About Us

Take me directly to Range of services

Carus GmbH & Co. KG’s headquarter is in Marburg, Germany. This is where Carus develops and manufactures modern LED bulbs in millions of units at the highest quality.

LED bulbs are digital products and save about 85% energy compared to conventional light bulbs.

Carus was founded by Seidel GmbH & Co. KG (since 1830), a technology company, which has been designing aluminum and plastic packaging for cosmetics brands such as Chanel, L‘Oréal, Estée Lauder, Dior, Helena Rubinstein, Hugo Boss and medical technology companies. Managing Director Dr. Andreas Ritzenhoff took advantage of the company‘s technical know-how to develop a new digital pillar in lighting technology.

Dr. Ritzenhoff received the Diesel Medal, Germany‘s oldest innovation prize, for the innovation of an ecological, fully automated production of LED bulbs in Germany and was awarded the Entrepreneur of the Year 2014 by the Harvard Business Club Germany.

Carus is also funded by the Federal Environment Ministry within the framework of the environmental innovation program. The bulbs from Carus were nominated for the German award „ecodesign“ because of its outstanding savings due to its efficient production. In October 2016 the young company succeeded in developing the world‘s first LED bulb, which is allowed to carry the certification „Blauer Engel“, an internationally acknowledged eco-lable.
