Project Background

Reference AC street lighting deployment in Vietnam (2024) using 6m poles and 50W LED luminaires for secondary town roads. Layout assumptions and deliverables can be aligned to EPC review scope on request.
Technical Configuration (Typical Range)
220–240VAC, 50Hz input with surge protection (typ. 10kV) and IP66 outdoor rating
Typical mounting: 6 m poles with 50 W LED, spacing 25–35 m based on road width and targets
Optics: IES Type II / Type III selected by roadway geometry (IES files on request)
Controls: photocell dusk-to-dawn with programmable dimming profiles (optional)
Documentation aligned to EPC review scope: BOQ mapping notes, drawings, and layout inputs (as required)

Scope & Assumptions

A concise summary of what this reference covers and the verification inputs behind it.
Scope (Secondary Town Roads)
  • Coverage: AC street lighting reference deployment in Vietnam (scope-based segments)
  • Use case: EPC / tender workflows requiring verifiable assumptions and auditable notes
  • Deliverables referenced: IES photometry + BOQ notes (on request)
  • Configuration approach: 6m poles with 50W baseline, layout tuned to road width and targets
Verification Inputs (Assumptions Documented)
  • Pole height: 6 m (reference)
  • Spacing: layout-dependent (typ. 25–35 m), documented per section
  • Optics: IES Type II / Type III selected by road width (IES files on request)
  • Targets: maintained lux & uniformity per project brief (scope-based)
  • Controls: photocell dusk-to-dawn with optional dimming profile (documented)
Detailed verification inputs can be shared in a redacted pack or under NDA for tender review.

Photos & Acceptance Notes

Field photos confirm the deployment is real. The notes below summarize typical site acceptance checks used by EPC teams to reduce rework and sign-off risk.
Acceptance Notes (Typical)
✓ Bracket / Arm Interface
Verified against drawings (spigot size, orientation, fasteners).
✓ Wiring & Polarity
Checked before commissioning; glands sealed and connectors secured.
✓ Controller Label / ID
Recorded for traceability (batch/serial).
✓ Pole Verticality & Base
Checked after installation (base fastening).
✓ Dimming Profile
Applied and verified with timestamps (log/screenshot).
✓ Lux Spot-Check (Optional)
Performed on a representative section.
Tip: Full checklist and traceability tables can be shared in a redacted pack (NDA available).

FAQ (Tender & Verification)

Quick answers to common EPC / tender questions for this reference.
What documents can be shared for tender submission?
Typical items include datasheets and drawings, BOQ mapping notes, and (when required) IES/LDT photometric files and layout outputs. The pack can be aligned to the reviewer checklist and declared assumptions.
Do you provide IES files and layout assumptions for verification?
Yes. Model-matched IES/LDT files can be provided on request for optics verification. Layout assumptions (pole height, spacing intent, road width, targets) can be documented for EPC review.
What AC input information is needed for compliance?
Provide grid voltage and frequency (typically 220–240VAC, 50Hz), protection requirements, and any local standards referenced in the tender. These inputs help confirm driver compatibility and protection scope.
How is the 6m / 50W configuration applied across different road segments?
This reference uses 6 m poles with 50 W luminaires as a baseline. Final spacing and optics are selected by road width and maintained lux targets, and are documented per section when required by the scope.
What inputs do you need to propose a similar deployment?
Country/city, road type and width, pole height preference, quantity, operating hours and dimming intent, and any targets (lux/uniformity) if specified. If available, share the BOQ/spec so deliverables can be matched to the reviewer scope.
