When preparing a design submission for the municipality under PR 402, engineers must compile a detailed technical package. A standard compliance checklist includes:
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.
The manual is divided into several parts to address specific environments: : Lighting for Tunnels and Underpasses. Section C : Roadway and Parking Lighting Poles.

PR-402 is not just a technical guide but a procedural framework: Submissions
Prioritizing high-efficiency fixtures to drastically reduce municipal carbon footprints.
PR 402 provides strict average lux (lx) and uniformity (Uo) values for each road and area type. Unlike Western standards that use maintained lux, PR 402 uses values, which are higher to account for dust depreciation. When preparing a design submission for the municipality
Due to heavy dust storms and coastal humidity, a minimum rating of IP66 is standard for both the optical and gear compartments of luminaires.
The manual strictly regulates Correlated Color Temperature (CCT) to ensure visual comfort and environmental safety:
Class M2/M4, requiring luminance of 1.0 to 1.5 cd/m² (approx. 15–25 lux) depending on traffic volume. Section C : Roadway and Parking Lighting Poles
To reduce long-term maintenance costs for the municipality, PR-402 outlines strict material lifetime expectations:
PR 402 is not merely a technical suggestion; it is a comprehensive regulatory framework designed to govern the implementation of artificial lighting across the Emirate of Abu Dhabi. Its primary objective is to balance the need for functional, safe illumination with the critical imperatives of energy conservation, environmental protection (specifically light pollution), and the preservation of the Emirate’s cultural identity.
