Officially titled "Public Realm Lighting Design Manual (PR 402)," this guideline is the definitive technical and aesthetic standard issued by the Department of Municipalities and Transport (DMT), formerly known as the Abu Dhabi Urban Planning Council (UPC). Whether you are a lighting designer, electrical engineer, contractor, or facility manager, mastering PR 402 is non-negotiable for obtaining design approvals and permits. | Road / Area Type | Average Maintained
| Zone | Name | Description | Max Illuminance (Pedestrian) | |------|------|-------------|------------------------------| | LZ0 | Protected | Dark sky reserves, ecological sanctuaries | 1 lux | | LZ1 | Rural | Low-density villages, desert roads | 5 lux | | LZ2 | Suburban | Residential communities, local parks | 10 lux | | LZ3 | Urban | Commercial centers, mixed-use boulevards | 20 lux | | LZ4 | High-Activity | Downtown Abu Dhabi, Corniche, major squares | Up to 50 lux | or facility manager
By following this guide—respecting zoning, choosing warm-color LEDs, prioritizing uniformity and glare control, and documenting every calculation—you can fast-track approvals, avoid costly rework, and contribute to Abu Dhabi’s vision of a world-class luminous identity.
