| 1 | Light Quality | CRI ≥ 95 and TLCI ≥ 95 | Request an independent photometric test report for the final model. | High color-rendering performance helps preserve accurate skin tones, product colors, and video detail. |
| 2 | Color Temperature Range | At least 3,200–5,600K; wider ranges such as 2,700–6,500K are more versatile. | Check the measured CCT at minimum, middle, and maximum settings. | Adjustable CCT allows the light to match warm indoor lighting, daylight, and mixed environments. |
| 3 | Dimming Performance | Smooth adjustment from approximately 1% to 100% without visible flicker. | Test brightness using a camera at different shutter speeds and dimming levels. | Stable dimming is essential for close-up video, livestreaming, and photography. |
| 4 | Flicker and Electrical Safety | Low-flicker operation with appropriate electrical protection for the target market. | Request flicker test data and applicable safety documentation for the power supply. | Reduces rolling-band artifacts, eye strain, overheating risks, and compliance problems. |
| 5 | Illuminance and Beam Control | Measured lux values should be provided at a stated distance, commonly 0.5 m or 1 m. | Compare a calibrated lux-meter report using the same distance and settings. | Standardized measurements make competing models easier to compare accurately. |
| 6 | LED and Thermal Design | Aluminum heat dissipation, stable LED boards, and documented continuous operating time. | Conduct a continuous-load test and inspect temperature rise after extended operation. | Effective thermal management supports consistent brightness and longer service life. |
| 7 | Mechanical Construction | Rigid housing, reinforced mounting points, stable adjustment joints, and a secure diffuser. | Inspect samples and perform repeated tilt, rotation, and mounting-cycle tests. | Durable construction lowers damage rates during studio use and international shipping. |
| 8 | Customization Capability | Support for packaging, accessories, manuals, firmware or control functions, and product appearance changes. | Request a written customization list, tooling terms, sample process, and production lead time. | Clear engineering capability helps prevent delays and inconsistent specifications. |
| 9 | Quality-Control System | Documented incoming-material inspection, assembly checks, aging tests, and final inspection. | Ask for inspection records, sampling plans, defect criteria, and corrective-action procedures. | A documented process provides better consistency than a sample-only evaluation. |
| 10 | Export and After-Sales Support | Clear warranty terms, spare-parts availability, export packaging, and responsive technical support. | Review the sales contract, warranty policy, replacement process, and shipping documentation before ordering. | Reliable support reduces downtime and protects the total cost of ownership. |
