In the Vasileostrovsky district of St. Petersburg, on Zheleznovodskaya Street, old sodium lamps were replaced with LED ones.

The 1.7 km long roadway was illuminated by 122 new generation lanterns. The supports and fixtures remained the same.
The lighting system of Zheleznovodsk Street runs within the boundaries of seven blocks. It consists of two parts: from Uralskaya Street to Baltic Jung Square and further to Cash Street. The first part is a driveway with sidewalks and hanging lanterns. The second is an intra-block passage, which is illuminated by lamps on supports. The work was carried out in two stages: first, the cantilever lights were changed, and then the suspended ones.
For the first time, lighting on Zheleznovodsk appeared in 1965. The last reconstruction was carried out in 2012. The savings from replacing the lights will amount to 600 thousand rubles per year.
