Sourcing Tips

• Verify whether the factory owns its independent vacuum forming equipment. Some trading companies outsource thermoforming work and only perform LED assembly, which may lead to unstable quality and longer lead time.

  

• Request material certificates, CE/RoHS test reports and physical samples before placing bulk orders.

• Confirm mold cost, production lead time, MOQ and LED module warranty in the formal quotation.
