The newly released 120mm SEG Lightbox from Expomax represents a significant evolution in modular lightbox display technology. With a 120mm depth, it surpasses the previous 80mm and 100mm versions, enabling larger sizes and significantly improving overall stability.
The robust hardware of this modular lightbox display is engineered for durability and ease of assembly, consisting of:
A frame built from 120mm SEG Aluminum profiles.
High-strength plastic connectors.
Modular light strips, internally supported by Φ20mm aluminum poles.
A key feature of the 120mm seg fabric lightbox is its standardized design. The width is limited to whole meters because the modular light strips are precisely one meter in length, a specification that ensures manufacturing efficiency and consistency.
For brilliant visuals, the graphics are crafted from backlit fabric using dye-sublimation printing. This latest technology delivers rich, vibrant colors and produces durable, wrinkle-resistant results. Each graphic is meticulously printed and hand-sewn to guarantee the highest quality and a perfect fit on the frame.
A Note on Wrinkle-Resistant Claims:
It's important to clarify that no fabric is truly "wrinkle-free." Backlit fabrics are wrinkle-resistant, but folding and packing will inevitably create creases. The term "wrinkle-free" refers to the final displayed effect: when the graphic is stretched taut onto the robust frame of the 120mm SEG Lightbox, the tension smoothly eliminates any wrinkles, resulting in a perfectly smooth and professional appearance for your modular lightbox display.
Premium Hardware Engineering for Larger & Brighter Lightboxes
The EM-18F system is composed of:
120mm SEG Aluminum Profiles – Stronger, thicker, and more rigid to support large-scale builds.
Modular LED Light Strips – Designed in 1-meter lengths for consistent illumination and efficient mass production.
Reinforced Φ20mm Inner Support Poles – Strengthens structural integrity for heights up to 2.5m and widths up to 6m.
Plastic Connectors – Provide fast, tool-free frame assembly for quicker build times and lower labor cost.
Due to the standardized 1m LED strip length, lightbox widths follow whole-meter increments, ensuring perfect component compatibility and streamlined stocking for dealers.

Vibrant, Wrinkle-Resistant Backlit Graphics
The EM-18F uses premium dye-sublimation backlit fabric graphics, produced with state-of-the-art printing technology for:
Rich, vivid color reproduction
Uniform glow across the entire display
High durability and fade resistance
Although no fabric is truly 100 percent wrinkle-free, our backlit SEG graphics are designed to stretch evenly within the frame, minimizing visible wrinkles once tensioned—offering a clean, professional, frameless illuminated presentation every time.

Dealer-Friendly Power System Design
For convenience and easier installation at events, the EM-18F features:
Pre-installed power adaptor mounted directly onto the aluminum frame
Hidden wiring once the graphic is installed
On/off switch located near the adaptor, accessible without removing graphics
This plug-and-play electrical layout significantly reduces setup time while maintaining a clean aesthetic appearance—ideal for rental companies, dealers, and on-site event teams.
Expandable to Larger Sizes & Modular Booth Structures
Thanks to its upgraded depth and reinforced internal structure, EM-18F supports:
Lightboxes up to 6m wide × 2.5m high
Stable performance even in large-format applications
The ability to be combined and reconfigured freely to create:
This makes EM-18F one of the most versatile systems for dealers—one product line that covers multiple booth demands.

Upgraded Packaging – Safer, Lighter, Dealer-Optimized
To help distributors and event companies reduce logistics cost and protect hardware during transport, packaging includes:
This packaging approach offers the best balance of protection, portability, and cost efficiency.
