2. MOQ & Lead Time: Wedding & event distributors usually prefer low MOQ; large brand projects need high stable output.

3. Structure: Check frame material (steel / aluminum), LED brand, power supply, IP rating (IP65 for outdoor).

4. Shipping: Most factories support FOB Shanghai / Shenzhen / Guangzhou / Xiamen; confirm whether they provide palletized export packaging.
