Innovative lighting solutions for a new urban district
FOUR Frankfurt is currently the largest urban development project in the Main metropolis – a district that combines living, work, leisure, and shopping. In close collaboration with the architects from UNStudio and HPP, as well as lighting designers from a·g Licht and Bartenbach, Zumtobel developed a well-thought-out lighting solution that unites urban planning vision, functionality, and architectural impact. The goal was to create a lively, safe, and identity-defining atmosphere through the use of lighting.
Architecture icon showcased with light
A special highlight is the illuminated "frames" on the four towers: vertical light elements that span the entire height of the building. A total of 1,200 IP-protected special luminaires have been precisely tailored to the architecture, allowing for dynamic DMX control with various light colors. The installation provides the ensemble with a strong visual identity at night - subtle, glare-free, and tailored to the urban environment.
Light art indoors: waterfall & starry sky
Zumtobel is setting standards indoors, too – for example, with a 23-meter-long light waterfall composed of 360 luminaires in Tower 4. The sculptural installation with a moiré effect uniquely showcases movement, space, and light. In Tower 1, 1,300 freely arranged SUPERSYSTEM II downlights create a 'starry sky' that enhances the atmosphere of the entrance area. Both installations are outstanding examples of applied light art, both technically and in terms of design.
15,000 intelligent luminaires provide maximum light quality in the office
Approximately 15,000 custom-made SLOTLIGHT infinity minicell luminaires are employed in the office towers. They flexibly adapt to different workplace scenarios and times of day thanks to tunableWhite technology. Polygonal floor plans with curved light lines were also implemented with high technical precision. Zumtobel hasn't just provided ideal working light but also ensured sustainable use over decades - functional, energy-efficient, and aesthetically compelling.
"The high value placed on lighting at FOUR makes it a real flagship project"
