Valaistavat

Valaistavat is a Finnish term derived from the verb valaistaa, meaning to illuminate or light up. In practical use it functions as a participial phrase that attributes the sense of “to be illuminated” to a plural noun. The expression is common in planning, architecture, interior design, stage lighting, and event production to designate elements that are intended to receive lighting.

In everyday use, valaistavat appears in phrases such as valaistavat tilat (areas to be lit) and valaistavat kohteet (objects to be illuminated). It is typically employed in planning documents, lighting design briefs, and procurement specifications to specify requirements for illumination. The form signals that the highlighted items are part of a lighting plan rather than already lit.

Relation to related terms: valaistavat is built from the root valaista with participial suffixes that create adjectival or noun phrases describing things related to illumination. The corresponding singular form would be valaistettava, meaning “to be illuminated,” and related terms such as valaistus refer to the lighting itself. Finnish planners often use these participial forms to clearly delineate which parts of a project require lighting considerations and, conversely, which parts are already lit or exempt from illumination work.
