| The city of Hódmezővásárhely in south-east Hungary has replaced all of its street lights with more than 6200 LED luminaires supplied by Tungsram-Schréder, a Hungary-based member of the Belgium-based Schréder Group.
The new lighting scheme is expected to generate energy savings of between 35% and 40% for the city, and will also dramatically reduce maintenance costs. It has also enabled the city to cut CO2 emissions by 415 tonnes - the equivalent of turning off approximately 6,500 television screens or 8,000 washing machines.
Hódmezővásárhely launched a tender in 2010 to replace all of its street-lighting installations. The local authorities wanted an energy-efficient and environmentally-friendly solution that would make use of modern technologies.
After analysing the different products available on the market, the local general contractor (E-OS Innovative) selected Tungsram-Schréder to develop a high-quality, cost-effective lighting scheme for the city.
Tungsram-Schréder developed two luminaires- the Sapphire LED and the Aresa LED. Over 6,200 luminaires have been installed throughout the city, dramatically improving the urban landscape.
The lighting manufacturer worked closely with the local authorities on this project since, as it points out, simply choosing a LED luminaire will not guarantee a successful installation. Each city has different lighting infrastructures: various parameters such as the road surfaces, electrical network, and pole distances and heights, need to be considered.
Bjorn Brandt, General Manager at Tungsram-Schréder, explains: “The trick is to create a so-called lighting master plan, street by street, which will ensure that the long-term goals and expectations are really achieved. The final solution must be durable and should only require minimal maintenance.”
The new lighting scheme has improved lighting levels, making roads and public spaces more secure. The luminaires are fitted with LEDs with a carefully-selected color temperature of 4200K. The aim, says Tungsram-Schréder, was “to provide a white light with excellent visual comfort and with a high color-rendering index which creates a much more pleasant environment - buildings have recovered their true colours!”
A survey carried out after the first installation revealed that the inhabitants are delighted with the new lighting, especially in terms of visual comfort.
