The existing lighting system at the University of Stuttgart library was nearing end of life . The impending ban on fluorescent lamps meant that it was not longer practical to continue using the exiting fittings . The lighting formed an integral part of the ceiling structure and could not be easily removed without compromising its stability .

RIDI Group produced a re-engineered light fitting that retained the original dimensions, structural support and lighting performance of the original . In addition the new luminaires reduce energy usage and reduce maintenance . Countless hours of downtime in the library were saved compared to having to replace the complete ceiling system .
