A light box is a panel that illuminates a printed or fabric graphic from behind. The branding lives in the graphic, which can be changed. A light box itself is a neutral frame-and-diffuser product.
An illuminated sign is a fixed piece where the branding or lettering is integrated into the hardware itself. Changing the message means changing the hardware.
When to choose a light box:
- The message, graphic, or branding will change over time
- The same frame needs to serve different campaigns or clients
When to choose an illuminated sign:
- The message is permanent — a company name, a logo, a fixed tagline
- The installation is a brand-defining permanent feature
