| Product Positioning | Contemporary indoor fixtures with clean geometry, neutral finishes, integrated LED options, and space-conscious designs. | A structured range covering pendant lights, ceiling lights, wall lights, track fixtures, linear systems, and decorative task lighting. | Review the current catalogue, technical drawings, finish samples, and project photographs without relying only on promotional images. |
| Light Performance | Clearly stated lumen output, wattage, beam angle, colour temperature, colour-rendering data, and operating life. | Photometric files such as IES or LDT, LED module information, driver specifications, and test reports for the supplied configuration. | Compare declared data with an independent photometric report or a sample tested by a qualified laboratory. |
| Colour Quality | CRI 80+ is common for general interiors; CRI 90+ is generally preferred for hospitality, retail, galleries, and premium residential areas. | Consistent CCT options, stated tolerance, colour-consistency information, and suitable binning documentation. | Request LM-80 or equivalent LED component evidence where relevant, plus sample-to-sample colour comparison. |
| Flicker and Visual Comfort | Low-flicker or flicker-controlled operation is increasingly expected in workspaces, hospitality, and long-duration occupied areas. | Driver information, flicker measurements where available, glare-control options, diffusers, and shielding accessories. | Ask for measured flicker data and inspect the fixture through a high-frame-rate camera only as a preliminary check, not as laboratory proof. |
| Electrical Compatibility | The product should be configured for the destination market’s voltage, frequency, dimming method, plug or wiring practice, and safety requirements. | Input-voltage options, dimming compatibility, wiring diagrams, driver data, surge information, and installation instructions. | Confirm requirements before quotation and test the exact production configuration rather than a visually similar sample. |
| Safety and Compliance | Documentation should correspond to the actual model, voltage, driver, materials, and destination market. | Relevant declarations, safety reports, EMC information, material documentation, and Chinese standards such as GB 7000.1 where applicable. | Check report numbers, product photographs, model descriptions, laboratory details, dates, and scope of coverage. |
| Customization Capability | Useful customization typically includes colour, dimensions, cable length, mounting method, diffuser, light source, and control system. | A defined approval process for drawings, samples, engineering changes, and production sign-off. | Request a written specification sheet and confirm which changes affect tooling, lead time, price, warranty, or compliance. |
| Material and Finish Quality | Contemporary products commonly use aluminium, steel, glass, acrylic, fabric, or engineered polymers, with finish consistency across batches. | Material specifications, finish codes, corrosion or coating information where relevant, and replacement-part availability. | Approve physical samples and define acceptable limits for colour variation, surface defects, alignment, and assembly quality. |
| Wholesale Flexibility | A suitable wholesaler should support mixed models, repeat orders, project quantities, and transparent quantity-based pricing. | Clear MOQ rules, sample policy, carton quantities, spare-part policy, payment terms, and quotation validity period. | Request a line-item quotation that separates product cost, tooling, samples, packaging, testing, and shipping charges. |
| Quality Control | Quality control should cover incoming materials, assembly, electrical safety, lighting performance, appearance, packaging, and final inspection. | Documented inspection criteria, production records, defect classification, corrective-action procedures, and pre-shipment inspection options. | Use an approved inspection checklist and verify random samples before shipment. |
| Packaging and Logistics | Packaging should protect glass, painted surfaces, diffusers, drivers, and projecting components during domestic and international transport. | Export carton specifications, drop or vibration considerations, pallet information, HS-code support, and shipping-document accuracy. | Approve a packed sample or packaging specification and compare carton dimensions with the freight quotation. |
| Lead-Time Reliability | A dependable supplier provides separate timelines for sampling, tooling, production, inspection, and dispatch instead of one generic estimate. | Milestone schedule, production updates, escalation contact, and a documented process for delays or engineering changes. | Compare quoted dates with purchase-order milestones and review performance across repeat orders. |
| Warranty and Service | Warranty duration and coverage should be stated for the complete fixture, LED module, driver, finish, and replacement components. | Written warranty terms, troubleshooting guidance, spare-part availability, claim evidence requirements, and response targets. | Review exclusions such as installation errors, unsuitable voltage, environmental exposure, and unauthorised modification. |
| Sustainability and Documentation | Preference should be given to durable, repairable, replaceable, and efficiently packaged products with transparent material information. | Energy data, product composition, packaging details, recycling guidance, and evidence for environmental claims. | Distinguish measured or certified information from general marketing language and retain documents for project records. |
