Common Questions About SEG Lightboxes (FAQ)

Thinking about upgrading your trade show or retail display with SEG lightboxes? You’re not alone — and chances are, you have a few of the same questions we hear from customers every day. Here’s a quick FAQ to help you make sense of the details before you buy.

What does “SEG” mean?

SEG stands for Silicone Edge Graphic. It refers to the thin silicone strip sewn around the edge of your fabric graphic. This strip slides into a channel on the frame, creating a tight, seamless finish with no visible borders.

Are SEG lightboxes backlit or front-lit?

SEG displays can be either, but backlit lightboxes are the most popular. They use internal LEDs to evenly illuminate the fabric from behind, giving graphics a vibrant, high-end glow. You can learn more about lighting options in our guide Lighting Tips for Backlit Trade Show Displays.

How do SEG graphics attach to the frame?

The silicone edge on the fabric presses into a small groove in the aluminum frame. Once all sides are inserted, the fabric stretches tight, creating a perfectly smooth, frameless appearance.

Can I replace the graphics later?

Absolutely. One of the biggest advantages of SEG displays is the ability to swap graphics easily. You can reuse the same frame for years — just order new fabric prints when your branding or promotion changes.

How bright are SEG lightboxes?

Modern LED-based SEG lightboxes (like SEGO systems) are extremely bright and evenly lit. They use high-CRI LEDs for accurate color reproduction, ensuring your brand colors stay consistent under show lights.

What’s the difference between single- and double-sided?

Single-sided lightboxes have one illuminated face, while double-sided models shine from both sides — perfect for open spaces or high-traffic aisles. Both use the same frame technology but with different LED placements.

Are SEG lightboxes portable?

Yes — most modern SEG systems are modular and tool-free. They break down into lightweight aluminum sections that pack into rolling cases for easy transport. Read Transport and Storage Tips for SEG Lightboxes for advice on packing safely.

Can they be used outside?

SEG lightboxes are designed for indoor use. Outdoor use can expose electronics and fabric to moisture or UV light that shortens lifespan. For exterior displays, use weather-sealed signage or LED panels built specifically for outdoor environments.

How long do the LEDs last?

High-quality LED systems last up to 50,000 hours or more. That’s years of use before brightness noticeably fades. To extend life, disconnect power when not in use and store frames in a dry environment.

What sizes are available?

SEG lightboxes come in dozens of sizes, from compact counters to full 20-foot back walls. You can even connect multiple frames to build custom layouts. Learn how to plan your setup in How to Configure SEG Mobile Lightbox Sizes.

Do I need a professional to set it up?

Nope — you can assemble most SEG lightboxes yourself in minutes. They use simple push-fit connectors and pre-installed LED wiring. Check out Trade Show Setup Tips for Mobile Lightbox Displays for step-by-step guidance.

Final Thoughts

SEG lightboxes offer professional, high-impact visuals that are easy to set up, ship, and reuse. Whether for trade shows, retail, or office branding, they’re one of the smartest long-term display investments you can make.
