Wall Washers: Excellence in Vertical Architectural Lighting

Wall washer systems are fundamental tools for defining the breadth and depth of a space. Unlike a standard floodlight, a professional wall washer uses optics designed to distribute luminous flux uniformly over vertical surfaces, eliminating unwanted shadows and creating a smooth transition from ceiling to floor. It is the preferred technical solution for museum displays, luxury retail and corporate facades.

Asymmetric Optic and the Art of Uniformity

The key to a technical wall washer lies in its precision asymmetric lens system. These optics are calculated to deflect the beam of light towards the wall at a specific angle, achieving uniform illuminance even at the highest part of the surface, near the light source. This allows textures to be softened or enhanced according to the installation distance, providing total control over the aesthetics of the building.

Colour fidelity and colour consistency (CRI and MacAdam)

In wall washing, any deviation in the tone of the light is immediately visible. For this reason, our systems incorporate LED modules with a CRI greater than 90 and colour consistency of SDCM < 3 (3-step MacAdam). This ensures that, in a linear installation of several metres, all luminaires emit exactly the same colour temperature, respecting the integrity of architectural finishes and works of art.

Mounting versatility: Recessed luminaires, floodlights and profiles

The wall washer range covers everything from discreet recessed downlights with asymmetric reflectors to track-mounted spotlights and linear systems. This versatility makes it possible to integrate wallwashing techniques both in technical office ceilings and in art galleries, where positioning flexibility is vital to adapt to changes in the exhibition.

Dynamic control and Tunable White

For projects seeking dynamism, wall washers integrate control protocols such as DALI-2 or Casambi. The implementation of Tunable White technology allows the warmth of the light on the wall to be adjusted to follow the circadian rhythm or to drastically change the atmosphere of a hotel or restaurant between day and night, always maintaining the uniformity of the wash.

Frequently Asked Questions (FAQs)

1. What is the difference between Wall Washing and Wall Grazing?

Wall washing seeks uniformity and "cleans" the wall of shadows, installed at a greater distance (approx. 1/3 of the wall height). Wall grazing is installed very close to the surface to highlight rough textures, such as stone or brick, creating deep shadows that accentuate the relief.

2. At what distance from the wall should I install the wall washer?

As a general technical rule, for a uniform wash (Wallwash), the luminaire should be placed at a distance from the wall equivalent to one third of the wall's total height. For example, if the wall measures 3 metres, the wall washer should be placed 1 metre away to achieve the best distribution.

3. Why is glare control important in a wall washer?

Although the light is directed towards the wall, poor optical design can cause direct glare towards the user. High-end wall washers use cut-off reflectors and accessories such as honeycomb louvres (honeycomb) or visors to ensure the light source remains hidden from view from common circulation angles.

4. Can wall washers be used outdoors?

Yes, we offer floodlights and linear wall washers with protection ratings of IP66/IP67 designed specifically for facade washing. These units are manufactured with corrosion-resistant materials and lenses that do not yellow under UV radiation, ensuring that the lighting effect remains unchanged outdoors.
