Zhejiang Lanxi Xinda Lighting Supply CO., LTD. has been in business since 1992, which is longer than most new lighting suppliers and suggests experience in the industry. They offer a mix of traditional lighting products like mercury lamps and high-pressure sodium lamps, which are still used in some industrial and outdoor settings, and more niche items like infrared saunas, indicating a broader product range than typical lighting suppliers. Being based in China gives them access to large manufacturing capabilities and low production costs. However, none of their key verification details — including work email, phone number, or business documents — are confirmed, which raises concerns about legitimacy and reliability. Buyers should verify their identity and request additional proof before placing large orders. This lack of verification is common among older suppliers who may not have updated their digital presence, so it's important to cross-check with other sources or past buyers.
