Sustainability and energy efficiency are at the heart of the sera Group’s corporate strategy. With the recent replacement of the lights at its headquarters in Immenhausen, the company is sending a further signal of its commitment
to acting in an ecologically responsible manner while also creating optimal working conditions. Within a few weeks, hundreds of lights in the halls, offices and outdoor areas were replaced by modern LED systems – a measure that not only reduces energy consumption but also improves the working environment.

Light replacement as a milestone in sustainability
Replacing old lighting with energyefficient LED lights marks another significant milestone in the sera Group’s sustainability strategy. The new lights not only significantly reduce energy consumption, but also provide a more pleasant, even light and about 300% better illumination. These improvements help employees to concentrate and contribute to a more productive and healthier working environment. A central aspect of the project was the quick and smooth implementation in order not to interfere with ongoing operations. The cooperation with Grünlicht Beleuchtungskonzepte GmbH proved to be particularly successful in this regard.

Grünlicht: A reliable partner for wellthought-out solutions
The sera Group relies on partners who share its high standards for sustainability and efficiency. Grünlicht Beleuchtungskonzepte GmbH meets these requirements and exceeds them in many respects. The Kassel-based company offers
a comprehensive range of services that goes far beyond the mere supply of lighting systems. From the initial site survey and detailed lighting design to professional installation, Grünlicht has taken on the entire process. The company’s
expertise in proactively integrating legal requirements such as the new Ecodesign Directive into the planning is particularly appreciated. This directive, which came into force in July 2024, places high demands on the efficiency, durability
and resource conservation of products. Grünlicht has optimally implemented the project not only with regard to current, but also future standards. Its proximity to Kassel enabled Grünlicht to react flexibly and quickly to the requirements of the
project. This reliability and the holistic understanding of sustainable lighting solutions make Grünlicht an ideal partner for the sera Group.

Technical innovation: DALI and MacBright
In addition to the collaboration with Grünlicht, the sera Group also relies on innovative technologies and quality products. The hall lighting was equipped with the DALI system, which enables precise control of light intensity. This system supports various scenarios and dimming options, thus ensuring maximum energy savings while maintaining the same quality of light. The light band luminaires used are from the renowned manufacturer MacBright GmbH, which is known for sustainable and highquality lighting solutions. An outstanding feature of MacBright is its in-house lighting laboratory, where products are developed and tested to ensure maximum efficiency and performance. 80% of the luminaires and components are produced in Europe, which guarantees the highest quality and short delivery times. The high quality of workmanship of the luminaires and their adaptability to different requirements were decisive factors in their selection.

Sustainability in the sera Group
The light replacement is part of a comprehensive approach that the sera Group is pursuing to reduce its carbon footprint. In addition to energy-efficient buildings, a modern mobility strategy with electric vehicles and a strong circular
economy, this project shows how targeted measures can create added value for people and the environment. The close cooperation with Grünlicht and the choice of high-quality technologies and partners underline the sera Group’s commitment to combining innovation and responsibility. The replacement of luminaires at the sera Group is more than just a technical upgrade. It is another important step on the road to a sustainable future. With Grünlicht as a competent partner, the consideration of the latest legal requirements and the use of the latest technologies, the sera Group shows how sustainability and efficiency can harmonise. This project is a prime example of the implementation of ecological responsibility in industry.
