Why SignLumi

A real factory, not a trading company.

When you buy from a trading company, you pay a middleman and wait on someone else's production line. When you buy from SignLumi, you talk directly to the factory that cuts, welds, assembles and wires your signs.

  • 3,000 m² production floor — we control every step in-house
  • CE & UL certified, with export quality control
  • MeanWell power supplies and Rishang LED modules
  • 2-year warranty on every illuminated sign
