Which aspect is NOT considered a lighting concern?

Price of fixtures is not typically considered a direct lighting concern when discussing the functional and aesthetic aspects of lighting design. Lighting concerns primarily focus on elements that impact the quality, effectiveness, and aesthetics of the light provided in a space.

Color brightness refers to how vivid and intense a color appears under different lighting conditions, which directly impacts the perception of a space and how colors are rendered in that environment. Control systems are crucial for managing how lighting can be adjusted for different times of day, tasks, or moods, therefore they play a significant role in the functionality of lighting in a space. Daylighting control systems are designed to optimize the use of natural light, enhancing energy efficiency and comfort within a building.

While pricing may affect the selection of fixtures, it does not influence how the light interacts with the environment, contributes to the spatial experience, or fits within a designed system of lighting elements. Thus, it stands apart from the core conceptual discussions of lighting design.
