Practical answer
Create one interface register before reviewing separate fixture schedules
Assign each boundary, circuit, control scene, mounting detail and night-time objective to an accountable package. Then control drawing and photometric revisions through one register. This prevents an individually acceptable facade, landscape or tenant submission from creating duplicated brightness, conflicting controls or inaccessible equipment at the shared edge.
Decision matrix
| Site condition | Specification response | Approval evidence |
|---|---|---|
| Facade meets public realm | Assign reflected-brightness, mounting and scene ownership | Interface elevation, calculation revision and responsibility register |
| Tenant frontage meets landlord lighting | Set permitted contribution, hours and control handoff | Tenant criteria, scene matrix and approval workflow |
| Back-of-house meets public route | Separate task visibility from guest-facing brightness | Circuit schedule, shielding detail and maintenance access review |
Selection and verification workflow
- List every package and shared physical boundary.
- Assign drawings, calculations, controls and approvals to named roles.
- Freeze file names, revisions and photometric assumptions.
- Review combined night scenes rather than isolated packages.
- Issue one coordinated close-out register to operations.
Limits and responsibility boundaries
- This guide does not replace authority, code or appointed-consultant review.
- A supplier submittal cannot resolve unassigned architectural or electrical interfaces.
- Road, emergency and life-safety calculations remain outside this procurement guide.
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.
- Coordinated interface register and drawing list.
- Revision-matched photometric files and calculations.
- Circuit, control and addressing responsibility matrix.
- Mounting, driver-location and access details.
- Combined mock-up, snag and close-out records.
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.
