The facade lighting design of the building is the lighting that reshapes the night landscape of the building with lights, which is a part of the night scene lighting. The purpose is to use the lighting to highlight the characteristics of the building and organically combine it with the surrounding environment to create a harmonious, beautiful, and distinctive night scene picture, so as to express the night image of the building. Facades have an impact on achieving aesthetic excellence, and this is where façade lighting comes into play. Lighting the façade with lights can turn a building into a real eye-catcher as it accentuates the building and emphasizes key architectural features. Regarding facade lighting design, two concepts (namely, wall washing and wall grazing) need to be carefully considered in the design stage. What is the difference between them? The main difference is how far the light is mounted from the wall, please watch the following part:

Mounting distance from the wall
|Mounting distance||Lighting Ideas|
|Wall Washing||>12"||Spacing distance = ⅓ of the ceiling height|| |
③Indoor plants ④Outdoor signs
|Wall Grazing||<12"||Spacing distance = never more than 12 inches|| |
①Home exterior ②Stone pillars
③Brick wall ④Kitchen backsplash
Wall Washing and Wall Grazing; we've all seen these terms in the lighting industry, but when we're asked about the difference, how many of us are confident in the answers given? Please see below for the detailed differences between them!
2.1 Definition of Wall Grazing
Wall Grazing is another way to illuminate the surface, which is the opposite of wall washing. In terms of the wall-washing effect, the surface lighting is uneven compared to wall washing. By enhancing shadows, wall predation helps to make textured vertical surfaces more visible or prominent. By providing lighting on top of the textured surface, wall scratches will produce very obvious or obvious shadows, making the textured surface of the wall more beautiful.
2.2 Three Installation Rules of Wall Grazing
Installation distance = spacing distance = never more than 12 inches
Avoid unsightly wall texture or badly glued drywall or walls
Stay away from walls where things are installed (unwanted shadows and harsh reflections)
2.3 Wall Grazing Lighting Ideas
If you want to accentuate the walls and add shadows? Here are some ideas for wall grazing lighting. Let's have a look!
Wall grazing is a smart move for a stone house. At night, lights close to the ground can accentuate rough, jagged edges and create a dramatic appearance.
While smoother columns may benefit from wall washing, you may want to accentuate the worn features of older columns. Grazing on the walls adds shade and creates a stately atmosphere.
Interior or exterior, wall grazing can accentuate brick wall details. You can place lights at the top or bottom of the wall, depending on the effect you want to create.
Place accent lights under kitchen cabinets to accentuate the textured backsplash. Wall grazing can draw attention to gaps between tiles or the edge of a sleek, unfinished backsplash.
2.4 How to Wall Grazing
Grazing and wall washing require much the same considerations, wall and ceiling heights, as this will determine:
What light fixture you should use
How far the light fixture is from a wall
The angle of the light fixture
Wall Grazing is ideal for creating a textured aesthetic for materials like brick and stone. Grazing mainly highlights the details of the wall itself so you can choose the right light fixture. Then achieve the effect you want to be based on the distance at which the light fixture is placed.
2.5 Advantages of Wall Grazing
Wall grazing can be performed similar to wall washing, except the lights should be closer to the wall. These lights can even be mounted on the ground, shining toward the ceiling (or sky, if used for outdoor lighting) for an attractive upward lighting effect. This technique is also often used to illuminate carvings or statues. In any case, shadows can be made more or less pronounced by moving the light closer to or away from the wall.
By setting the lighting device closer to the wall so that the lux level decreases as the distance from the lighting device decreases, a wall predation effect can be achieved. The lamp can be placed on the ground and focused in an upward direction to create a mysterious, seductive or fascinating effect on the surface.
This method is usually used for the lighting of statues. By installing lamps near the wall surface or far away from the wall, the shadow effect on the surface can be more or less emphasized.
Unlike wall washes that accentuate wall features, wall grazing turns the wall itself into the focal point of the room. Wall washers illuminate the wall at a wider angle, creating a clear, bright wall and highlighting anything on it, while wall washers sweep across the surface of the wall at a narrow-angle to accentuate roughness or fun through shadows The beauty of the texture. Both techniques draw attention to walls and are a unique way to control how certain spaces or surfaces appear to the human eye.
Choose the appropriate LED wall washer/grazing LED lamps according to the project area and distance: the projection distance is related to the lens and power supply. The higher the optical power, the brighter the projection brightness, and the narrower the lens angle, the longer the projection distance.
It is best to let the manufacturer provide you with the basic luminosity data of their products. Our company SuntechLed has various types of wall washers, and there are very professional designers who provide customers with free Facade lighting design solutions. In addition, the façade lighting is an outdoor lighting design, so the selected luminaires should have an appropriate IP rating and IK rating so that the luminaires can withstand harsh and uneven environments.

Frequently Asked Questions
(1)Wall Grazing vs. Wall Washing: Which is Best?
The main difference between wall washing and grazing is how far the lights are mounted from the wall. Installing a light less than 2 feet from a wall will create a grazing effect, while more than 2.5 feet will widen the angle of the beam and wash the wall. The difference between the two has been specifically written in the article, both techniques allow us to visually see different effects, but which technique is best depends on the material of the wall and the effect you want to create.
(2)How far should wall washers be from the wall?
Mounting distance from the wall >12"
(3)How to install wall washer light?
(4)Where Should Wall Grazing Not Be Used?
Not recommended on walls with lots of hangings or ledges or on artwork and displays - as these create excessive shadows and prolonged darkness, which can be visually disturbing.
(5)When Not to Use Wall Washing？
Wall washes should not be used if the goal is to accentuate features or textures.
