After-sales response is slow and fault handling is not timely

A 24-hour after-sales response mechanism has been established: After customers report issues via phone, WeChat, or the official website’s after-sales channels, an after-sales specialist will be assigned within one hour. If on-site repairs are required, a representative will arrive within 24 hours in urban areas and within 48 hours in remote areas. For faulty lamps that cannot be repaired immediately, a “spare lamp advance replacement” service is provided to prevent normal customer use (such as shopping mall lighting and factory production) from being affected by lamp failures.
