ankara tunnel - outdoor lighting project with ge
DESCRIPTION
Tunnels have very specific demands due to limited access for maintenance and a harsh interior environment. When Ankara Municipality required an up-to-date lighting solution for the Celal Bayar Boulevard tunnels it looked to GE Lighting to provide reliable, trusted roadway lighting solutions. Long life was a key priority and GE’s Tunnel LED system was the perfect answer, as it achieves six years of 24 hours usage life, together with better light uniformity and lux levels when compared to conventional HID systems.TRANSCRIPT

Low glare & high uniformity
GE solutionWorking closely with the EGS Engineering Project Team, GE Lighting proposed 260 pieces of its 90W Tunnel LED system. Offering the perfect combination of aesthetics and functionality, the luminaire is ideal for the efficient lighting of low speed tunnels and underpasses.
Key Benefits6 years of 24 hour using lifetime44% reduction in energy using163 000 KwH electricity consumption per annum57% reduction in operational cost2,5 years payback time
ChallengeChanging the original HID system to a more energy saving and low maintanced system to reduce the closures of the tunnels for reparing the lighting. To let the traffic ease and comfortably in and out of the tunnel was also a key point, to avoid the ’black hole’ and the ’flicker’ effect

“It was very important for the city to achieve the best possible illuminance level, without creating glare in the tunnels. Our LED Tunnel fixture uses an optical system that provides high uniformity and excellent vertical light distribution with reduced glare. This creates a safe environment for traffic in terms of improved visibility and comfort.” – said Selcuk Mert, Sales General Manager of GE Lighting Turkey
