The better our daily routines are adapted to this rhythm, the more comfortable we feel and the better our performance becomes. Daylight is the signal transmitter that synchronizes our internal rhythm with the natural course of the day. LUCTRA® by DURABLE is the first biologically effective lighting system for the office environment that transfers these findings to daily life. Comprising table, floor and pendular luminaires in two designs and equipped with latest LED, LUCTRA delivers a very uniform and thus fatigue-free illumination to the workplace. Operated by the intelligent VITACORE® electronics the light color and light intensity can be adapted to the personal well-being at any time. The intuitive technology remains discreetly in the background. Thus LUCTRA® supports concentrated, relaxed and productive work effectively.. The VITACORE® app turns LUCTRA® into a flexible lighting tool. After answering five simple input questions it generates a personal 24-hour light curve for the user, which automatically changes the light intensity and light colour, simulating natural daylight. These pre-settings can be corrected and adapted to personal preferences at any time via simple graphic elements. The app transmits the personal lighting profile onto every LUCTRA luminaire. This makes LUCTRA® the ideal lighting system for modern office concepts with flexible workplaces.
