Why IES/LDT is non-negotiable

  • High mast performance is defined by distribution + aiming + spacing, not “wattage charts”.
  • IES/LDT + simulation is the only defensible way to verify targets and uniformity.
  • Photometrics also reveals glare and spill risk in yards, ports, and stadiums.

Inputs required (copy/paste)

Project location:
Application (highway / yard / port / industrial / stadium):
Area geometry (road width or area dimensions):
Pole height (m):
Pole spacing / layout constraints:
Mounting positions (single-side / double-side / corner / perimeter):
Target illuminance (Avg lux):
Uniformity target (if specified):
Optics preference (Type III / IV / V / Not sure):
CCT / CRI:
Glare / spill constraints (nearby roads/houses):
Environment (coastal / desert / humid / normal):

Deliverables checklist

  • IES/LDT files for each luminaire option + optic.
  • Simulation files/outputs (DIALux/AGi32): layout, calculation grid, results tables.
  • Layout proposal: pole heights, spacing, aiming notes, assumptions clearly stated.
  • Targets: average lux + minimum + uniformity (define which uniformity metric is used).
  • Glare/spill notes: shields/visors/tilt limits if required.
  • Lista de materiais: luminaires, brackets, wiring, accessories.

Métricas de aceitação (o que mostrar)

  • Average illuminance (Avg lux)
  • Minimum illuminance (Min lux)
  • Uniformidade (Min/Avg or Avg/Min — specify which is used)
  • Calculation grid and area boundaries
  • Aiming/tilt limits to control glare/spill
  • Pressupostos: pole height, spacing, mounting, optics, CCT, depreciation factor (if used)

Cláusulas da solicitação de cotação (copiar/colar)

  • O fornecedor deve fornecer IES/LDT files for the proposed luminaire/optic.
  • O fornecedor deve fornecer um DIALux/AGi32 layout proposal with Avg lux, Min lux, and uniformity results.
  • All assumptions must be stated: pole height, spacing, mounting arrangement, optics type, CCT/CRI, glare/spill constraints.
  • Bids without IES/LDT + simulation outputs are non-compliant.

Armadilhas comuns em licitações

  • “Wattage comparison” without optics/IES = not comparable.
  • Layouts that omit uniformity or hide assumptions.
  • Using a different optic in simulation vs the quoted product.
