Light and perception quality of a luminaire are not only dependant on its brightness, but especially its colour temperature. Tunable white opens a world of possibilities regarding precise lighting under changing requirements: it makes it possible to achieve variable settings ranging from warm white via neutral to cold white. This allows for an optimal lighting level of goods, such as seasonal produce for instance, in sales rooms and shops.
It also finds its use in offices, schools and health care facilities, where it can achieve an imitation of the changing lighting conditions outside. This has a positive influence on the wellbeing of those who experience it. The fluent change from relaxing warm white to activating cold white helps stabilise the inner biological rhythm and promotes productivity and general wellbeing.
