Light impact and luminaire arrangements
Light for shelves
Emphasising shelves with wallwashing
Wallwashing achieves the uniform illumination of shelf surfaces. The result is the even distribution of brightness from the top to the bottom of the shelves, so that products gain the same prominence. In contrast to accent lighting, the luminaires need not be realigned if product arrangements change.
Rule of thumb for arranging planar lighting
For uniform vertical lighting, the distance to the wall (a) of lens wallwashers should be around one third of the room height (h). For good linear uniformity the luminaire distance (d) of lens wallwashers can be up to 1.3 times the distance to the wall (a). a = 1/3 x h d ≤ 1.3 x a Tip for luminaire selection: Wallwashers with a predefined alignment to the wall save installation time because realignment is not necessary.
