Quality Control
Incoming Quality Control (IQC)
As the first line of defense for lighting quality, KML conducts rigorous inspections on core components such as lamp body heat sinks, driver power supplies, light sources, and lenses to ensure that raw materials meet standards from the source.
- Qualification review:
We only accept materials that meet international or national authoritative certification standards and provide relevant test reports; at the same time, we conduct annual process compliance audits of core suppliers to ensure the stability of material quality from the source of cooperation. - Parameter verification:
According to the BOM list, the model, specifications and quantity of materials are checked to prevent problems such as "wrong materials" and "insufficient materials"; the deviation of key parameters such as the thermal conductivity of the heat sink and the light source from the design parameters is strictly controlled within a reasonable range to ensure the compatibility of components. - Functional testing:
As per the order requirements, we conducted tests on the color temperature, brightness, color rendering index, and wavelength of the light source, and on the power, current, and voltage of the driving power supply. We also conducted additional waterproof tests on the waterproof power supply to verify that its waterproof performance met the standards.
In-Process Quality Control (IPQC)
Industry-standard testiIn the lighting fixture production process, KML follows the ISO 9001 quality management system, setting up multiple inspection points to ensure early detection and rectification of potential problems in the process.ng equipment for optical, electrical, and environmental validation.

By using a photometer and integrating sphere tester to test luminaires, essential optical values such as light intensity distribution curve, luminous flux, color temperature, SMCD, and color rendering index can be accurately measured, allowing for a precise understanding of the luminaire's various performance characteristics.
Certification Strength
With the robust guarantee of a rigorous quality control system throughout the entire process, our products not only pass the national CQC and CCC mandatory certifications, but are also compatible with multiple international certifications such as ETL, DLC, ENEC, TUV, SAA, CB, CE, and RoHS, basically meeting the requirements of different domestic and international markets and giving customers greater peace of mind.
