I think it would help our discussion if we distinguish between fill lighting and task lighting.

Fill lighting is used to illuminate a whole room or a general space within a room. Fill lighting is often a more diffuse light, with the light being indirect, or coming from a larger surface, or from multiple light sources.

Task lighting is used in a specific area, generally where a task is to be performed. Task lighting often benefits the task by being somewhat higher in contrast, and having a balanced color spectrum.
