What is indirect light?
Definition
Indirect lighting is a lighting technique in which light is reflected within a space, thereby illuminating a larger area. It is created by the reflection of light and produces an effect known as an indirect light source. A characteristic feature of indirect light is the low contrast between light and shadow. A practical example is an LED light that provides lighting indirectly, for example through a window. Unlike direct light, which shines directly from the light source onto an area, indirect light spreads subtly and evenly throughout the room. Read more about direct light.

When do you choose indirect light?
If you wish to create more lumen in a specific space without introducing harsh lines and contrasts, using an indirect light source is an excellent choice. This is particularly true if you prefer an even and soothing atmosphere. Furthermore, indirect light is commonly used in other applications, such as driving lights, where the light is reflected to create an indirect illumination.
A balance between direct and indirect light
Can direct and indirect light be used at the same time? Absolutely. Although it may be tempting to illuminate a space exclusively with direct light to create a serene atmosphere, this results in sharp contrasts between light and shadow. On the other hand, whilst indirect light alone provides brightness, it can sometimes lack visual impact. The interplay of both light sources is crucial to bringing a space to life. The purpose of the lighting determines the desired lighting effect. Direct light shines directly onto objects or surfaces, whilst indirect light is created by reflection.
A clever lighting plan for Indirect Light
To make the most of indirect lighting, a well-thought-out lighting plan is essential. Ensure that you plan and carry out any electrical systems and structural modifications well in advance. Consider creating connection points for LED strips and other light sources to achieve the desired indirect effect. With a carefully devised lighting plan, you’ll be ready to bring the enchanting atmosphere of indirect light to life in your space.
