TERSEN's purpose is to add value by creating lighting systems that are relevant to both day and night-time designs. We strive to deliver products that are always meaningful in both form and performance. In every way, our desire is to relate to man, environment, and most importantly to architecture in all applications.

The name TERSEN was created by uniquely combining two Latin words: Tersus and Lumen. The literal translation of Tersus is clean, neat, and correct; while Lumen is defined as a unit measure of light. Hence, when combined Tersus + Lumen, TERSEN was born to symbolize a new meaning of clean light.

At TERSEN, we embrace the basic tenet that geometry has a special relationship to all relevant design. We believe that there is a special relationship between man and his environment, the environment and architecture, architecture and light; and we refer to these interrelationships as the founding principles of excellent product design.
