SummaryYangzhou Lecuso New Energy Co., Ltd. is a China-based limited company in Jiangsu, identified as both a trading company and manufacturer/factory. It operates in lights and lighting and reports three production lines, ten experienced export-trade staff, and presence in one main export market. The supplier demonstrates documented procedures and records for corrective and preventive actions, complaint handling, supplier-service assessment, and quality assurance. It offers broad customization, including design-based and full customization, and reports new-product activity within the past year, but does not provide ODM services or an SDK. Production lead time is stated as within 15 working days in both peak and off-seasons. The supplier has participated in a named 2025 offline trade show, but no specific customer cases are provided. No overseas warehouse, showroom, agent, or branch is reported. Financial records are referenced for 2022–2024, but their contents are not provided.

Supplier typeThe supplier is identified as a limited company, trading company, and manufacturer/factory based in Jiangsu, China. Its stated business scope includes new-energy technology research and development, sales of new-energy equipment, lighting fixtures, and solar-related equipment, which is consistent with its lights-and-lighting commercial focus.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaints, and its service assessment process also has written procedures and records. However, it reports no overseas warehouse, showroom, agent, or branch; service is linked to Shanghai Port, and the stated lead time is within 15 working days in both peak and off-seasons.

R&D capabilityThe supplier reports new-product activity during the past year and includes emerging-energy technology research and development in its business scope. It does not provide an SDK and does not offer ODM services, so the evidence supports product-development activity but not broader platform or ODM capability.

Production capacityThe supplier is identified as a manufacturer/factory with three production lines and states average lead times within 15 working days in both peak and off-seasons. It also has quality assurance and documented supplier-service assessment procedures, but it does not continuously reconcile quantities for every batch or mass-production run.
