Light always has a story to tell

the eye instinctively turns towards the light in order to see.

Lighting has a great significance to our well-being, health and safety. This is why it is such an important element in building and interior decoration.

Light is electromagnetic radiation invisible to the eye. Light only becomes visible when it meets a surface. Colors are formed by waves of different lengths, and when combined together produce white light. When white light is refracted through a prism, the whole color spectrum becomes visible, as in a rainbow. The human eye is only sensitive to the range of the “visible light” wavelengths, which is between 380 nm and 780 nm. The extreme ends of the scale being ultraviolet (UV) and infra-red (IR) light.

The human eye is perfectly able to adjust to the great variations of luminosity found in nature, from moon light (1 lux) to bright sunshine (100,000 lux). In artificial lighting conditions, we usually have to compensate for minor variations, from general lighting (1-2,000 lux) to working light (200-2,000 lux).

Our vision is based on light. The eye instinctively turns towards the light in order to see. Some 80% of all information is received through the eye.

When we step into a room, our eyes circle it guided by light, and the light tells us the story of the room: its shapes, colors, architecture, decoration, ornaments etc. A good lighting makes seeing easy and pleasant. It is a treat for the eyes.
