Hangzhou Sinogreen Optoelectronics Co., Ltd

Hangzhou Sinogreen Optoelectronics Co., Ltd. is typical of many Chinese optoelectronics suppliers offering LED light bars and tubes at competitive prices. Founded in 2010, the company has been in the market for over a decade, which suggests experience in manufacturing and meeting standard customer demands. However, no phone, work email, or business documents have been verified — this raises concerns about legitimacy and responsiveness. Buyers should verify the company's identity independently before placing large orders. While based in China, a country with strong manufacturing capacity, the lack of verification makes it harder to trust the supplier's reliability. For buyers, this means extra due diligence is needed to confirm the company's real operations and product quality.
