Outdoor advertising with illuminated letters is one of the most effective forms of brand presentation. It ensures visibility, strengthens your image and attracts attention from afar, even in the dark. At the same time, purchasing this type of advertising comes with a few typical pitfalls. In this article, we highlight the five biggest mistakes that many companies make and how Light and Sign reliably solves these challenges.
1. Not paying attention to energy efficiency
Modern LED illuminated letters save energy, reduce maintenance costs and ensure long-lasting results. Nevertheless, many suppliers still rely on outdated technology that consumes an unnecessary amount of electricity.
At Light and Sign, we work exclusively with high-quality LED modules that enable maximum efficiency and uniform illumination. An example of this can also be found in our projects relating to sustainable lighting solutions.
2. Choosing the wrong materials
Cheap materials can quickly fade, rust or become brittle. Especially outdoors, UV light, rain and temperature fluctuations have a significant impact on service life.
Our illuminated letters are made of robust acrylic, high-quality aluminium and UV-stable front materials. We also offer professional finishing and foiling services, which provide an additional protective layer and enhance the appearance.
3. No professional lighting design
Standard letters are often purchased without a lighting concept, which leads to shadows, uneven illumination or poor visibility from a distance.
Light and Sign creates each project individually and ensures that visibility, light intensity and colour effect are perfectly matched to your brand. We show more inspiration in our articles on LED innovations.
4. Underestimating safety and installation
Incorrect mounting, poor cable routing or a lack of safety checks can be costly or even pose a risk.
Our team takes care of the entire professional installation, including substructure, electrical safety measures and final functional testing. For many companies, this makes a decisive difference in their daily operations and public image.
5. Not taking brand impact into account
Illuminated letters only achieve their full effect when they perfectly match the brand. Consistent colours, appropriate typography and coordinated light intensity are crucial for a strong appearance.
At Light and Sign, we develop every solution to be tailor-made, so that the shape, colour, material and lighting effect match your identity and your outdoor advertising becomes a real eye-catcher.
