Daily maintenance of the Fengyi Exhibition Hall’s Star Ring.

Troubleshoot in 4 steps:

1. Power Supply: Confirm the input voltage matches AC 200V~240V/50~60Hz; check if the power cable is securely connected and the switch is on.

2. Cooling Period: Ensure the fixture has cooled for 20 minutes after previous use (mandatory cooling to prevent overheat damage).

3. DMX Signal: If in DMX mode, verify the controller is sending "Shutter On" (CH6: 252-255) and "Dimming" (CH7: 100-255) signals.

4. Internal Wiring: If above checks pass, contact after-sales to inspect internal connections (e.g., lamp holder, driver board) for loose or burned components.

1-2 standard samples are provided free of charge (the customer needs to bear the freight). For customized samples, a cost fee is charged (e.g., 200-500 RMB/unit for appearance-customized samples). If the customer places a subsequent bulk order (meeting the MOQ of the corresponding product), the sample fee can be fully deducted from the payment, and free samples do not need to be returned.

Yes, we can pre-set multiple "lighting scenes" (e.g., welcome mode, performance mode, climax mode, and clearing mode) for you. You can switch between them at will, allowing you to see how the lighting changes dynamically with the music and business hours, creating a truly immersive experience.

The production cycle for regular customization (e.g., appearance logo, parameter fine-tuning) is 15-20 days, and the cycle for complex function customization (e.g., development of a new elevating structure) is 30-45 days. Sample trial production is supported. The sample fee is charged based on the customization cost (the fee can be deducted from the payment after bulk ordering). The trial production cycle is 7-10 days, and bulk production will start only after the customer confirms the sample is qualified.
