Even illumination is recommended for planar areas, while grazing light is more suitable for textured walls.
In contrast, grazing light is better suited to accentuate spatial textures, such as masonry joints or rough cut stone.
With wallwashing, the angle of incident light gives walls a soft appearance, while grazing light creates striking shadows in the texture and irregularities of the surface.
Grazing light emphasizes the materiality and surface qualities of walls and facades (Fig.
In contrast to the concept of generating homogeneity on the horizontal plane with grazing light from closely spaced luminaires, grazing light from luminaires at greater distances can also be used to create noticeable light patterns along the wall.
The assessment of the light distribution on the wall that results from a luminaire's light control requires a distinction between wallwashing and grazing light.
Since grazing light does not offer uniform brightness in the vertical plane, quality criteria for washlights cannot be directly transferred to grazing light luminaires.
Use uplights, downlights and spotlights to highlight plants and to create moon shadows on the ground, or a grazing light
to emphasise the texture of a wall or fence.
When the curved walls of the circular antechamber slide open, visitors enter a spaceship-type black and white effects gallery where direct ambient light and grazing light
is demonstrated on eight different textured and smooth wall surfaces.
Halogen track lighting utilizing 50-W PAR 30 lamps provides grazing light
on the ceiling-suspended wood-slat scrim curtain, creating a dramatic backdrop for the reception desk.
