The angle of dispersion within which the light flux from its source diverges.
Super spot <10°
Narrow beam angle for strong lighting accents
Spot ≥10°
Concentrated light beam to highlight objects or small areas.
Medium ≥30°
Medium light beam for general lighting if grouped, or spot lighting.
Wide ≥60°
Wide beam angle for general lighting.
Flood ≥120°
Diffused lighting for homogenous illumination of spaces.
Wallwasher
Uniform flood illumination of vertical surfaces.
Looch light 180°
Refracts the luminous flux, creating a light line on the surrounding surfaces.
