Special colours
Colours decisively influence the effect of
rooms and buildings. They support and
round off an architectural vision. That
is why we offer a vivid colour selection,
giving you the greatest possible creative
freedom and adapting to your design.
For the most popular XAL product
families, you can choose between subtle
Classic Colours and strong Trend Col-
ours, as well as special decorative gold
and bronze tones.
TW – Tunable White
Changes in light colour have a powerful
effect on our mood. Tunable White allows
the colour temperature to be shifted
smoothly from 2700 K (warm light) to
6500 K (cool light) to dynamically adapt
the lighting to the time of day or type of
activity.
Light scenes
Modern lighting management sys-
tems can call up different lighting
scenes depending on the situation.
Cold white light contributes to ac-
tivation during the day, while warm
white light sets the mood for rest and
relaxation in the evening. Lighting
scenes for different areas of a hotel
or restaurant are also possible, such
as indirect ambient lighting, accent
lighting, and high luminous intensities
for optimised illumination of meals.
The CWD option offers a smooth
transition of the colour tempera-
ture from 3000 K to 1800 K while
simultaneously reducing the light’s
intensity. This is like an incandescent
lamp’s (see graphic) dimming char-
acteristics. The reduced illuminance
produces a very warm colour tone of
light, offering a balanced work light
during the day and a relaxing light-
ing atmosphere in the evening. The
CWD colour temperature curve runs
within the comfort zone (see Kruithof
curve).
