The Middle Ring Expressway, located at Suzhou Hi-Tech Zone has transformed into the most brilliantly luminated municipal road in Suzhou city. With a total investment of RMB 22 billion, the roadway was equipped with around 2,000 sets of OSRAM OLUX™ LED Spot H with 4000K color temperature. In addition, around 10,000 sets of OSRAM XTRA Liner DC were used to achieve different lighting effects by changing the high powered LEDs. The seamless lighting effects are operated by e:cue control systems, including Butler S2, LCE 2 and RDM Isolater that control around 10,000 sets of OSRAM XTRA Liner LEDs, which produce identical colors simultaneously.
