ljóstilla

Ljóstilla is a term used in Icelandic to denote the act of adjusting or setting lighting in a space to achieve a desired level of brightness and quality of light. It encompasses decisions about the amount, distribution, color temperature, and glare control of artificial lighting, and can involve manual switches as well as automated controls.

The word combines ljós, meaning light, with stilla, meaning to adjust or set. In practice, ljóstilla covers both the selection of luminaires and the configuration of illumination to support function, comfort, and atmosphere in a given environment.

Applications of ljóstilla occur in architecture, interior design, and workplace planning. It aims to balance visual comfort with energy efficiency and may incorporate daylight considerations, glare management, and the use of smart lighting systems. Modern approaches often rely on sensors, programmable controls, and adaptive lighting to maintain appropriate illumination levels throughout the day and across spaces.

History and context: the concept evolved with the spread of electric lighting and the emergence of lighting design as a discipline. In Nordic and Icelandic contexts, ljóstilla is influenced by seasonal daylight variation and sustainability goals, encouraging designs that complement natural light while reducing energy use.
