Pr 402- Abu Dhabi Lighting Manual -
Issued by the Department of Municipalities and Transport (DMT), the PR 402, also referred to as TR-402 , is a comprehensive reference document that consolidates a wide range of lighting requirements into a single source. This standardization eliminates the need to consult multiple international and local codes, providing clear and consistent guidance for architects, engineers, and developers to design lighting systems that are safe, efficient, and environmentally responsible. The manual is a key component of the emirate's technical regulations, formally listed as the under the Jawdah (QCC) system.
: Neutral white tones (up to 4000K) are permitted to maximize visual acuity and contrast detection for high-speed driving.
A minimum CRI of 70 is standard for roadways, while pedestrian zones and parks often require a CRI of 80 or higher to ensure accurate color differentiation. Sustainability and Environmental Protections

By enhancing energy efficiency and reducing light pollution, compliance with PR-402 is crucial for projects aiming for higher Estidama Pearl Rating System certification. Conclusion
Version 3.0, released in July 2021, focuses heavily on modern LED technology, energy efficiency, and reducing light pollution. 1. Scope and Objectives of PR-402 : Neutral white tones (up to 4000K) are
Performance modeling must be completed using validated lighting simulation software (such as Dialux or Relux). Designers must utilize certified Photometric Web files (.IES or .LDT) provided by approved manufacturers.
The PR-402 lighting manual is part of a broader set of Public Realm Design Manuals (PRDM). Its primary objectives include:
Luminaires must have a minimum efficacy (often cited around 100lm/W) and be tested for dust and sand resilience, reflecting the local environmental challenges.
