Wall washers have a very high light output and are suitable for applications such as facade lighting. They are also robust and waterproof, so they are great for outdoor use. Because of the focused light beam (+/- 30 degrees), an LED Wall washer is very suitable for targeted facade lighting and lighting of objects. The color rendition of these wall washers is very good with a CRI of 80. If you are looking for a cheaper and less bright LED bar, we recommend using our LEDBar Pro series. See for this the category "Waterproof LED Bar 12V".
