Semi-scatter angle

The half-angle describes the area of a light cone within which the light intensity drops to half of its maximum brightness. It is a key aspect in characterizing directional light sources, such as spotlights or floodlights, which concentrate light in a specific direction. The half-angle thus defines the extent of the brightest and most highly focused area of light, while the rest of the light cone exhibits decreasing intensity.

A narrow beam angle produces a narrow, precise beam of light that is ideal for highlighting small areas or objects such as works of art or architectural details. A wider beam angle, on the other hand, produces a broader beam of light that is better suited for evenly illuminating larger areas.

The half-angle is particularly relevant when planning lighting designs, as it affects both the visual impression and the efficiency of the lighting. Modern luminaires often allow the half-angle to be adjusted, enabling both flexible and precise lighting solutions.
