Section B specifically covers lighting for tunnels and underpasses , requiring robust IP (Ingress Protection) and IK (Impact Protection) ratings to withstand sandstorms and high humidity. Access and Compliance
Pro-forma requirements for measuring and evaluating lighting performance in conflict areas and irregular spaces.
The serves as the master framework dictating the design, specification, and implementation of all outdoor lighting systems across the Emirate of Abu Dhabi. Originally introduced to replace fragmented municipal practices, the manual—managed in conjunction with the Abu Dhabi Quality and Conformity Council (ADQCC) and the Department of Municipalities and Transport (DMT)—establishes absolute requirements for infrastructure development. pr 402- abu dhabi lighting manual
: 80–95m median arrangements for major traffic routes.
What specific are you designing for (e.g., highway, park, residential street)? Section B specifically covers lighting for tunnels and
For engineering consultants and developers, achieving PR-402 compliance requires a structured design submission process to the relevant municipal authorities:
Al Reem Island Ring Road (2.5 km, 3 lanes each direction, 80 km/h design speed). 4500K | Non-sustainable
Prior to PR-402, fragmented design approaches led to inconsistent illumination, light pollution, and excessive energy consumption. This manual standardises lighting practices across streets, parks, pedestrian walkways, and public plazas, balancing modern infrastructural demands with environmental stewardship. Core Objectives of the PR-402 Manual
| Mistake | Consequence | Solution | |---------|-------------|----------| | Using European EN 13201 without modifications | Immediate rejection | Overlay Abu Dhabi-specific uniformities (higher Uo) | | Ignoring vertical illuminance at crosswalks | Safety hazard; failed inspection | Add dedicated pedestrian lighting arms or mid-block poles | | Selecting CCT >4500K | Non-sustainable; high insect swarms | Cap at 4000K for roads; 3000K for parks | | Pole base not breakaway on highways | Life safety risk; legal liability | Use slip-base or frangible couplings per ASTM F2656 | | No dimming schedule | Energy waste; non-compliance with Estidama | Submit a 24-hour dimming profile (e.g., 100% from 7 PM-11 PM; 50% from 11 PM-5 AM) |
