Before PR 402, lighting projects in Abu Dhabi often suffered from inconsistent illumination, excessive energy use, and light pollution. The manual was introduced to:
Defines classes such as M2 and M4 based on luminance levels (e.g., 1.0 to 1.5 cd/m²) and uniformity ratios tailored to vehicle speed and road type.
The PR 402 manual was established to transform Abu Dhabi's nightscape while adhering to Sustainable Development Goals (SDGs) and the Abu Dhabi Vision 2030. The document balances technical performance with environmental stewardship through several key objectives:
| Violation | Consequence | Solution | |-----------|-------------|----------| | Using 5000K LEDs | Immediate rejection | Only 3000K or 4000K max, with justification. | | Insufficient uniformity (Uo < 0.35) | Safety hazard, non-compliance | Increase pole spacing or add secondary luminaires. | | Up-lighting on villa façades | Light trespass, neighbor complaints | Use shielded wall-washers or downward grazing fixtures. | | Ignoring controls (no dimming) | Fails Estidama review | Specify 0–10V dimmable drivers and programmable schedule. | | Using non-IP65 fixtures | Dust ingress, early failure | Require IP66 for horizontal or exposed luminaires. |
