India – LISUN engineers successfully installed and trained on the LPCE-3 compact spectroradiometer integrating sphere system

Established in 2006, this customer is a leading supplier and trader of LED lighting products in New Delhi, India, focusing on mainstream lighting products such as LED bulbs, LED tubes and downlights. With years of deep cultivation in the industry, rich experience and consistent product quality, the customer holds an important position in the local market and is a highly competitive lighting product distributor in the region. It has long provided a wide range of high-quality lighting products to the market, building a strong industry reputation and extensive customer resources.

As global lighting markets impose increasingly stringent requirements on product photometric, colorimetric and electrical performance, energy efficiency indicators and compliance, the customer faces dual demands for quality upgrading and market expansion. To further enhance product quality control, meet export certification and testing requirements, and optimize its R&D and production inspection processes, the customer planned to introduce a high-precision, multi-functional integrated LED testing system. After multiple rounds of comparison among domestic and international testing instrument brands in terms of performance, compliance and cost-effectiveness, it finally selected the LPCE-3 CCD Spectroradiometer Integrating Sphere Compact System from LISUN, providing professional and reliable testing support for its full range of lighting products.

Based on the characteristics of its core products including LED bulbs, tubes and downlights, the customer has clear testing requirements in actual production and quality management. It needs to conduct comprehensive and accurate measurements of optical, colorimetric and electrical parameters of luminaires:
• Optical parameters: luminous flux, luminous efficacy, radiant power, etc.
• Colorimetric parameters: correlated color temperature (CCT), chromaticity coordinates, color rendering index (CRI), peak wavelength, color purity, etc.
• Electrical parameters: voltage, current, power, power factor, etc.

Meanwhile, the testing process must comply with international standards such as CIE177, CIE-13.3 and ANSI-C78.377, with test data directly applicable for product export certification and customer inspection. The system must support both batch production sampling inspection and R&D verification of multiple models with high efficiency.

LISUN LPCE-3 system fully matches all these requirements. Integrating a fast-response spectroradiometer, optical fiber, digital electrical parameter measuring instrument and precision regulated power supply, the system completes all required photometric, colorimetric and electrical tests in one run without switching between multiple instruments, greatly improving testing efficiency. It features a wavelength measurement range of 350 nm–950 nm, wavelength accuracy and repeatability of ±0.5 nm, chromaticity coordinate accuracy of ±0.003, and color rendering index measurement error within ±(0.3% rd ± 0.3). All precision indicators meet the customer’s strict quality control requirements. Additionally, the system supports both Chinese and English software operation, adapting to the usage needs of operators in different positions.

Upon receiving the customer’s purchase order, LISUN immediately launched the equipment production process, strictly following product technical standards and customer requirements to efficiently assemble and commission the LPCE-3 system, ensuring equipment quality and delivery schedule. After production completion, LISUN dispatched a professional technical team to the customer’s production base in New Delhi, India, to provide on-site installation, commissioning and operation training. Technicians provided hands-on guidance on system operation, parameter setup, routine calibration and maintenance, and patiently answered all operational inquiries, ensuring the customer’s team could operate the equipment proficiently and standardly to fully utilize its testing capabilities.

Since the LPCE-3 system was put into use, the Indian customer has achieved remarkable improvements in product quality, operational efficiency and market competitiveness. High-precision integrated testing has effectively reduced the factory defect rate, ensuring stable compliance of core indicators including luminous flux, color rendering index and color temperature, and significantly decreasing customer complaints and after-sales issues. The fast and efficient testing process shortens single-sample testing cycles, improves batch sampling efficiency, and eliminates high costs and time consumption of third-party testing.

With internationally compliant test reports, the customer has successfully expanded into overseas markets including the Middle East and Southeast Asia, with a steady increase in order volume. Meanwhile, high-precision test data provides a reliable basis for new product R&D, supporting the launch of more competitive products.
This cooperation not only effectively solves the customer’s practical challenges in product inspection, quality control and export certification, but also fully demonstrates the core advantages of LISUN LPCE-3 system in precision, compatibility and practicality. As a professional supplier of testing equipment for the lighting industry, LISUN provides customized testing solutions based on internationally compliant products and comprehensive services. It also offers mature and reliable technical support for numerous domestic and international lighting manufacturers and trading enterprises to achieve quality upgrading and break through market barriers.
