Wall Washer Lights: Illuminating Architecture
Wall washer lights are specialized lighting fixtures designed to evenly illuminate vertical surfaces. They emit a wide beam of light to wash an entire wall with bright, uniform lighting. Wall washers highlight the texture of brick and stone and emphasise architectural details. They are frequently used in both residential and commercial buildings to accentuate foyers, staircases, exterior façades and other architectural features.
Defining Features
Several key features define wall washer lights. They have a wide beam angle, typically between 30 to 40 degrees, that emits a broad spread of light over a large area. They also have shielding around the sides and back of the light to direct illumination towards the wall. Wall washers are often installed at the top of walls, aiming down, to create even illumination from top to bottom.
Wall washer lights also provide relatively high light intensity, ranging from 5,000 to over 20,000 lumens. The higher light levels ensure sufficient brightness to highlight large walls. Dimming controls are commonly used with wall washers, enabling adjustment of light levels for different effects. The colour temperature of the light also varies depending on the desired ambiance, ranging from warm white (2700K) to cool daylight (6500K).
Applications
The most common application of wall washers is highlighting exterior architecture. They are used to illuminate building façades, illuminating their shape, texture and details. Religious buildings, memorials and notable landmarks frequently use wall washers to draw attention and accentuate their structure at night.
Wall washers are also popular for illuminating interior entryways, lobbies and atriums. A wall of light greeting visitors can create a memorable first impression. Staircases are also often washed with light to guide people up and down, as well as to showcase any intricate detail.
Some designers use wall washers to spotlight textured interior walls like brick, stone or wood. Bathing these surfaces in light enhances their natural beauty and texture. This approach works well in rustic or industrial-themed spaces. Wall washers can also be used in art galleries and museums to illuminate prized works of art or artifacts on display.
Current and Future Trends
Energy efficient LED technology has enabled brighter wall washer fixtures that consume less energy. LEDs also allow for warmer dimming to lower light levels. These LED wall washers are replacing older fixtures with halogen and incandescent bulbs.
Automated lighting controls are also being integrated into wall washer systems. Sensors can adjust the light intensity based on ambient light levels or the time of day. This automation enhances the energy efficiency, convenience and versatility of wall washers.
Precision optics and LED chips are also advancing to produce higher quality light in narrower beam angles. Narrow spot wall washers, between 20 to 30 degrees, provide tighter control of the spread of light. This enables more targeted wall washing and new creative possibilities.
In the future, digital lighting and smart phone apps may enable programmed and interactive wall washer displays. The color, intensity and timing of the lights could automatically change to highlight different architectural details or to create visually stunning light shows. Innovations in wall washer technology and market trends continue to make these versatile lighting fixtures more multi-purpose, dynamic and engaging. Overall wall washers remain an elegant way to turn bare walls into dramatic canvases of light.
