Stretching nearly one mile across the Bosphorus Strait, the Fatih Sultan Mehmet Bridge, also known as the Second Bosphorus Bridge, is a defining landmark on the Istanbul landscape. Named after the 15th-century Ottoman Sultan Mehmed the Conqueror, who conquered Istanbul in 1453, it is one of 3 bridges in Istanbul that connects Europe to Asia.
This motorway bridge has four lanes for vehicular traffic as well as an emergency lane in each direction. Approximately 150,000 vehicles pass daily in both directions. Built in 1988, the bridge had a lighting system consisting of 240 fixtures fitted with high-pressure sodium vapour lamps.
In 2015, after more than 25 years of service, the local authorities embarked on a rehabilitation project to enhance the aesthetics of the bridge and ensure an energy efficient lighting scheme was in place.
As the new luminaires would experience a great deal of vibrations and be exposed to harsh weather environments, they also wanted a robust solution that would ensure long-term performance and need minimal maintenance.
They chose the Teceo.
A total of 240 luminaires were installed on the existing poles at a height of 13m.
These low-energy LED luminaires provide a high light output, in line with international standards, to improve visibility on the bridge while cutting energy costs by 52%.
This was the first LED lighting project on a motorway in Turkey and it is a great success. Motorists appreciate the improved visibility at night while the local authorities are happy with the lighting system that sends a clear message about the city’s commitment to sustainability.
