Everything about outdoor wall washer lights you need to know

What is outdoor led wall washer light?

LED wall washer lights are a type of outdoor landscape lighting. As the name implies, these lights create a washing effect on the wall, resembling water, and are commonly used to illuminate and highlight architectural features or walls in outdoor spaces.It is known for its ability to create a broad and even beam of light. Typically used for decorative or accent lighting. Some refer to them as outdoor LED strip lights due to their long, strip-like shape.

The technical specifications of LED wall washers share similarities with LED floodlights. However, LED wall washers stand out due to their linear shape, providing better heat dissipation capabilities.

Basic Parameter

The widely used LED wall washers basically use 1W high output LED guardrail tube (each LED tube will have a high-efficiency lens made of PMMA, and its main function is to redistribute the light emitted by the LED guardrail tube), showing Single-line arrangement (two-line or multi-line arrangement, classify it as LED floodlight), most of the LED guardrail tube of LED wall washers share a radiator, and their light-emitting angles are generally narrow (about 20 degrees), medium ( About 50 degrees), wide (about 120 degrees), the farthest effective projection distance of high-power LED wall washer (narrow-angle) is 5-20 meters, and its common power is about 9W, 12W, 18W, 24W, 36W and other power forms, and their common dimensions are generally 300, 500, 600, 900, 1000, 1200, 1500mm, etc., different lengths and power densities can be selected according to actual engineering applications.

Detail Parameter

Projection distance: 5~20 meters according to the lens, the smaller the angle, the farther the projection distance.

Lighting angle: 6-90 degrees floodlight

Mirror surface: glass reflective lens, the light transmittance is 98-98%, not easy to fog, and can resist UV radiation

The lamp body is made of pure aluminum, and there are many optional shapes, such as square and long linear wall washer light, and the optional length can be arbitrary: 300, 500, 600, 1000, 1200, or 1500mm. Width and height are fixed (of which 1 meter is a regular product)

IP Protection level: IP65-IP67 (IP68 is the highest) the effect of a structural waterproof wall washer can reach I67, with high waterproof and long-term characteristics. Even if it is used for a long time, its waterproof performance will not be affected.

LED wall washers come in various shapes, such as long, round, and square, allowing for flexibility in installation on different building structures. The control methods have evolved from master-slave connection to support offline or built-in control, with options for wireless DMX control. The channels for light effects have expanded from 3 to 4 to 20 channels, enabling customizable luminous effects for diverse color shaping and creating unique visual impacts on large buildings

Power supply : It can be divided into DC and AC. Generally, the built-in power supply is externally connected to AC220V (Japan AC110V) mains, etc., and the external one is generally low-voltage DC24V, DC12V, DC36V, and so on. The voltage is also different according to different requirements.

Color: full-color color, colorful color, red, yellow, green, blue, purple, white, and other colors.

Development trend: Wall washers are mainly developed towards ultra-thin, because the transportation cost of ultra-thin outdoor wall washer light will be relatively lower, and it is more convenient for high-altitude operations.

Control Way

Outdoor wall wash lighting is controlled by the built-in microchip. In smaller-scale projects, it can operate without the need for a separate controller.Dynamic effects like gradual transitions, sudden shifts, color pulsations, random variations, and gradual shifts can be created. Alternatively, it can be controlled through DMX to achieve effects like chasing and scanning.

High-power LED wall washers offer two control options: external and internal. Internal control eliminates the need for an external controller and can incorporate multiple built-in modes (up to six) for color changes. In contrast, external control necessitates an external controller to facilitate color changes. Most applications in the market opt for external control.

Installation guide

Generally, there are differences for different types led linear wall wash lighting, for the high voltage input type (110VAC or 220VAC input), it is only connecting the light fixture with 110V 220VAC. But for the low voltage DC12V 24V wall wash lights, you need to prepare an extra power supply, the drawing of installation is as follows:

Speaking of installation, someone will definitely ask wall washer distance from wall. The placement distance of LED wall washers from the wall depends on several factors, including the beam angle of the fixture, the desired lighting effect, and the specific characteristics of the space. However, there are some general guidelines you can consider:

Beam Angle	wall washer from wall distance	reason
Narrow 10-30 degrees	1ft to 3ft	creates a more concentrated and focused lighting effect on the wall
Medium 30-60 degrees	3ft to 6ft	helps achieve a balance between coverage and intensity
Wide above 60 degrees	6ft or more far away	suitable for achieving a broad and evenly distributed lighting effect on the wall

Application

The high-power LED wall washer has an irradiation distance of 10-1 meters, which is very suitable for panoramic floodlighting of internal and external walls such as government lighting projects, commercial places, subways, elevated overpasses, building exterior walls, and architectural landmarks. Landscape buildings, outdoor plazas. Coloring of landscape objects, walls, and exhibits. Can adapt to various indoor and outdoor temperature and humidity environments. The colors are red, yellow, white, green, blue, colorful, and other effects.
