Is street lighting using LED technology really more efficient than conventional lighting with high-pressure sodium lamps?

Are LED streetlights more dazzling than conventional lights?

What effect does a half-night lighting schedule have on the perception
of objects in nighttime traffic?

And what is expected of LED technology in 5 to 10 years?

Answers to these and many other questions can be explored and demonstrated on the LED Walkway in Berlin. Spanning 1,500 meters on the grounds of the German Museum of Technology, the walkway offers visitors the opportunity to experience innovative LED lighting firsthand in a variety of ways.

Five different zones explore topics such as energy efficiency, glare reduction, visibility, adaptive lighting, task lighting, light color, and color rendering. Information is conveyed through informational signs, an e-terminal, and QR codes on the light poles.

The project aims to demonstrate the diverse possibilities of LED technology for the first time under real-world conditions, using various visual targets and glare sources. The focus is on raising awareness of the topics of light and energy. Light quality and energy efficiency become tangible.

Among other things, the exhibition demonstrates how efficiency and light quality depend on pole height, pole spacing, surrounding buildings, light distribution, light color, weather conditions, and sources of glare. Questions regarding potential savings, operational management, investment and ongoing costs, disruptive light pollution, and traffic safety can be answered directly at the exhibit. The target audience includes those with an interest in science and public sector decision-makers, as well as park visitors, tourists in Berlin, and visitors to the Museum of Technology.
