LEDGEAR® 50W DALI DT8 dimmable drivers

Colour temperature control technology is essential for Human Centric Lighting that supports wellbeing, brings health benefits and increases productivity – and on top, is a beautiful design element.

Kinglumi has a wide range of Tunable White luminaires, developed specifically for dimming and tuning of white colour. While the LEDGEAR® C7 & C8 Tunable white DALI DT8 LED drivers is the heart of tunable white lighting. It allows dimming and changing of color temperature through DALI-2 application controller or through two push-dim buttons. The driver works as a one address DT8 driver, or 2xDT6 in one address.

LEDGEAR® C7 & C8, are independent ECG, design with through wiring and super large wiring space, saving a lot of time and effort on the actual wiring work on site. Big push-fit looping connectors are quick to connect cables with, supporting also various wire thicknesses. Wires are secured to the driver with click-on cable clamps, and strain relief cover clicks on effortlessly securing the connections without any need for screws.


     For Tunable White as well as for 2-channel use (e.g. warm white/cool white; direct/indirect lighting)

     For panel light, troffer and area light in office and education application

     For spot light and downlight in retail and hospitality applications
