Buyer Planning Guide

Specify a lightbox by viewing distance, face and installation

A lightbox uses an illuminated face within a frame or cabinet. The main choices are the overall size, face material, cabinet depth, light spacing, single or double-sided construction and mounting method. A shallow box may suit a clean sign graphic, while a deeper cabinet can provide more room for lighting and structure. Buyers should compare the daytime appearance with the illuminated result and confirm how the face and LED components can be serviced.

Graphic and viewing distance

Simple, high-contrast artwork usually remains clearer than fine detail at long distances. Review the design at its finished size and position on the facade or window before approving the face.

Face material

The acrylic face controls diffusion, color and print appearance. Confirm whether the graphic is printed, applied or produced another way and how the required color will appear when illuminated.

Cabinet depth

Depth affects structure, LED spacing and visual projection. The cabinet should be selected with the sign size and required brightness rather than choosing the thinnest option without reviewing the application.

Single or double-sided

A double-sided lightbox can carry the same or different graphics on each face. Projecting signs need a mounting detail that supports the cabinet safely and provides the required clearance.

Outdoor protection

Outdoor models require IP65-rated construction where specified, weather-rated wiring and a suitable driver location. Review rain exposure, fixing details and cable routing for the actual site.

Service and graphic changes

Ask how the face and LED modules can be removed or replaced and where the driver will be located. A replaceable face is useful when campaign artwork or tenant branding may change.

FAQ

Questions buyers ask us.

Can the graphic be changed later?

Yes. We build the frame so the face panel is removable — order a replacement graphic any time without replacing the whole lightbox.

Can each side show different graphics?

Yes. Most clients use the same design on both sides, but a double-sided lightbox can carry different graphics on each face.

Do you handle the wall cut-out?

We supply detailed drawings with exact cut-out dimensions. Your local contractor prepares the opening and the lightbox inserts ready to secure.

Is it weatherproof?

Outdoor models can be specified with IP65 sealing, protected wiring and a suitable driver location. Review rain exposure, mounting and the cable route for the actual site.

How thick does a lightbox sign need to be?

Depth depends on the sign size, face material, LED layout and structure. The correct depth should be selected for the required brightness and installation rather than assumed from another project.

Can a lightbox graphic be replaced later?

Replaceability depends on the frame and face construction. Ask how the face panel is removed, which revision it follows and whether replacement graphics can be ordered separately.

What is required for an outdoor lightbox?

Specify IP65-rated construction where required, weather-rated wiring, a suitable driver position and fixing details for the wall. The site survey should show rain exposure and cable routing.
