A minimum clear area of 1000mm must be maintained around the pole center.
By assigning strict limits on Upward Light Ratio (ULR) and Intensity (I) for each zone, the manual provides quantifiable metrics for developers. This removes subjectivity from the approval process, forcing engineers to design lighting that stays within its intended boundaries.
To combat blue-rich light pollution (which scatters most in the atmosphere), PR 402 imposes aggressive CCT caps:
All architectural lighting designs must include a showing that no light spills above the horizontal plane. pr 402- abu dhabi lighting manual
The , officially the Abu Dhabi Lighting Manual , is the primary design standard for lighting infrastructure within the Emirate of Abu Dhabi. Managed by the Department of Municipalities and Transport (DMT) , the manual provides comprehensive technical requirements for roadway and public space lighting to ensure safety and sustainability. Key Specifications of PR-402 (Version 3.0, July 2021)

Enhancing visibility on roadways and in parking areas for both vehicles and pedestrians.
Ensuring optimal visibility on roadways, pedestrian pathways, and public spaces to reduce accidents. To combat blue-rich light pollution (which scatters most
Abu Dhabi’s Vision 2030 places an immense emphasis on green infrastructure. PR 402 reflects this by enforcing strict environmental guidelines. Luminaire Efficacy
Detailed specifications regarding structural requirements.
Shopping districts, roundabouts, and pedestrian walkways focus on vertical illuminance. This design choice enhances facial recognition and pedestrian security. Color Temperature (CCT) and Rendering (CRI)
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
The PR-402 Abu Dhabi Lighting Manual has been the cornerstone of all exterior lighting projects in the emirate since 2021, governing decisions from product manufacturing to urban planning. Key takeaways include:
