About us

Cumulux Home is a brand of the company OPEN CUMULUX SAS domiciled in Paris.

We are a start-up from two companies Cumulux and OpenCeiling which have joined forces to become the leader in well-being lighting in Europe.

Already present in the professional world for 20 years, we are launching Cumulux Home exclusively dedicated to individuals.

We have developed expertise around improving comfort in the medical and working environment thanks to our photographs of our regions and the integration of technological advances in lighting. We want to use this expertise for the benefit of all those who have problems with natural light in their interior.

Our goal is to always shorten our supply chains to offer the best value for money products possible.
