Production Standards
At Yuliang LED, quality is our core promise. To deliver high-performance LED products that compete on the global stage, we have established a rigorous, scientific, and internationally-aligned quality assurance system.
Our operational excellence is rooted in strict adherence to globally recognized management standards, including ISO 9001:2015 and IATF 16949. This ensures that every critical step—from raw material procurement and manufacturing to process control and final pre-shipment testing—is systematically managed, standardized, and fully traceable. In our dedicated white light production zone, we go a step further by rigorously implementing the U.S. Energy Star IES LM-80 standard. We conduct long-term verification on key performance metrics such as lumen maintenance and chromaticity shift, guaranteeing outstanding efficacy, color consistency, and extended lifespan in all application environments.
Yuliang LED's Quality Management Team ensures superior product quality through a series of simulated real-world condition tests. By conducting rigorous environmental simulations—such as thermal shock, corrosion resistance, and climate tests—the team validates product durability and performance stability, delivering long-term reliability for global customers.
