Cut-off street lights control the direction of light. The light in the horizontal direction is limited, so there won’t be any glare or light pollution. Aussi, because most of the light can be cast on the roads, cut-off street lights can increase the brightness and illumination uniformity and save energy. In some cities, street lights on the main roads must be cut off to ensure the safety of drivers.
