What is Wallwasher?

With the widespread use of LED technology, we see colorful LED Wallwasher luminaires on the outside of many buildings. While wallwasher applications give a modern appearance to the building, it adds a different atmosphere when applied with its right color preference.

Wallwashing is a popular lighting design technique used to illuminate large surfaces.

Wallwasher means wall washer. However, the washing process does not mean cleaning.

Instead of focusing on a specific area of ​​the wall and shining the light, the luminaires that light up a region of the wall are called Wallwashers.

The most common use of Wallwasher in our language is Wall Painting.

It is mostly used in public buildings, cultural buildings, museums, galleries, or in conjunction with contemporary architecture in landscape lighting.

Indoors are often used to create relaxing areas, to make rooms look brighter and look higher.

Here are 7 properties you should look out for before buying an LED Wallwasher.


Power is the most important factor that determines the LED Wallwasher’s projection distance. Generally power 18W, 24W, 36W, 48W and so on. but different power options can be countered. Given the thermal performance, it can be said that a 1-meter wallwasher should not exceed the 36W power limit. Of course, this value can vary depending on the case, ie the structure of the cooler body. The body, which can not provide adequate cooling, can cause the luminaire output to decrease over time.


You may need DC or AC voltage depending on the project. Wallwashers with built-in AC power supply can operate with 220V or 110V. However, some Wallwashers may require 12V DC or 24V DC tensioning.
