Nature conservation

Artificial light has become an integral part of our daily lives, yet excessive lighting in urban areas can cause significant harm. Bright light sources can disorient insects, birds, and other animals, while also disrupting the natural rhythms of plants and humans.

Studies have shown that in Germany alone, an average of 150 insects die every summer night at a single streetlamp. Birds collide with brightly lit buildings, often injuring themselves or dying as a result. Even trees experience stress due to the absence of darkness, as artificial light can stimulate photosynthesis during the night. In addition, light pollution is believed to interfere with the melatonin levels of both humans and animals, potentially leading to sleep disturbances and hormonal imbalances.

But there is a solution: modern, sustainable lighting concepts. As specialists in street lighting, we develop innovative systems that ensure safety and comfort without harming the environment. By using targeted light distribution, warm colour temperatures, and intelligent control technologies, we reduce the blue light content and thereby minimise the attraction for insects. At the same time, our solutions ensure that light is only used where it is truly needed – without unnecessarily brightening the night sky.

After all, darkness and the starry sky are not just natural phenomena, but part of our cultural heritage. For earlier generations, it was normal to see the Milky Way, planets, or shooting stars in the night sky. Today, much of the urban population has never witnessed these wonders of nature. With our sustainable lighting solutions, we help preserve the beauty of the night – for people and for nature.

• Choosing the right colour temperature: A maximum of 2,700K to 3,000K is recommended; in nature reserves, 1,800K to 2,200K. This ensures lower levels of UV and blue light.
• Correct mounting height: If mounted too low, lighting can create small, extremely bright areas with high contrast to the surroundings. If mounted too high, it can cause glare and unwanted light scatter. The right height helps to distribute light evenly.
• Appropriate lens selection: The right lens directs light precisely where it is needed and reduces upward or lateral spill light. Lenses can also be retrofitted.
• Light intensity and lighting control: Only as much light as necessary should be used. This not only saves money but also protects nature. A lighting control system such as CLEVER LIGHT reduces light pollution by adjusting lighting as needed – for example, by dimming or switching off during low-traffic periods.
