Tridonic has added CLE Tunable White modules to its existing Tunable White range for round wall and ceiling luminaires. The modules incorporate an adjustable colour temperature which can be set from 3000K to 6000K with the luminous flux remaining constant.

Tridonic’s CLE Premium modules are designed for round wall and ceiling luminaires and are available as pre-calibrated sets. In addition to four or eight LED modules, which lead to module diameters of 261 mm, 401 mm or 541 mm, the sets contain low-profile LED drivers. The drivers provide various connection options via their digital interface: 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 to 100 percent. The colour temperature remains constant during dimming.

Depending on the LED module used, the luminous flux is 4 x 1150 lm, 4 x 2450 lm or 8 x 900 lm. System efficiency is up to 166 lm/W depending on the module size. The CLE Tunable White system requires no additional cooling and has a life of 50,000 hours. The manufacturer offers a 5-year system guarantee.

Light that addresses the needs of people and mimics light over the course of a day with its white tones has a stimulating effect on people’s well-being as well as increasing concentration and productivity. This is of great benefit not only in offices and educational establishments but also in retail and healthcare facilities. Current studies suggest that the right light can have a positive effect on disruptions in biorhythms and depressive moods.
