What type of lighting is characterized by reflecting only 40-60% of light back to the floor?

Indirect lighting is characterized by reflecting only 40-60% of light back to the floor. This type of lighting uses surfaces, such as walls or ceilings, to bounce light, creating a more diffuse and softer illumination in a space. The purpose of indirect lighting is to reduce glare and distribute light more evenly across an area, enhancing visual comfort.

This type of lighting is often utilized in venues where a gentle ambiance is preferred, such as in sports facilities for spectator areas or lobbies. The focused reflection minimizes the harsh shadows and intense brightness found in direct lighting, which shines light straight down onto surfaces without significant reflection.

In contrast, the other types of lighting have distinct characteristics that do not meet the criteria mentioned in the question. For instance, diffuse lighting scatters light in many directions, while direct lighting focuses illumination directly onto an area, creating bright spots and darker shadows. Ambient lighting provides overall illumination without a defined source and is generally intended to fill a space with uniform light rather than reflect a percentage of light back to the floor.
