| 1 | Light Quality and Color Accuracy | CRI Ra ≥ 95; preferably include TLCI or TM-30 data for professional video and photography use. | Independent photometric test report, integrating-sphere report, and sample test results. | 20% |
| 2 | Color Temperature Control | Bi-color models should normally cover approximately 2700–6500 K, with stable adjustment and published tolerance. | CCT test data at minimum, maximum, and midpoint settings; dimming and flicker results. | 10% |
| 3 | Illuminance and Power Efficiency | Compare lux at a clearly stated distance, beam angle, input voltage, and power level rather than using wattage alone. | Lux-versus-distance chart, actual power-consumption data, and adapter specifications. | 15% |
| 4 | Flicker and Video Compatibility | Flicker-free performance should be verified across the full dimming range and common camera shutter speeds. | Flicker-index or percent-flicker report, high-speed camera test, and dimming curve. | 10% |
| 5 | Electrical and Product Safety | Products should have test documentation appropriate to the destination market, such as CE, RoHS, FCC, UKCA, or equivalent requirements. | Valid declarations, test reports, labels, user manuals, and safety data for the exact model. | 10% |
| 6 | Thermal Management and Service Life | The manufacturer should document heat dissipation, operating temperature, LED reliability, and continuous-use testing. | Aging-test records, thermal images, LED datasheets, and warranty failure-rate information. | 10% |
| 7 | Mechanical Design and Accessories | Assess housing strength, diffuser quality, mounting compatibility, stand stability, cable design, and control options. | Material specification, load test, tilt-angle range, accessory list, and sample inspection. | 8% |
| 8 | Customization and OEM Capability | Evaluate custom housing, firmware, packaging, color temperature range, connector type, and private-label documentation. | Previous non-confidential project examples, engineering workflow, tooling charges, and sample approval process. | 7% |
| 9 | Quality Management and Production Control | Prioritize traceable incoming inspection, in-process testing, final inspection, calibration records, and corrective-action procedures. | Quality manual, inspection checklist, factory audit, production photos, and batch-test records. | 5% |
| 10 | Commercial Terms and After-Sales Support | Compare MOQ, lead time, payment terms, spare-parts availability, warranty coverage, replacement policy, and response time. | Formal quotation, warranty terms, sample invoice, production schedule, and service-level contact. | 5% |
