| 1 | Product Application Compatibility | Confirm the light is designed for the intended hood, canopy, kitchen, commercial, or industrial application and operating environment. | Different environments require different optical distributions, mounting methods, thermal designs, and protection levels. | Product datasheet, installation drawing, application photos, mounting instructions, and environmental operating limits. | 12% |
| 2 | Ingress Protection | Use an IP rating appropriate to the installation. IP65 means dust-tight protection and protection against water jets according to IEC 60529. | Hood lights may be exposed to steam, grease, splashes, dust, or frequent cleaning. | Test report identifying the exact model, test standard, laboratory, test date, and rated configuration. | 12% |
| 3 | Electrical Safety and Compliance | Verify compliance with the destination market’s applicable electrical, electromagnetic-compatibility, and restricted-substance requirements. | Regulatory compliance reduces customs, installation, liability, and product-recall risks. | Declaration of conformity, safety test reports, EMC reports, restricted-substance declaration, and technical file summary. | 14% |
| 4 | Photometric Performance | Compare delivered lumens, wattage, efficacy, beam angle, color temperature, color rendering, and lumen maintenance under the same test conditions. | Nominal wattage alone does not show how much useful light reaches the working area. | LM-79 or equivalent photometric report, IES/LDT file, integrating-sphere data, and independent test results where available. | 12% |
| 5 | Thermal Management | Look for a properly engineered heat sink, suitable operating-temperature limits, and stable performance after thermal testing. | Excessive heat accelerates LED depreciation and can shorten driver and capacitor life. | Thermal test report, LED case-temperature data, internal layout images, and rated ambient-temperature range. | 10% |
| 6 | LED Driver Reliability | Check input-voltage range, power factor, total harmonic distortion, surge protection, dimming compatibility, and replacement availability. | The driver is a critical component affecting flicker, energy use, safety, and service life. | Driver datasheet, electrical test report, surge-rating information, flicker data, and approved component list. | 10% |
| 7 | Materials and Cleanability | Prefer materials and finishes that are suitable for the installation, easy to clean, corrosion-resistant where necessary, and compatible with approved cleaning procedures. | Grease, moisture, detergents, and repeated cleaning can damage unsuitable housings, lenses, seals, and coatings. | Material specifications, coating or corrosion test data, cleaning guidance, gasket information, and lens material details. | 9% |
| 8 | Quality-Control System | Require documented incoming inspection, assembly inspection, aging or burn-in procedures, final testing, and traceability. | A repeatable quality system is more dependable than a single sample inspection. | Quality manual, inspection checklist, sample test records, calibration certificates, corrective-action records, and batch traceability process. | 9% |
| 9 | Customization and Production Capability | Assess capability for color temperature, lens, mounting, cable, connector, voltage, dimming, labeling, packaging, and regional documentation requirements. | Global projects often require installation-specific configurations rather than one standard model. | Current product range, production-flow description, sample-development schedule, minimum order quantity, and change-control procedure. | 6% |
| 10 | After-Sales Support and Total Cost | Evaluate warranty terms, spare-parts policy, response time, replacement process, lead time, packaging, payment terms, and total delivered cost. | A low purchase price may become expensive if failures, delays, spare parts, or technical support are not managed. | Written warranty, service-level terms, spare-parts list, failure-analysis procedure, production lead time, and landed-cost quotation. | 6% |
