Tunable White system for Downlights – lighting scenes at the touch of a button

The second DLE PRE Tunable White Downlight system is precalibrated at the factory and has an adjustable colour temperature range of 2,700 to 6,500 K, so it covers the entire white range from warm white to cool white. Luminous flux remains constant at all times. The system provides a simple way to create dynamic lighting solutions such as Tunable White and human centric lighting applications.

The DLE G2 PRE Tunable White system for downlights available as a precalibrated kit consisting of perfectly matched components: a compact LED driver and a Tunable White LED module available with a luminous flux of 2,000 lm or 3,000 lm, ensuring both high quality of light CRI > 90 and high colour consistency (SDCM 3).

The system includes a dimmable two-channel DALI-DT8 surface-mount driver to which either a  digital control signal (DALI) or a standard pushbutton switch (switchDIM) can be connected. The light can be dimmed from 100% to 1% without any change in the selected colour temperature. The corridorFUNCTION can be programmed via a DALI-USB interface using masterCONFIGURATOR. This function can be activated manually by applying a voltage of 230 V to the switchDIM connection for five minutes.
