress Protection (IP) and Impact Protection (IK) ratings.
Warranty: Minimum 10-year full warranty required for street and tunnel lighting. Physical Infrastructure:
Poles: Maximum bracket arm length is typically 1.5m with a maximum tilt angle of 5 degrees.
Clearance: A 1000mm clear area is required around pole centers, typically finished with hardscape or gravel. Scope of the Manual
PR-402 is divided into comprehensive sections covering the full lifecycle of a lighting project: Focus Area Section A & B Roadway, Parking, Tunnel, and Underpass Lighting Section C Street Lighting Poles and foundations Section D Public Lighting Management Systems (PLMS) & Dimming Section E & F Solar Street Lighting and Gantry/Signage Lighting Section G Light Pollution Mitigation (Dark Sky Policy compliance) Section H Project Submission & Verification Requirements Compliance & Submission PR-402 (Lighting Design Manual) | PDF - Scribd
The PR-402 Abu Dhabi Lighting Manual is a comprehensive technical document issued by the Abu Dhabi Department of Municipalities and Transport (DMT) to regulate the design, installation, and maintenance of public lighting across the Emirate. Its primary goal is to ensure a safe, sustainable, and aesthetically pleasing night-time environment by standardising lighting requirements for roadways, parking areas, and other public spaces. Purpose and Scope After installation, a photometric field test is mandatory
The PR-402 manual serves as a mandatory guideline for all municipal projects in Abu Dhabi. It was updated in 2021 (Version 3.0) to incorporate international best practices and technical circulars, unifying the approach for developers, planners, and engineers. The manual focuses on:
Safety: Establishing specific lighting levels for different road types (e.g., highways, arterials, and local streets) to improve visibility and reduce traffic accidents.
Sustainability: Mandating the use of energy-efficient LED technology and strict light control to reduce energy consumption and light pollution.
Quality & Reliability: Setting rigorous specifications for materials to withstand Abu Dhabi's harsh climatic conditions, including extreme heat, humidity, and sandstorms. Key Technical Specifications
The manual outlines detailed performance and material standards for lighting infrastructure:
Lighting Classes: Defines classes such as M2 and M4 based on luminance levels (e.g., 1.0 to 1.5 cd/m²) and uniformity ratios tailored to vehicle speed and road type.
LED Criteria: Specifies acceptable Correlated Colour Temperatures (CCT)—typically 2700K, 3000K, or 4000K—and requires high Colour Rendering Index (CRI) to ensure visual clarity.
Infrastructure Design: Includes guidelines for pole heights (e.g., 20m for highways), spacing (80-95m), bracket arm lengths (max 1.5m), and foundation requirements to resist high wind speeds.
Protection Standards: Requires luminaires to have high Ingress Protection (IP) and Impact Protection (IK) ratings to ensure durability against dust and physical damage. Impact and Significance PR 402 represents a maturity in Abu Dhabi’s
By implementing the PR-402 standards, Abu Dhabi has transitioned from traditional, energy-intensive street lighting to advanced LED systems that can save significant energy—up to 40–60% in some projects. This standardisation supports the broader Abu Dhabi Sustainable Lighting Strategy, which aims to save over AED 1 billion in energy costs by 2030 while enhancing the Emirate's urban liveability and safety.

Refer to PR 402 Table 2.1 (or latest version) based on road classification from the department’s planning section. Do not assume; cross-check with Abu Dhabi’s integrated transport master plan.
As of 2025, Abu Dhabi Municipality is actively drafting PR 402 Version 4.0. Expected changes include:
Staying ahead of these updates is critical for any lighting professional operating in the region.
Abu Dhabi is a global leader in the UAE’s Net Zero 2050 initiative. PR 402 explicitly encourages:
The PR 402 Abu Dhabi Lighting Design Manual (Version 3.0, July 2021) acts as the primary regulatory document for infrastructure lighting, focusing on energy efficiency and sustainability. It defines stringent standards for LED color temperature, durable materials, and specific lighting classes for roadways and tunnels to enhance safety and reduce power consumption.
