eldoLED Releases Industry's First DiiA Certified DALI-2 DT8 Tc Drivers

Acuity Brands, Inc. announced that eldoLED®, a world leader in designing and manufacturing intelligent drive solutions for LED-based lighting systems, has received the first Digital Illumination Interface Alliance (DiiA) certification for DALI Device Type 8 (DT8) color type Tc drivers.Courtesy of Forum Groningen: featuring over 1000 tunable white luminaires using eldoLED's DALI-2 DT8 compliant technology. Precise calibration of color and intensity at the driver level makes all the difference in a tunable white installation.

•    LightShape: intuitive colour temperature and intensity control
•    DALI-2 Device Type 8 (Tc) compatible for simplified commissioning
     of tunable white applications
•    Hybrid HydraDrive: provides the smoothest flicker-free high-performance
     dimming to zero for every fixture
•    Configurable design to work with most constant current LED modules
     and arrays, while providing a connection point to integrated peripheral
•    NTC interface for robust thermal management

•    Industry-best dimming performance for your fixture/application
•    Wide application area thanks to fully configurable dimming curve
•    Perfect for tunable white applications

Drivers using the DT8 protocol, also known as DALI 209, can use a single DALI short address to control two or more outputs. This can yield cost, space and manpower savings for LED system installations when using both RGB/W color changing and tunable white driver technology (DT8) within one fixture. This technology allows the end user to change the light color, color temperature and intensity of LEDs in a room or across a lighting system.

"eldoLED is the first in the industry to receive a DiiA certification for these types of drivers, marking a significant technology advancement for using DALI to specify and control color in LED modules," said Gilles Abrahamse, Acuity Brands Lighting Vice President of Digital Luminaire Components.

"DT8 certification is the culmination of eldoLED's latest effort to elevate color science and is a significant step forward in our quest to bring digital solutions to market, simplify solution development, and drive the quality of light in LED systems," said Chad Stalker, Vice President Global OEM Marketing and Sales. "Reducing the number of addresses simplifies design and commissioning as evidenced during eldoLED's Groningen installation."

Use of the DT8 driver technology is certified in the DUALdrive 562 and 20W LED driver models from eldoLED. Other DUALdrive products and certain LINEARdrive products are currently in the DT8 certification process. eldoLED drivers are interoperable with many LED systems.

eldoLED will demonstrate the full capabilities and advantages of DT8 at Light+Building in Frankfurt on March 9-13, 2020 and at LEDucation in New York City the following week. For further information, please contact a local eldoLED sales representative.
