didn’t just want better bulbs; they wanted a new aesthetic. The goal was to bring the city's daytime beauty—its architecture and landscaping—into the night with clarity. They introduced LED technology

PR 402 positions Abu Dhabi as a global leader in smart infrastructure. It mandates that all newly installed public lighting infrastructure must be future-proof.

: It establishes a schedule of lighting levels for different traffic routes, such as Highways (Class M2/M4) and Major Arterials, defining parameters like minimum average luminance ( cap L sub a v end-sub ), illuminance ( cap E sub a v end-sub ), and uniformity ratios ( cap U sub 0 Color Standards

The PR-402 Abu Dhabi Lighting Manual provides a balanced framework that merges technical engineering rigor with ecological responsibility. By standardizing high-performance LED technology, smart controls, and strict structural durability, the manual ensures that Abu Dhabi's nocturnal landscape remains safe, visually inspiring, and economically sustainable for generations to come. pr 402- abu dhabi lighting manual

Generating detailed Dialux or Relux calculations demonstrating compliance with lux, uniformity, and glare requirements.

PR-402 provides a comprehensive, unified standard for various urban applications, including roadways, tunnels, and open spaces. Technical Specifications and Requirements

Structural uniformity limits ensure there are no dangerous dark patches on multi-lane highways. Pedestrian and Conflict Areas (C and P Classes) didn’t just want better bulbs; they wanted a new aesthetic

Professionals should subscribe to DMT notifications and attend the annual Abu Dhabi Lighting Forum for early insights.

Publicly visible exterior illumination on commercial, residential, and government buildings. Key Technical Parameters and Lighting Classes

PR 402 leaves no room for ambiguity. It provides precise metrics that every outdoor lighting design must satisfy before receiving municipal approval. Correlated Color Temperature (CCT) It mandates that all newly installed public lighting

: Specifications include pole height (e.g., 20m for highways), spacing (80–95m), and median arrangements.

A sustainable city must also be a safe city. The manual specifies technical requirements for illuminance (how much light falls on a surface) and uniformity ratios. This ensures that roads, walkways, and parks are safe for the public, preventing accidents and deterring crime through consistent, well-designed lighting levels.

Standardized levels (e.g., M2 for high-speed roads at 1.3–1.5 ; M4 for minor routes at 1.0 LED Specifications:

| Road / Area Type | Average Maintained Illuminance (Lux) | Uniformity (Uo) | Glare Rating (GR) | |----------------|--------------------------------------|----------------|-------------------| | Arterial Roads | 20 – 30 lx | ≥ 0.4 | ≤ 25 | | Collector Roads | 15 – 20 lx | ≥ 0.35 | ≤ 25 | | Local Streets | 10 – 15 lx | ≥ 0.3 | ≤ 28 | | Pedestrian Zones | 5 – 15 lx | ≥ 0.25 | N/A | | High-Risk Intersections | 40 – 50 lx | ≥ 0.5 | ≤ 25 |

The Upward Light Ratio (ULR) for street luminaires must be 0%, meaning no direct light is emitted above the horizontal plane.
