October 8, 2026 · RiGeBa Lighting Team · How-To

LED wall washers are a popular choice for illuminating facades and ballrooms due to their energy efficiency, long lifespan, and versatility. However, choosing the right LED wall washer can be a daunting task, especially when it comes to beam angle, throw distance, and evenness.

The short answer

For a 10-meter throw distance, a beam angle of 30-60 degrees is suitable, and the 24pcs 1.5W RGB Outdoor LED bar can be used to achieve the desired level of evenness at a price of USD 49.

What is the ideal beam angle for a facade?

The ideal beam angle for a facade depends on the throw distance and the desired level of evenness. A narrower beam angle is suitable for longer throw distances, while a wider beam angle is better for shorter distances. For example, the 24pcs 1.5W RGB Outdoor LED bar has a beam angle that can be adjusted to achieve the desired level of evenness.

How do I calculate the throw distance for my LED wall washer?

To calculate the throw distance, you need to consider the height of the facade or wall, the width of the area to be illuminated, and the desired level of brightness. A general rule of thumb is to use a throw distance that is 1-2 times the height of the facade. For example, if the facade is 10 meters high, the throw distance would be 10-20 meters.
