• Provide as-built drawings, control diagrams, commissioning results, spare parts, and a maintenance schedule (lamp/lumen maintenance replacement thresholds, cleaning intervals).

The PR 402 Abu Dhabi Lighting Design Manual (Version 3.0, July 2021) acts as the primary regulatory document for infrastructure lighting, focusing on energy efficiency and sustainability. It defines stringent standards for LED color temperature, durable materials, and specific lighting classes for roadways and tunnels to enhance safety and reduce power consumption.

• LED luminaires as the default light source.
• Adaptive lighting (dimming during off-peak hours, e.g., 11 PM to 5 AM).
• Use of photovoltaic (PV) systems where feasible.
• Reduction of Light Pollution (full-cutoff optics to keep light on the road, not the sky).

10. Maintenance Requirements

• Lamp Lumen Depreciation (LLD): Design must use L70 at 100,000 hours (LED).
• Luminaire cleaning: Biannual for roadways; quarterly for tunnel/pedestrian zones.
• Re-lamping: Group replacement at 80% of rated life or as per telemetry data.

Safety & Visibility: Facilitating immediate and accurate visibility for night-time motorists and pedestrians.
