Practical answer
Review the complete installed path, not the luminaire in isolation
Trace the offered unit from structural fixing through cable route, junction, driver enclosure, control address and maintenance access. Match corrosion and ingress evidence to each exposed interface, then commission aiming and scenes against recorded references. Structural, traffic-safety, navigation and road-lighting duties remain with appointed project professionals.
Decision matrix
| Site condition | Specification response | Approval evidence |
|---|---|---|
| Exposed parapet or structural edge | Coordinate fixing, vibration, finish compatibility and cable protection | Approved detail, structural review and material schedule |
| Driver and junction enclosure | Separate water, heat and service-access risks | Enclosure layout, ingress evidence and thermal statement |
| Long linear or dynamic scene | Define addressing, segmentation, fail state and aiming references | Topology, address list and commissioning record |
Selection and verification workflow
- Zone exposure, movement, access and observer positions.
- Trace fixing, cable, junction, driver and control paths.
- Match materials and protective systems to declared exposure.
- Commission aiming, addresses, scenes and fail behavior.
- Hand over access, spares, inspection and replacement records.
Limits and responsibility boundaries
- Structural fixing and vibration approval require the appointed bridge team.
- Traffic, road-safety and navigation lighting are outside this architectural guide.
- An IP rating alone does not prove corrosion resistance or installed-joint performance.
Evidence to request before approval
Treat a model name or brochure statement as a starting point. The supporting files must describe the same offered optic, construction, driver, finish and control configuration.
- Structural interface and fixing detail.
- Cable, gland, junction and driver-enclosure layout.
- Material, coating, fastener and corrosion evidence.
- Photometric file, aiming schedule and glare review.
- Address list, commissioning results and maintenance plan.
RFQ input checklist
Comparable quotations require the same site inputs, document scope, exclusions and commercial assumptions from every bidder.
- Country, city, project stage, site plan and application-zone schedule.
- Quantities, mounting details, voltage, CCT, optic and control requirements.
- Heat, dust, salt, water, irrigation, public-access and maintenance exposure.
- Datasheet, photometric file, drawing, material, finish and test-evidence requirements.
- Sample, mock-up, packing, spare-parts, delivery and warranty expectations.
