After-Sales Support
Can accessories (e.g., power cords, DMX signal cables, lamp beads) be purchased separately after the lights have been used for many years?
Separate purchase of accessories is supported. Common accessories (power cords, signal cables, standard lamp beads) are in stock and will be shipped within 1-3 days after ordering. Special accessories (e.g., hydraulic pumps for elevating lights, XY-axis motors for moving head lights) need to be reserved 3-5 days in advance. The after-sales team can provide accessory installation guidance (e.g., sending installation videos).
Can technical training be provided? For example, teaching customers how to debug DMX consoles and set light addresses.
Free technical training is supported:
▪ Online training: Operation video tutorials and live teaching (e.g., a "DMX Light Control Practical Course" once a month) are provided.
▪ Offline training: For wholesale customers (with a single purchase of ≥ 100 units), technicians can be arranged for on-site training (1-2 days, including console debugging, address setting, and fault troubleshooting).
▪ Customized training: For large-scale projects (e.g., stadium lighting projects), on-site technical guidance can be provided (charged based on the project cycle, specific details to be negotiated).
Wholesale Cooperation
What is the restocking cycle for wholesale customers? Can production be prioritized?
The restocking cycle for standard models is 3-7 days (same-day shipment if stock is sufficient), and the restocking cycle for customized models is the same as the initial customization cycle (15-45 days). For annual cooperative customers (with an annual purchase amount of ≥ 500,000 RMB), a "priority restocking agreement" can be signed, and 10%-15% of safety stock will be reserved to ensure emergency restocking needs are met within 3 days.
Products
The fixture does not respond to the DMX controller. How to fix it?
Resolve with these checks:
1. DMX Address & Channels: Ensure the fixture’s starting address is correct (e.g., 34CH fixture 1: A001, fixture 2: A035) and the controller’s channel count ≥ total fixture channels.
2. Signal Wiring: Use shielded twisted-pair DMX cables (≤150m); install a 120Ω terminal resistor between pins 2-3 of the last fixture’s XLR connector.
3. Signal Amplification: For cable lengths >150m, add a DMX signal amplifier to avoid signal loss; separate DMX cables from high-voltage power cables (≥1m apart) to prevent interference.
