Expedited shipment is supported for urgent orders: For standard models (e.g., conventional PAR lights, 7-lamp 60W wash lights), if stock is sufficient, SF Express/JD Air Freight can be arranged on the same day (freight is borne by the customer; e.g., the air freight for 10 conventional lights is approximately 200-300 RMB), with next-day delivery. For standard models out of stock, expedited production can be arranged (shipment within 3 days), and an expedited fee (10%-15% of the order amount) will be charged. Specific details to be confirmed with the account manager.

Dedicated line logistics (e.g., Anneng, Best Express) is used by default. Express delivery (e.g., SF Express, JD Express) or full-truck transportation can also be arranged according to customer needs. Delivery time:

▪ East China/South China/Central China: 3-5 days.

▪ North China/Southwest China: 5-7 days.

▪ Northeast China/Northwest China: 7-10 days.

▪ Remote areas (e.g., Xinjiang, Tibet): 10-15 days, with an additional remote area freight charge (calculated by weight, specific details to be confirmed with the logistics department).

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.

For prefecture-level cities and above, an "exclusive wholesale cooperation" policy is implemented: If there is already a cooperative wholesaler in a region (with an annual purchase amount of ≥ 300,000 RMB), no second wholesaler of the same type will be developed. For county-level regions, 2-3 wholesalers can be developed based on market demand, but clear sales scopes must be divided (e.g., by town) to avoid vicious competition.
