Tridonic has announced the new CLE Tunable White modules with adjustable colour temperature that can be set between 3000K and 6000K, with the luminous flux remaining constant. The new modules are tailored to round wall and ceiling luminaires and are only available as precalibrated sets.

The sets contain four or eight LED modules, which lead to module diameters of 261mm, 401mm or 541mm, and low-profile LED Drivers. The drivers provide various connection options via their digital interface, including DALI Device Type 8, DSI, switchDIM and colourTEMPERATURE. This ensures a constant high quality of light with a CRI > 80 and small colour tolerances corresponding to MacAdam 3 across the entire dimming range from 10-100%. The colour temperature remains constant during dimming.

Light that addresses the needs of people by mimicking light over the course of a day with its white tones has a stimulating effect on people’s well-being and can help increase concentration and productivity.

This is of great benefit in offices, educational establishments, retail and health care facilities. Current studies also suggest the right light can have a positive effect on disruptions in biorhythms and depressive moods.

Depending on the LED module used, the luminous flux is 4 x 1150 lm, 4 x 2450 lm or 8 x 900 lm, while system efficiency is up to 166 lm/W depending on the module size.

The CLE Premium modules require no additional cooling, have a life of 50,000 hours and include a 5-year system guarantee from the manufacturer.
