Indoor and outdoor lightbox comparison
In the world of advertising and signage, light box displays have become a popular choice for businesses looking to attract attention and promote their brand. Whether it’s for displaying menus, promotions, or company logos, light boxes offer a visually appealing and attention-grabbing solution.

Outdoor Light Box: How does an outdoor lightbox signage work?

An outdoor light box is specifically designed to withstand the elements and provide visibility in various weather conditions. These light boxes are typically larger and more robust compared to their indoor counterparts. They are constructed using weather-resistant materials, such as aluminium or stainless steel, and feature a strong and durable frame. One of the main differences in this kind of signage is the presence of weatherproofing. Outdoor light boxes are sealed tightly to protect the internal components from rain, snow, dust, and other outdoor elements. They often come with a weatherproof gasket and have a high IP (Ingress Protection) rating, ensuring that the sign is resistant to water and dust penetration. The illumination in outdoor lightboxes is typically provided by fluorescent tubes, LED lights, or a combination of both. These lights are carefully positioned within the box to evenly distribute illumination and maximize visibility. The use of LED lights is more common nowadays due to their energy efficiency, longevity, and brightness. outdoor lightbox sign
