What's the difference between sunlight and skylight?

Natural light is made up of two distinct and complementary components:

- The brightness of the sky 

- The sun's rays

Sky light

Diffused and soft, sky light provides between 500 and 5000 lux of illumination. It comes from the sun's diffusion and reverberation in the atmosphere. Sky light acts like a shower of light falling vertically from the sky. It provides stable, zenithal lighting. It's present whenever it's daylight, whatever the weather. 

Sunlight

Direct and intense, the sun's rays provide between 20,000 and 100,000 lux of illumination. They cross the atmosphere in a straight line. Sunlight acts like a powerful spotlight moving across the sky, turning on and off as the weather dictates. The sun's rays are present intermittently.

How can I get more light from the sky?

Without direct sunlight, the Reflector reflects light from the sky. This light is diffuse and of low intensity. It is transmitted over a short distance. In this case, the maximum distance between the reflector and the room to be lit is 3 to 4 m.

How can I get more sunlight?

When the Reflector is in the sun, it can reflect its rays back into the room to be lit. This direct sunlight is concentrated and intense. It travels a long way. However, the movement of the sun in the sky means that the rays quickly leave the window if the distance is too great. That's why we recommend a maximum distance of 5 to 6 m, 10 m for a motorized reflector and 25 m for a motorized reflector with solar tracking or a curved reflector.
