Lighting Manual — Pr 402- Abu Dhabi
After installation, a photometric field test is mandatory. The contractor must provide a test report using a calibrated luminance meter, comparing five random points to the design predictions. Tolerances: ± 7% for L avg; ± 10% for E min.
By enhancing energy efficiency and reducing light pollution, compliance with PR-402 is crucial for projects aiming for higher Estidama Pearl Rating System certification. Conclusion
All architectural lighting designs must include a showing that no light spills above the horizontal plane. pr 402- abu dhabi lighting manual
Lighting designs must adhere to specific technical criteria, including minimum average illuminance ( Emcap E sub m ) and luminance ( Lvcap L sub v
The official PDF file, "PR-402.pdf", is made freely available by the Department of Municipalities and Transport (DMT), allowing all stakeholders to access and consult the official regulations. The manual was officially launched in late 2014, with the 3rd edition released in 2021.

PR 402 is built on three pillars, which every designer must internalize:
A minimum clear area of 1000mm is required on either side of the pole center, which should be finished with hardscape or gravel. By enhancing energy efficiency and reducing light pollution,
| Requirement | Compliant (Y/N) | Remarks | |-------------|----------------|---------| | E_avg meets road class | | | | U0 ≥ 0.30 / 0.35 | | | | TI ≤ 15% | | | | CCT within 3000K–4000K (road) | | | | ULR = 0% | | | | Spill light < limit | | | | Curfew dimming enabled | | | | IP66 + IK08 | | | | Dialux report attached | | |
Even experienced designers make mistakes. Here are the most frequent PR 402 rejections:
PR 402 does not operate in a vacuum. A compliant design must also satisfy:
