Istanbul needs to be bright because it has a touristic importance of being cultural, artistic, political and commercial center in the world and in Turkey. In addition, good illumination at night is essential for people’s safety. Therefore, it is of great importance to maintain the existing lighting facilities, build new facilities in the necessary areas and maintain these newly built facilities in good condition.

Küçükyalı Tunnel Maintenance and Repair Activities

The 268 meters long tunnel located in the sidetrack of Bostancı-Küçükyalı is remarkable with its sense two directional traffic. Although maintenance was performed at various times after the construction of the tunnel and the lighting was improved, the power consumption was high since it was a system where traditional bulbs were used. Furthermore, the lighting armatures which broke down by time and which are irreparable were renewed in early 2021 by being replaced with using totally 206 LED asymmetric tunnel armatures. Armatures with brightness level of three different powers depending on the sun light were used gradually in the exits and entries of the tunnel in order to provide sight adaptation of the drivers and the armatures used were selected with color hotness of 4000 Kelvins.
