Natural light is spread at the University of Arizona, US.
The University has chosen to install SP4 at the new premises for the Department of Health Sciences and Innovation. It is a prominent research university that, in addition to testing Parans system for new uses, also will use it to get the building approved under the LEED environmental certification system.
The natural light is spread in a hall way and a lounge with the help of the so-called Point Light luminaire. The collector on the roof is of the SP4-8 model, which means that it has eight light points. From the collector, 100-meter-long cables lead the light, with maintained light intensity, through several floors to the rooms.
