Żoliborz has also decided to change its current lighting system. Along Anna German Street 14 street lamps of the latest generation, Tiara LED from Lena Lighting, have been installed. The devices are controlled by an integrated DALI system which, compared to an analogue interface, is versatile: it connects to other systems, collects data on possible failures, is less sensitive to interference and has a better signal. These advantages translate into reduced lamp failure rates and increased safety for all road users - pedestrians, cyclists and car drivers alike.
