E75 motorway lighting upgrade - Belgrade

More than 1,300 street lights have been replaced with energy efficient ones on this busy motorway linking the Nikola Tesla Airport to the Lasta bus station in the city centre

In 2017, the city of Belgrade upgraded the lighting on the E75 motorway linking Nikola Tesla Airport to Lasta bus station in the city centre to increase safety, cost-effectiveness and environmental benefits.

The existing Onyx luminaires with high-pressure sodium lamps (400W) lighting the motorway were diffusing an orange hue, making it difficult to see the real colours at night. They have been replaced by Ampera Maxi luminaires mounted on the same posts at a height of 13.5m with a spacing interval of 62m.
With an installed power of 274W, they provide the required lighting levels for class M1 with a better quality of light, enabling the city to reduce energy costs by 38%. They also require no routine maintenance, with no need for cyclic lamp changes, which means less disruption for drivers and further savings for the city.

Equally important, these new modern LED fittings direct the light exactly where it is needed with excellent uniformity. They emit a crisper, white light ensuring excellent visibility, a better contrast and high visual comfort, helping to reduce traffic accidents, leading to safer roads.

The luminaires are managed by the newly installed Owlet Nightshift control system. This system enables the city to monitor and control the lighting network to manipulate operational burn hours, dim lighting at times of lower traffic flow, monitor faults and track energy consumption. This can be done on a unit-by-unit basis or globally.

The GL2 Compact was mounted in the ceilings of the underpasses along this section of the motorway, again increasing the quality of light for improved safety with less operating costs.

A total of 1,306 luminaires were replaced along this 18km long section of the motorway.

The local authorities are delighted with the new lighting solution which not only makes the E75 perceptively brighter at night, but delivers significant energy savings and a reduced carbon footprint.
