Why a written specification matters
Rechargeable lighting combines mechanical, electrical, optical and packaging decisions. A product image is not a complete specification. Before placing an order, the buyer and factory should approve a version-controlled document that identifies components, performance targets and test methods.
1. Which battery cell and pack configuration is used?
Ask for rated capacity, cell supplier or grade, protection circuit, cycle expectations and replacement approach. Battery claims should refer to the approved production sample, not a generic product family.
2. How is runtime tested?
Record brightness, light mode, ambient temperature, starting charge and the definition of end-of-runtime. A single maximum number without a test condition is difficult to compare.
3. What is the real LED power?
Rated power affects brightness, heat and battery life. Confirm whether the number describes LED power, system input or adapter output.
4. What charging method is supplied?
Review the dock, cable, connector, adapter and charge indicator. Test misalignment, repeated insertion and the ease of use for hotel or retail staff.
5. Can the lighting body be serviced separately?
A detachable product is easier to charge, but buyers should also understand which parts can be replaced: battery, dock, remote, wall holder or complete light body.
6. How does the mounting system prevent movement?
Slim vertical forms highlight small alignment errors. Confirm screw spacing, anti-rotation features, wall anchors and installation tolerances.
7. Which controls are included?
Document button functions, dimming range, light modes, timers, memory and remote behavior. Test whether multiple nearby lights respond unintentionally.
8. How is finish consistency controlled?
Approve physical color samples, gloss, texture and acceptable variation. Metal finishes should be reviewed under both warm and cool light.
9. Which market documents are available?
Compliance requirements depend on destination, battery, adapter, radio functions and sales channel. Ask for a document list early and verify it with the importer or compliance advisor.
10. What quality-control checkpoints are used?
Useful checkpoints may include appearance, assembly, charging, functional control, runtime sampling, remote pairing, packaging drop tests and carton inspection. The final plan should match the product risk.
11. What is included in OEM packaging?
Confirm retail box structure, instructions, labels, barcode placement, accessories and protective materials. Battery products also require transport and handling review.
12. How are engineering changes controlled?
Suppliers should not change battery, LED, driver, charging interface or finish without approval when those changes affect performance or compliance. Agree on a written change-notification process.
Recommended sourcing sequence
- Share target market, application, quantity and price architecture.
- Receive a reference SKU sheet and sample.
- Test runtime, charging, controls, mounting and finish.
- Approve packaging and compliance documents.
- Lock the production specification and QC checklist.
- Run a pilot order before scaling.
