For engineering consultants and developers, achieving PR-402 compliance requires a structured design submission process to the relevant municipal authorities:

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

The is the definitive technical guideline regulating outdoor lighting across the Emirate of Abu Dhabi. Issued by the Department of Municipalities and Transport (DMT), this manual establishes mandatory standards for roadway, parking, and public realm lighting, ensuring safety, sustainability, and aesthetic cohesion in line with Abu Dhabi Vision 2030.

PR-402 moves away from legacy high-pressure sodium (HPS) systems, establishing Light Emitting Diode (LED) technology as the baseline standard. 1. Color Rendering and Temperature

To achieve its goals, the policy mandates the adoption of specific technologies and strategies:

: Detailed documentation, including certification, testing data, and photometrical analysis, is required for project approval. Maintenance & Warranty

I can provide more targeted details about the if you share a bit more context. Please let me know:

High-speed highways require higher luminance levels (e.g., Class M1 or M2), whereas quiet residential streets utilize lower classes (e.g., Class M5). 2. Pedestrian and Conflict Areas (C and P Classes)

Road classifications dictate column heights, spacing, and outreach arm geometries. High-speed freeways require precise optical distributions to project light efficiently across multiple lanes without wasting energy on off-road buffers. Pedestrian Pathways and Cycle Tracks

Here’s a practical guide to help you track down the correct document or find equivalent authoritative lighting regulations in Abu Dhabi.

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.
