Generally restricted to warm or neutral white (2700K to 4000K) to create an inviting atmosphere. 3. Structural and Facade Lighting
For engineers and contractors, here is the practical workflow:
Enhancing architectural landmarks while preserving the natural night sky. 2. Key Technical Standards and Specifications pr 402- abu dhabi lighting manual
For consultants and engineers, the mandatory Estidama PBRS manual is the essential companion to the Dark Sky Policy. It provides:
The manual strictly regulates Correlated Color Temperature (CCT) to ensure visual comfort and environmental safety: Generally restricted to warm or neutral white (2700K
Establishes precise luminance levels to optimize immediate, glare-free visibility for motorist and pedestrian corridors alike.
Submit detailed lighting design reports, calculation files, and single-line electrical diagrams to the DMT or local municipality for review and formal approval before construction begins. Conclusion meaning that after 50
: Includes procedures for Day-1 calculation outputs and harmonic measurements to ensure real-world performance matches the design. Why It Is Useful
The PR-402 Lighting Manual was developed to support the , the emirate's strategic framework for economic, social, and urban development. The manual’s primary objectives are to:
Luminaires used in these configurations must provide top-tier ingress protections—typically —paired with robust impact defenses ( IK08 to IK10 ) to successfully withstand intense ambient sand, dust, and coastal humidity. Color Rendering Index (CRI) minimums guarantee accurate spatial awareness, while correlated color temperatures (CCT) are restricted to suppress disruptive blue-light wavelengths. Structural Engineering and Foundation Rules
at 50,000 hours, meaning that after 50,000 hours of continuous operation, 90% of the luminaires must still retain at least 90% of their initial light output.
