Pr 402- Abu Dhabi Lighting Manual Free Today

Understanding the PR 402: Abu Dhabi Lighting Manual The PR 402 - Abu Dhabi Lighting Manual is the definitive technical standard for the planning, design, and installation of public realm and roadway lighting across the Abu Dhabi Emirate. Managed by the Department of Municipalities and Transport (DMT), this manual ensures that street lighting provides uniform visibility, safety, and comfort for motorists and pedestrians alike. Purpose and Scope

Max bracket arm length of 1.5m; max luminaire tilt of 5 degrees from horizontal. Durability pr 402- abu dhabi lighting manual

Main requirements (practical summary)

  • Energy performance: Meet specified illuminance, efficacy, and control targets. Use high-efficiency luminaires (LEDs) and minimize wasted light.
  • Lighting levels & uniformity: Provide target horizontal/vertical illuminance and uniformity ratios per space type (offices, retail, corridors, classrooms, car parks, sports areas). Use task-based targets rather than over-lighting.
  • Color quality: Specify CRI ≥ 80 for most interior spaces; CRI ≥ 90 where color rendering is critical (retail, galleries, medical).
  • Color temperature: Recommend 2700–4000 K depending on function (warmer for hospitality/residential, neutral for offices/healthcare, cooler for sports/exterior security) while considering circadian impacts.
  • Controls & zoning: Mandatory use of zoning, occupancy sensors, daylight dimming, time schedules, and scene control to reduce runtime and maintain comfort.
  • Daylighting & glare: Maximize useful daylighting; provide automatic daylight dimming and glare control (appropriate luminance ratios, shading devices, shielded fixtures).
  • Exterior lighting & light pollution: Limit upward light output; use full cut-off or shielded fixtures, control lumen caps for façades and signage, and set curfews or dimming during late-night hours.
  • Emergency & safety lighting: Maintain required emergency illuminance, battery backup duration, signage luminance, and periodic testing protocols.
  • Controls interoperability: Prefer open protocols (DALI, BACnet) and provide integration points for building management systems (BMS).
  • Commissioning & verification: Require pre- and post-installation lighting calculations, on-site measurements, and a commissioning report verifying compliance with illuminance, uniformity, efficacy, control sequences, and emergency functions.
  • Maintenance & documentation: Provide maintenance plans, replacement schedules, lumen depreciation data, spare parts list, as-built lighting layout, luminaire schedules, and control logic diagrams.
  • Metering & monitoring: Install metering for lighting circuits and provide energy-use reporting capability; incorporate fault reporting where possible.
  • Occupant comfort & glare metrics: Use Unified Glare Rating (UGR) or equivalent thresholds for visual comfort in offices and workspaces.
  • Adaptive & smart strategies: Encourage tunable white, circadian lighting strategies in healthcare/education, and demand-responsive dimming for large exterior installations.

Part 2: Core Technical Requirements of PR 402

2.1 Illuminance Levels (Lux Tables)

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 initial lux values, which are higher to account for dust depreciation. PR-402 is not just a technical guide but

Typically M2 or M4 based on roadway type. M2 targets 1.3–1.5 cd/m² (approx. 20–25 lux); M4 targets 1.0 cd/m² (approx. 15 lux). LED Standards
