Leno lighting quality control expertise
The lighting industry is continuously innovating to satisfy consumers demands, improving design aesthetics, power consumption, environmental friendliness, and integrating with other technologies. Poor lighting manufacturing practices can result in fire hazards and harm to consumers, causing damage to an organization. Importers and retailers of lighting must implement a comprehensive quality control program to prevent quality and safety risks, and stay competitive.
LENO offers product-specific lighting quality control services in China & Asia. Our expertise extends to outdoor lights, indoor lights, ceiling lights, chandeliers, table lamps, floor lamps, desk lamps, lighting controls, as well as LED bulbs and conventional bulbs.
LENO assesses both the suppliers manufacturing skills and the manufactured products quality, including the mechanical and physical properties of your lighting, and compliance with relevant standards. These include US, EU and numerous other standards.
lighting quality control approach
leno technical engineers take into account your quality objectives and unique product specifications, to build a customized lighting inspection checklist.
leno inspectors verify the mass production workmanship based on your acceptable quality limits (aql), provide an overview of the finished goods’ quality, and highlight the key production areas requiring improvement. we also perform on-site tests and assess compliance with your product’s specifications and reference samples.
some tests on lighting require a controlled environment to ensure compliance with the standards and regulations. leno inspectors pick products from each lot and forward them to an accredited laboratory for testing.
leno goes further than the average quality inspection service in china & asia by assisting you to set up, manage, and monitor a customized surveillance program. we use our extensive product knowledge, along with kpis from our leading edge online technology, to identify and help implement improvements to optimize your supply chain efficiency.
