Tunable White

The sequence of daylight

Dynamic colour temperatures based on nature’s example

Tunable White for everyone

Natural daylight and its lighting dynamics lay the foundations for our well-being. However, we spend most of our lives in artificially lit rooms. A lack of daylight has been linked with causing a lack of information needed for the human rhythm to function properly. That is why we should not regard artificial light as a rigid and homogeneous installation, but rather as a “dynamic design of a visual indoor atmosphere”.
Optimal lighting takes into account different situations in rooms but considers our needs as humans as a priority. This requires a continuous adjustment to the individual’s vision, work tasks and activities, as well as changes according to the weather situation and the time of day and year. A light that is intelligently controlled in this way increases motivation, concentration and quality of life in any office, production hall, public building or sports and leisure centre. In addition, Tunable White allows rooms to be lit properly at the press of a button and is therefore multifunctional.

Focus on personal needs: Individualisation and concentration

In the Human Centric Lighting concept, the light is tuned to our individual needs as humans, which vary according to the time of day and year, age, activity and state of mind. For example, as age increases, the need for higher luminance also rises. A favoured lighting set-up also depends on the task at hand. Whereas neutral white light promotes concentration, warm white light creates a calmer atmosphere for creative activities, brainstorming or relaxed breaks.

Promoting well-being and health

The health-enhancing properties of light have been a hot topic for years. Certain colour temperatures can have a positive effect on the recovery process and general well-being, which are particularly beneficial for hospitals and care institutions. In addition, colour temperatures are also essential for the objective perception of rooms. Depending on whether the proportion of warm white or cool white light is predominant, the ambience is perceived as either cosy or cool. This can go so far that some people feel cold in cool white light.

Tunable White for objects

As a design element, light is capable of making materials, exhibitions and entire rooms look utterly different. Colour temperatures give rooms a characteristic atmosphere and underline the beauty and brilliance of different objects and surfaces. With the right light spectrum, colours can be emphasised and powerfully presented. Works of art are also perfectly staged, as are jewellery, fashion or design elements and materials.

One of Tunable White’s great advantages is that a lighting atmosphere can be completely changed at the press of a button, meaning that it is even possible to bring a sense of daylight into rooms and buildings that have no windows.

Presenting objects authentically

Tunable White not only reproduces colours authentically, but its effects can be further amplified using the right colour temperature. For example, it can make food look more appetising and clothes look to be of higher quality in shops. If the shop’s range changes, the rig-ht light spectrum is always available at the touch of a button, touch panel, smartphone or tablet. This flexible adjustment makes it easy to test how products look in different lighting moods. As a result, it is easier to see, for example, how articles of clothing appear in various environments – from a brightly lit gym to the park at sunset.

Studying nature illustrates how even the slightest changes in light can influence our moods and how we perceive objects. This notion is at the heart of Tunable White Technology, which is based on the natural colour changes in the light over the course of the day.

As humans, it is not uncommon for us to spend most of our day in enclosed areas. Seamlessly adjustable colour temperatures – from cool white to warm white – bring natural lighting effects, with all of the associated advantages, from outside to inside, and make it possible to properly target individual needs and situations. As a result, Tunable White supports the concept of Human Centric Lighting (HCL), which puts people at the heart of lighting design. As well as perfect conditions for reading and working, HCL is primarily focused on the circadian rhythm, which controls, among other things, our body clocks. As studies have shown, cool white light with a high proportion of blue light has a stimulating effect and promotes concentration, whereas warm white light is calming. Therefore, Tunable White creates an environment that helps us in a natural way – just like daylight.
