What describes lighting that reflects 90% of light onto the floor?

The description of lighting that reflects 90% of light onto the floor is best captured by direct lighting. This type of lighting focuses illumination directly onto a specific area, such as the floor, improving visibility and enhancing the usability of that space. Direct lighting typically uses light fixtures that produce intense beams of light aimed at a designated surface, ensuring a bright and well-lit environment.

This effectiveness is especially important in sports facilities where visibility can impact gameplay, safety, and the overall experience for athletes and spectators. Direct lighting achieves its purpose by concentrating the light output in a certain direction, resulting in high levels of brightness incident upon the surface.

In contrast, diffuse lighting spreads out light more evenly throughout a space but doesn't necessarily reflect a significant percentage directly onto the floor. Indirect lighting, on the other hand, illuminates a space indirectly via reflections off surfaces rather than shining directly onto them. Ambient lighting serves to create a soft, overall illumination without the focus required for specific tasks or areas.
