Guzhen LED Tube Manufacturers: Complete Buyer Guide to China's Lighting Capital

Why Guzhen is China's LED Tube Sourcing Hub

Guzhen Town (古镇镇) in Zhongshan City, Guangdong Province, is the world's most concentrated LED lighting manufacturing cluster. With over 6,000 factories and suppliers within a 47 km² area, it accounts for roughly 70% of China's decorative lighting exports and a significant share of commercial LED tube production.

For B2B buyers sourcing T8 and T5 LED tubes, Guzhen offers three key advantages: (1) complete supply chain integration from LED chips to finished fixtures, (2) lower production costs than Shenzhen or Shanghai, and (3) a high concentration of factories with DLC QPL, UL, CE, and RoHS certifications serving the North American and European markets.
