Over one thousand Tunable White luminaires deliver uniform, quality light across ten floors of retail and public space

eldoLED Drivers, DALI DT8, and LightShape Technology help bring the architects’ vision to life

ATLANTA, GA – December 11, 2019 – On November 29, 2019, the Forum Groningen opened its doors in Groningen, the largest city in the north of the Netherlands. The new building includes a ten-story multifunctional meeting place, library, art cinema, an exhibition, restaurant, and study room for small groups. Also, it is one of the largest public buildings with tunable white luminaires throughout the entire space that can be dimmed to 0.1% and provide continuous dynamic adjustment of the light from 2500K to 4000K throughout the day.

Using eldoLED® drivers supporting the new DALI Device Type (DT) 8 standard and with integrated LightShape technology, precise control of the color and light intensity were set using just a single DALI directive. eldoLED's DUALdrive digital LED drivers ensure that flicker-free, smooth and consistent dimming to 0.1% is achieved by each luminaire. The LightShape technology manages the color and intensity so precisely from luminaire to luminaire that any two or more of the thousand plus luminaires could be positioned side-by-side without any observable difference across the color and intensity range.

The original design by NL Architects in 2007 called for 1500 fluorescent luminaires. Eight years later, with a desire to improve sustainability, the lighting was redesigned for LED technology that could maintain the linear visual nature of the fluorescent fixtures and produce effects that simply weren't possible with the original technology. NL Architects, Lichtpunt Theatertechniek, TDE-lighttech, and eldoLED worked closely together through the process of design review, creation of a new luminaire, experimental test set-ups and ultimately installation and commissioning.
