DIALux / Relux Simulation Outputs for EPC & Tenders

Submission-ready calculation reports with stated assumptions: MF, tilt, spacing, and geometry. Typical response within 24 hours after receiving complete inputs.

Input Checklist


  • Road type / application (road, yard, campus, court)

  • Targets (maintained lux + uniformity requirement)

  • Mounting height + pole spacing (or layout assumption)

  • Road width / lanes / median (or CAD / map pin)

  • Tilt / arm length / aiming notes (if any)

  • Power mode (solar / grid) + constraints

  • Submission checklist (client / consultant requirements) 
!
Why Inputs Matter
Most tender rejections come from unstated assumptions (height, spacing, MF, tilt). Complete inputs make the simulation reviewable, defensible, and faster to approve.
  • Avoid optics–spacing mismatch
  • Reduce redesign cycles
  • Speed up approvals

FAQ (DIALux / Relux Simulation for Tenders)

Quick answers to common EPC and tender questions—inputs, assumptions (MF/tilt/spacing), deliverables, and file traceability. If your submission has special rules or NDA requirements, tell us in the form and we’ll align.
What inputs do you need to start a DIALux/Relux simulation?
At minimum: road/area type, target maintained lux and uniformity, mounting height, spacing assumptions, arrangement (single/double-side, staggered/opposite), and any tender submission checklist. If you have CAD or a site sketch, attach it for faster alignment.
Do you provide maintained results or initial results?
We provide maintained results by default. The report states the maintenance factor (MF/LLF) used and the key assumptions that affect compliance (tilt, spacing, geometry, and photometry reference).
Can you share a sample DIALux/Relux report?
Yes. We can share a redacted sample (client/project details removed) showing the report structure, assumptions page, results tables, and layout evidence. If your tender requires NDA, we can share under NDA.
Do you provide matching IES/LDT files with the report?
Yes, when required. We can provide the matching IES/LDT files used for the simulation and list the photometry filename/revision in the report for traceability.
What if my project has multiple road sections or zones?
We can structure outputs by zones (e.g., Section A/B, lane/sidewalk) with separate tables and layout screenshots. Provide zone boundaries or a simple sketch so areas are labeled consistently in the report.
