Choosing the right SEG lightbox is not simply a matter of selecting the thickest frame or the lowest price. Frame depth influences how the lightbox is mounted, illuminated, transported, assembled and used.
As a practical starting point:
A 60mm (2.36-inch) profile is best suited to slim wall-mounted installations.
A 65mm (2.56-inch) profile is a cost-effective option for compact freestanding and retail displays.
An 80mm (3.15-inch) profile offers a balance of portability, stability and single- or double-sided display options.
A 120mm (4.72-inch) profile is generally the better choice for large freestanding lightboxes and modular trade show booth systems.
However, frame depth alone does not determine performance. Overall dimensions, LED configuration, extrusion design, connectors, internal supports, feet, graphics and packaging must also be considered.
This guide explains the differences among 60mm, 65mm, 80mm and 120mm SEG lightboxes so buyers, distributors and exhibition companies can choose the right system for each project.
Project Requirement | Recommended Frame Depth |
|---|---|
Slim, permanent wall-mounted display | 60mm / 2.36 inches |
Compact freestanding retail or event display | 65mm / 2.56 inches |
Medium-sized single- or double-sided display | 80mm / 3.15 inches |
Large illuminated trade show backwall | 120mm / 4.72 inches |
Modular 10ft, 20ft or larger booth system | 120mm / 4.72 inches |
Fast-moving, cost-sensitive distributor product | 65mm / 2.56 inches |
Reconfigurable exhibition and rental inventory | 120mm / 4.72 inches |
These recommendations describe common applications within the EXPOMAX product range. The final specification should always be confirmed according to the finished size, lighting system and installation environment.
SEG lightbox frame depth generally refers to the nominal front-to-back depth of the frame profile.
For example, a 120mm SEG lightbox has a profile approximately 4.72 inches deep. This measurement is different from the visible width and height of the finished display.
Frame depth affects several parts of the system:
Space available for LED modules and power components
Distance between the LEDs and the fabric graphic
Light diffusion and brightness uniformity
Structural rigidity
Compatibility with freestanding feet and connectors
Single-sided or double-sided configurations
Packing volume and shipping cost
Suitability for modular booth construction
A deeper frame is not automatically brighter or better. A properly engineered slim lightbox may outperform a poorly designed deep lightbox. LED optics, graphic diffusion, frame construction and finished display size must work together.
Profile Depth | Typical Positioning | Common Installation | Main Advantage | Main Consideration |
|---|---|---|---|---|
60mm / 2.36 in | Slim architectural lightbox | Primarily wall-mounted | Space-efficient and visually clean | Not normally the first choice for large freestanding booths |
65mm / 2.56 in | Compact commercial lightbox | Freestanding or wall-mounted | Lower material and shipping requirements | Better suited to small and medium formats |
80mm / 3.15 in | Mid-depth professional display | Freestanding, wall-mounted or suspended | Good balance of stability and portability | Less modular capacity than deeper booth systems |
120mm / 4.72 in | Large modular display system | Freestanding and booth-integrated | Greater structural and configuration flexibility | Larger profile requires careful packing and system selection |
A 60mm SEG lightbox has a profile depth of approximately 2.36 inches. It is a strong choice when the lightbox needs to sit close to a wall and become part of the surrounding interior.
Within the EXPOMAX range, the EM-18GA is designed as a single-sided wall-mounted SEG lightbox. Its slim aluminum structure is suitable for:
Retail feature walls
Corporate reception areas
Galleries and museums
Shopping malls
Airports and transportation hubs
Showrooms
Hospitality interiors
Permanent branded wall installations
The smaller profile helps create a clean, architectural appearance without extending too far into the room. It also provides sufficient internal space for an integrated lighting and power system designed for single-sided illumination.
Choose a 60mm system when:
The display will be installed directly on a wall.
Only one illuminated graphic is required.
Floor space is limited.
The project requires a slim and permanent appearance.
Custom wall dimensions are more important than modular booth expansion.
For large freestanding displays, open booth layouts or structures viewed from two sides, a 65mm, 80mm or 120mm system may be more appropriate.
A 65mm SEG lightbox is approximately 2.56 inches deep. Although the difference between 60mm and 65mm is only about 0.20 inches, their intended configurations can be different.
EXPOMAX positions its 65mm aluminum SEG lightbox as a compact, cost-effective system for small and medium commercial displays. It can support freestanding or wall-mounted installation and single- or double-sided graphics, depending on the selected configuration.
Typical applications include:
Retail promotions
Small trade show displays
Event signage
Franchise campaigns
Seasonal promotions
Brand activation areas
Dealer inventory programs
The slim aluminum profile helps reduce material use, packed volume and shipping weight. This makes the 65mm lightbox particularly useful for distributors that need an accessible entry-level illuminated display with fast turnover.
Choose a 65mm system when:
The finished display is small or medium in size.
Portability and compact packaging are important.
The buyer needs a competitive product cost.
The display may be used either freestanding or wall-mounted.
Graphics will be changed frequently.
A distributor needs a standardized, easy-to-sell lightbox.
The 65mm frame can provide sufficient stability for its intended formats, but larger walls and modular booth structures may benefit from a deeper system.
An 80mm SEG lightbox has a profile depth of approximately 3.15 inches. It sits between compact display profiles and deeper modular booth systems.
The EXPOMAX EM-18C uses an aluminum frame and LED edge lighting. It can be configured as a freestanding, wall-mounted, single-sided or double-sided display, depending on the project.
The 80mm system is suitable for:
Medium-sized trade show displays
Freestanding retail lightboxes
Double-sided promotional displays
Exhibition backwalls
Showroom displays
Illuminated signs viewed from multiple directions
Its deeper profile provides more structural capacity than a slim 60mm or 65mm system while remaining easier to handle than many large-format 120mm structures.
Choose an 80mm system when:
A medium-sized freestanding display is required.
The graphic may need to be visible from two sides.
The project needs more rigidity than a compact profile provides.
Portability is still a major requirement.
The display will be reused across retail, event and exhibition environments.
For buyers who need a professional freestanding display but do not require a full modular booth system, the 80mm profile provides a useful middle option.
A 120mm SEG lightbox is approximately 4.72 inches deep. This deeper structure is designed to provide the space, rigidity and internal support required for larger freestanding displays and modular exhibition systems.
It is commonly selected for:
10ft trade show backwalls
20ft trade show displays
Large illuminated booth structures
Modular SEG booth systems
Reconfigurable rental displays
Retail feature walls
Exhibition entrances
Large brand activation environments
The deeper profile can accommodate internal lighting, supports and modular connections more effectively. However, the exact capability still depends on the extrusion, connectors, feet, lighting layout and overall display size.
The EXPOMAX 120mm range contains several different systems. They should not be treated as the same product simply because they share the same frame depth.
The classic EM-18F uses a 120mm aluminum frame, modular lighting components and internal supporting structures. It is designed for larger display sizes where additional stability is required.
The SEGQuick Pro R1 is a 120mm aluminum modular system designed for fast, tool-free assembly and large seamless graphics. Standard booth applications include approximately 8ft, 10ft and 20ft-wide display walls.
The R2 PVC version combines a 120mm profile with a non-conductive PVC structure. Its modular sections help distributors reduce the number of finished sizes they need to stock while providing a cost-conscious option for exhibition and retail projects.
The R2 aluminum version uses a powder-coated, PVC-free aluminum structure. It combines modular expansion with improved rigidity, recyclable material and compact packaging for professional distributors and long-term display programs.
The correct 120mm model therefore depends on material preference, required configuration, budget, transport method, inventory strategy and sustainability requirements.
Frame depth creates the space in which light travels and diffuses before reaching the printed fabric. However, the relationship between depth and brightness is not as simple as “deeper means brighter.”
Two common lighting configurations are used in fabric lightboxes.
In an edge-lit system, LED strips are installed around the inner perimeter of the frame and direct light toward the center.
Edge lighting can support a slimmer profile and is commonly used for:
Wall-mounted displays
Compact freestanding lightboxes
Medium-sized illuminated signs
Applications where reduced frame depth is important
As the illuminated surface becomes larger, LED optics, profile depth and fabric diffusion must be carefully matched to prevent a darker center or uneven brightness.
A direct-backlit system positions LED modules behind the fabric graphic. This arrangement generally needs more distance between the LEDs and fabric so individual light points can blend into a uniform image.
It is commonly used for:
Large exhibition backwalls
Modular trade show displays
High-impact retail graphics
Large illuminated surfaces
When comparing suppliers, buyers should evaluate more than the frame depth. They should also ask about:
LED placement
Light diffusion
Color temperature
Power supply position
Heat management
Backlit fabric specification
Brightness consistency at the finished size
Replacement availability for LED components
For an important project, request illuminated images or video from a comparable finished size rather than evaluating only an unlit frame sample.
A deeper extrusion can provide greater structural capacity, but depth is only one part of stability.
The final performance also depends on:
Aluminum or PVC profile design
Extrusion wall thickness
Corner connectors
Internal support bars
Section joints
Base feet
Finished width and height
Added accessories
Number of connected modules
Frequency of assembly and disassembly
A properly designed 65mm or 80mm lightbox can be stable for its intended display size. A larger booth wall, however, may require a 120mm structure with additional internal supports and connection points.
Always specify the complete display dimensions and application before selecting a profile.
A thinner frame often uses less material and may reduce packed volume. However, shipping cost cannot be calculated from frame depth alone.
A deeper modular system may be divided into shorter sections and packed efficiently, while a thinner custom frame may contain long components that increase freight costs.
Distributors should compare:
Gross weight
Package dimensions
Volumetric weight
Number of packages
Carry bag, EPP case or flight case
Protection for LEDs and connectors
Replacement-part availability
Assembly labor
Storage requirements
Number of sizes that must be stocked
The best-value system is not necessarily the one with the lowest hardware price. Total cost should include freight, storage, installation, replacement graphics, maintenance and reuse across multiple projects.
Choose a slim, single-sided wall-mounted system such as a 60mm profile. Confirm the wall condition, electrical access, finished dimensions and maintenance requirements.
A 65mm profile provides a useful combination of visual quality, portability and cost efficiency. It is suitable for frequent graphic changes and standardized retail campaigns.
An 80mm profile offers additional structural capacity while remaining portable. It is suitable for displays viewed from multiple directions.
A 120mm system is generally the stronger choice for large illuminated walls because it provides greater space for lighting, support structures and modular connections.
Choose a system designed specifically for repeat assembly and reconfiguration. A modular 120mm lightbox can help rental companies and distributors create different booth widths from a shared component inventory.
Before requesting a quotation, provide the manufacturer with the following information:
Finished display width and height
Wall-mounted, freestanding, suspended or booth-integrated installation
Single-sided or double-sided viewing
Indoor environment and expected operating time
Required lighting configuration
Frequency of assembly and graphic replacement
Quantity and destination market
Preferred frame material
Required carry bag, protective case or flight case
Electrical and certification requirements
Required shelves, counters, monitors or booth connectors
Expected future expansion or modular reuse
Providing complete project information allows the manufacturer to recommend the correct profile, lighting system, support structure and packaging.
Distributors do not necessarily need to stock every possible finished size.
A practical product range can include:
60mm wall-mounted lightboxes for permanent retail and interior projects
65mm compact lightboxes for fast-moving and price-sensitive orders
80mm systems for medium freestanding and double-sided applications
120mm modular systems for large exhibitions and configurable booth projects
Compact standard sizes can be stocked for quick delivery, while larger custom and modular projects can be produced according to confirmed orders.
This structure allows a distributor to serve several market levels without treating every SEG lightbox as the same product.
There is no single best depth for every project. A 60mm frame is suitable for slim wall-mounted displays, 65mm for compact commercial displays, 80mm for medium freestanding applications and 120mm for large modular booth systems.
A 65mm lightbox prioritizes compact packaging, lower material requirements and small-to-medium display applications. An 80mm lightbox provides additional frame depth for medium-sized freestanding and double-sided displays.
Choose 80mm for a portable, medium-sized freestanding display. Choose 120mm when the project requires a large illuminated backwall, multiple connected panels or a modular booth structure.
No. Brightness depends on LED output, LED placement, display dimensions, fabric diffusion and power configuration. Frame depth supports the lighting design but does not determine brightness by itself.
Some 60mm profiles may support freestanding applications, but the EXPOMAX EM-18GA is specifically positioned as a wall-mounted system. Always confirm the intended configuration of the exact model.
Aluminum offers rigidity, durability and recyclability. PVC provides electrical non-conductivity and can support cost-conscious product programs. The better choice depends on the market, application, transport requirements and distributor positioning.
Not always. Frame channels, finished graphic dimensions, silicone strip thickness and sewing tolerances can vary. Use the template supplied for the exact frame before producing replacement graphics.
Provide the finished size, installation method, viewing sides, frame material, quantity, destination, accessories, packing requirements and expected application. These details help prevent incorrect profile or lighting recommendations.
The correct SEG lightbox should match the project rather than forcing the project to fit a single standard frame.
EXPOMAX supplies 60mm, 65mm, 80mm and 120mm SEG lightbox systems for wall-mounted displays, freestanding promotions, retail environments and modular trade show booths.
For distributors, wholesalers and exhibition companies, EXPOMAX also supports custom dimensions, OEM and ODM programs, replacement graphics, modular configurations and international shipping solutions.
