valaistuksena

Valaistuksena is the essive-case form of the Finnish noun valaistus, meaning illumination or lighting. In Finnish grammar, the essive case marks a temporary state or role, roughly translating to “as” in English. Therefore, valaistuksena denotes “as illumination” or “in the capacity of illumination.”

The term is used primarily in contexts involving lighting design, architecture, theatre, cinema, and related technical documentation to specify the function or role of lighting in a space or scene. For example, in a design brief one might read that a fixture “ toimii valaistuksena” or that a space is planned “valaistuksena” for a particular mood or effect. The form helps distinguish what something is used for at a given time, rather than its permanent identity.

Related forms and notes: Finnish also has other case forms for expressing roles, such as the translative form valaistukseksi, which conveys a sense of change or transition to being used as illumination. In practice, designers and engineers may refer to both forms when describing lighting solutions, plans, and specifications. The concept fits within broader Finnish grammar that uses the essive to express temporary states and functions.
