With the right colour temperature and illumination it is possible to feel comfortable despite artificial lighting whether you are working in an office, studying at university or recovering in hospital. The TRIDONIC “Tunable White” solution simulates natural daylight and can adapt to personal requirements. For example, the well-being of patients in healthcare facilities is improved and the healing process is accelerated. Students and office workers also benefit from this lighting system as they are able to concentrate for longer and are more productive.

With TRIDONIC Tunable White, the colour temperature can be set to any value. The colourSWITCH mode available for spotlights enables the light colour to be selected specifically for the application. This is useful particularly in the retail sector as it allows the merchandise to be presented in the most appropriate light. The system can also be dimmed between 100 % and 15 % (10 % for LLE and QLE) without shifting the colour temperature. The system is precalibrated at the factory and can be used immediately without any further adjustment.

LED Driver

The TRIDONIC PREMIUM Tunable White system is available as a kit with LED modules and a pre-configured LED driver. The set enables the sequence of daylight to be simulated in spotlights as well as in linear and planar lighting.

LED Module

  • Tunable White for spotlights: 2,700 - 6,500K with a CRI of > 90
  • Tunable White for linear, decorative and planar lighting: 3,000 - 6,000K with a CRI of > 80

Typical Applications

Office and Education
  • Simulation of the changes in natural light throughout the day
  • Increased concentration and productivity

Following timelines show various ways of modifying colour temperature in a biologically effective manner.

The upper timeline and the series of photos above show variation that is synced with daylight. The lower timeline uses biologically effective light to speed up the inner body clock in the morning as the bright blue rich light signals us to be awake and alert, this has a positive impact on sleep behaviour. The typical afternoon dip in energy levels is also compensated by an invigorating light component. At the end of the day, the soft red rich light tells our bodies it is time to relax and prepare for sleep.
