402- Abu Dhabi Lighting Manual [portable] — Pr
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.

: Defines specific luminance (cd/m²) and illuminance (lux) levels based on road type, such as M2 (1.3–1.5 cd/m²) or M4 (1.0 cd/m²). Project Management & Compliance The PR 402 Abu Dhabi Lighting Design Manual (Version 3
: Specifications include pole height (e.g., 20m for highways), spacing (80–95m), and median arrangements. Lighting wasn’t just aimed downward; it was designed
4. Performance Requirements
4.1 Illuminance & Uniformity
- Highways & Major Arterials: Average maintained illuminance (E_avg) ≥ 20 lux, uniformity (U0) ≥ 0.35.
- Local Streets & Access Roads: E_avg ≥ 10 lux, U0 ≥ 0.30.
- Pedestrian & Cycle Paths: E_avg ≥ 5 lux, vertical illuminance at 1.5m height ≥ 3 lux for facial recognition.
- Tunnels (Day/Night): CIE adaptation curve; threshold zone luminance 80–100 cd/m².
Lighting wasn’t just aimed downward; it was designed to create a "silhouette" of vehicles, allowing drivers to see obstacles earlier. The 5-Degree Rule:
The PR 402 manual is a critical document that shapes the outdoor lighting landscape of Abu Dhabi. By providing a comprehensive guide to outdoor lighting, the manual helps to ensure that installations are safe, efficient, and environmentally friendly. Compliance with the manual offers several benefits, including improved safety, energy savings, and environmental benefits. As Abu Dhabi continues to grow and develop, the PR 402 manual will play an increasingly important role in promoting sustainable and well-designed outdoor lighting.
- 2700K luminaires with visors to eliminate spill toward the beach (turtle nesting habitat).
- Dimming to 5 lux between 12 AM – 5 AM.
- Result: Energy savings of 58% vs. initial design, and zero complaints from nearby marine biology stations.
