Material, height and mounting
Send elevations, surface material, building height, mounting position, setback and access constraints.
Saudi & GCC / hotel facade contractors
A focused supply route for hotel facade contractors and hospitality project teams: shortlist wall washers and linear luminaires, define the mock-up, request model evidence and send one controlled BOQ.

RFQ inputs
These inputs reduce the number of clarification rounds between the contractor, lighting designer, supplier and mock-up team.
Send elevations, surface material, building height, mounting position, setback and access constraints.
State the target effect, viewing distance, beam direction, CCT, colour consistency and DMX, DALI or switching requirement.
Describe heat, dust, rain, coastal salt, drainage, cable routing, driver location and the maintenance method.
List quantities by elevation, mock-up and sample dates, required IES or drawings, certificates, packing and delivery destination.
Product and evidence paths
Use catalogue models as candidates, then confirm the exact configuration and evidence package for the named project.
Compare visible wall-washer and linear model routes for grazing, washing and outline tasks.

Open this routeEvidence boundary. Topeng-controlled production and qualified partner-factory integration are separate routes; an item is identified as Topeng-produced in the quotation or submittal only when that record states it. For every complementary item, the responsible manufacturer and document owner remain named in the RFQ record. Catalogue product views identify products, not completed Topeng hotel projects. Any named project reference, approval or performance claim requires separate permission-cleared evidence.
Common questions
Practical answers for product selection, quotation and project coordination.
Send the elevation, facade material, building height, mounting position, setback, target effect, beam preference, control protocol, exposure, quantities, required documents and target dates.
No. Product images identify authorized catalogue models. Any application concept is labelled and is not project evidence; named project references require separate permission-cleared evidence.
State the mock-up zone, viewing distances, surface material, mounting geometry, candidate optics, control scenes, acceptance criteria and required sample date in the RFQ.
