Even after many years repairable 

Sustainability, creativity and customization. 

Sustainability is for us as a manufacturer of professional lighting solutions, LED aquarium lighting in zoos and LED lighting for plant cultivation not a buzzword, but lived practice. 

Our LED lights, manufactured in Germany, are made of robust, and also seawater-resistant aluminum and thus do not end up one day on a steadily growing mountain of plastic waste.

 All Giesemann lights can be easily repaired for many years and do not need to be
replaced.  If no product from our portfolio is suitable for your applications, we have the possibility to manufacture a lighting solution individually according to your needs in our production and development facility in Nettetal.
