Revolutionary Tunable White (TW) phase control dimmer that can regulate both the lighting level and colour. For use with SG TW LEDDim luminaires. Until now, Tunable White has only been possible with DALI DT8, which requires a DALI installation. With TW LEDDim Smart, all you need is a normal power supply. Control manually or via the LEDDim app. In order to change the colour temperature, simply double click on the rotary switch. The 4 buttons allow you to save the applicable setting, which can be recreated at the click of a button.When using the SG Smart Gateway, it is also possible to set a daylight sequence which changes colour and intensity throughout the course of the day. You can then choose a standard rhythm, or you can set your own.
