SEG (Silicone Edge Graphics) light box refers to a backlit display system where printed polyester fabric with a sewn silicone edge is slotted into an aluminum extrusion frame, paired with LED light sources. It is widely adopted in trade show booths, retail chain stores, brand showrooms, and indoor backlit signage for its smooth, glare-free illumination and easy graphic replacement.

⚠️ Sourcing Notes

• Many suppliers are full display booth factories rather than dedicated pure light box manufacturers. Confirm whether they have in-house aluminum extrusion capability or only assemble outsourced profiles — this directly impacts lead time and unit cost.

• Request a sample to verify light uniformity before placing bulk orders.

• Double-check that the voltage of the power adapter matches the standard of the destination country.
