This is a large-scale electrical and electronic testing laboratory located in Southeast Asia, specializing in quality inspections of imported and exported goods. With its professional testing capabilities and strict quality standards, the laboratory enjoys a strong reputation within the industry.
The laboratory first learned about LISUN through one of our long-term clients in Vietnam. They developed a strong interest in LISUN’s integrating sphere systems and began exploring the products further. After browsing LISUN’s official website, they expressed keen interest in the LPCE-2 High Precision Spectroradiometer Integrating Sphere System and immediately inquired about its pricing.
As a professional testing laboratory, their test samples vary widely in size. To meet their diverse requirements, we recommended the LPCE-2 (LMS-9000C) High Precision Spectroradiometer Integrating Sphere System, equipped with a 2-meter-diameter integrating sphere. After consulting with our technical team and confirming all the technical specifications, the customer quickly placed their order.
Once the system was delivered, the customer expressed high satisfaction with LISUN’s product quality and after-sales service. This smooth initial cooperation laid a solid foundation of trust between the two parties.
As the laboratory’s business grew, a single integrating sphere system could no longer fully meet their testing requirements. The customer required additional parameters to be measured, such as luminous intensity data, intensity distribution, luminaire efficiency, brightness distribution, glare rating, isolux curves, maximum allowable distance-to-height ratio, and more.
To address these new demands, we recommended the LSG-1800ACCD High Precision Rotation Luminaire Goniospectroradiometer. After confirming the system’s compatibility with their testing space and resolving some technical queries, the customer promptly placed an order for the advanced equipment.
Notably, the laboratory’s experienced engineering team was highly familiar with LISUN equipment. Upon receiving the system, they successfully installed and commissioned it using the installation manuals and instructional videos provided by LISUN. They later shared several photos showcasing the equipment after installation, reflecting their professionalism and satisfaction.
