| Acrylic Material Quality | Optical clarity, UV resistance, impact strength, sheet consistency, and suitability for outdoor exposure. | Outdoor-grade cast or extruded acrylic with documented thickness tolerance and UV-stability data. | Material technical data sheet, thickness records, color samples, and weathering-test documentation. | 12% |
| Fabrication Precision | CNC routing, laser cutting, thermoforming, edge finishing, bonding, and dimensional repeatability. | Documented production tolerances, consistent seams, smooth edges, and repeatable fit across batches. | Inspection reports, approved production drawings, first-article samples, and dimensional checklists. | 12% |
| LED Efficiency | Luminous output, power consumption, thermal management, bin consistency, and light-distribution uniformity. | System efficacy commonly targeted around 80–130 lm/W, subject to sign design, color, optics, and operating conditions. | Integrating-sphere data, electrical test results, module specifications, and illuminated sample inspection. | 12% |
| Illumination Uniformity | Hot spots, dark areas, edge brightness, viewing angle, and consistency between sign sections. | Even illumination at normal viewing distance, with no visible LED spotting under specified conditions. | Illuminated mock-up, lux-map images, viewing-distance test, and approved color-temperature sample. | 10% |
| Electrical Safety | Power supplies, wiring, grounding, insulation, over-current protection, and service accessibility. | Electrical design aligned with the destination market’s applicable sign, low-voltage, wiring, and safety requirements. | Circuit diagrams, component certificates, dielectric-strength tests, grounding checks, and conformity documentation. | 12% |
| Ingress Protection | Protection against dust and water for outdoor housings, modules, connectors, and power components. | IP65 or higher for suitably designed outdoor sign assemblies where the installation environment requires it. | IP test report for the relevant assembly, enclosure drawings, drainage details, and installation instructions. | 10% |
| Quality Management | Incoming inspection, process control, final inspection, nonconformance handling, and traceability. | A documented quality-management system, preferably independently audited to ISO 9001 where applicable. | Current certificate, audit scope, inspection plan, corrective-action records, and batch traceability samples. | 10% |
| Production Capacity | Available fabrication equipment, skilled labor, assembly space, peak-season capacity, and subcontracting dependence. | Capacity demonstrated through comparable-size projects and a documented production schedule. | Factory audit, equipment list, capacity plan, staffing information, and sample project schedule. | 8% |
| Lead Time Reliability | Engineering approval, sample production, material procurement, manufacturing, packing, and dispatch performance. | A clearly defined schedule with milestone dates and historical on-time delivery records. | Project timeline, capacity reservation, procurement plan, and anonymized delivery-performance records. | 6% |
| Warranty & Service | Warranty duration, LED and power-supply coverage, spare parts, repair process, and response time. | Written coverage with clearly stated exclusions; many commercial projects specify 2–5 years depending on components and use. | Warranty document, spare-parts list, service-level procedure, and replacement-cost schedule. | 5% |
| Packaging & Logistics | Protection from scratching, impact, moisture, vibration, and deformation during international transport. | Custom protective packaging with moisture control, shock protection, labeling, and shipment inspection. | Packaging drawings, drop-test approach, loading photos, export documents, and insurance terms. | 4% |
| Total Cost of Ownership | Purchase price, installation, energy consumption, maintenance, replacement parts, and disposal considerations. | Comparison based on total installed cost and estimated operating cost rather than purchase price alone. | Itemized quotation, power calculation, maintenance plan, expected component life, and lifecycle-cost model. | 9% |
