We provided an LED lighting driver solution for a large commercial complex in Guangzhou. The client's original power supply system lacked scalability and frequently experienced single-point failures, impacting the overall lighting performance. We recommended an LED driver with multi-unit parallel connectivity, enabling flexible expansion and improving system stability by 300%. The solution also includes backup redundancy, ensuring continuous and stable operation even at full load. The client reported no system outages and significantly reduced maintenance costs. The partnership has continued for over five years.
