Take me directly to Our products

At Carus we offer modern LED lamps for attractive prices. Our top priorities are quality and eco-friendliness at fully automated production. The location in the heart of Germany supports the local economy and brings the semiconductor technology back into the country of its origin. At present we stem an output volume of 10 Mio. lamps per year. Carus` product range puts it´s focus on retrofit lamps that vary in several product specifications, which meet all requirements. Our R&D department constantly refines and develops new solutions and ideas. Carus is a specialist in the field of retrofit LED lamps and develops all of the lamps´ components inhouse.


Guaranteed by the fully automated production line, every single product passes through a 100% output inspection. Only fully working products reach the shipping pallet. Nevertheless, we can minimize the cost by using automatic operations. 


Our lamps save up to 90% electricity at a life span of 25 years. Compared to similar products Carus LED lamps are the most eco-friendly and resource-saving lamps on the market. The abandonment of adhesive imrpoves the recyclability of the

LED lamps. Therefor we have been awarded and funded by the Environmental Innovation Program of the German Federal Ministry for the Environment. The local production saves additional 400 container shipments from the Far East annually which corresponds to an average saving of CO2 of more than half a million tons.

Made in Germany 

Our lamps are produced in our plant in Fronhausen near Marburg. We strengthen the region, develop the technology on site, avoid long delivery routes and save high transport costs and the emission of carbon, which are caused from the usual shipments from Far East. So you can illuminate your livingspace with a green conscience.
