AI-Powered supplier vetting

SummaryJiangmen Gepsen Lighting Electric Co., Ltd. is a China-based limited company established in 2014, with 63 employees and a manufacturing site of 4,393 m². It supplies multiple LED and energy-saving lighting products, operates more than 10 production lines, and reports substantial annual output, including over 4.5 million LED bulbs and over 1.3 million energy-saving lamps. The supplier has strong export exposure, with 90% of sales reportedly from exports, and states that its products reach 20 countries and regions. However, no management-system certifications are currently reported; the company says it is applying for UL certification. Evidence of after-sales systems, customization capability, and independently verified customer references is limited. The supplier’s stated capital and production-output ranges are noted but not used as financial conclusions.

Supplier typeThe supplier is identified as a trade company in one record and as a limited company engaged in lighting manufacturing and commercial trade in others. Its products, production lines, manufacturing area, and output indicate that it functions as a lighting producer with trading activity rather than solely as an intermediary.

CertificationsThe supplier reports no management-system certification ("NIL"). It states that it is currently applying for UL certification, which does not establish that UL certification has already been obtained.

R&D capabilityThe supplier reports four years of total R&D-engineer experience, states that it uses advanced equipment, and says it continues to develop new products. These statements support some product-development activity, but the evidence does not quantify R&D resources, patented technology, or completed innovations.

Production capacityThe supplier reports more than 10 production lines, a 4,393 m² manufacturing plant, and annual output including 4,527,017 LED bulbs, 1,315,615 energy-saving lamps, 50,000 chandeliers, and 50,000 outdoor lamps. This is explicit evidence of established production capacity across several lighting categories.

Client casesThe supplier states that its products are sold to 20 countries and regions, and trade records show transactions associated with MSK KIYINGI INVESTMENTS LTD in Uganda for China 3W bulbs. These records provide some market and transaction evidence, but they do not provide detailed project references, performance outcomes, or independently verified customer testimonials.
