More than 220.000 bulbs are illuminating the city Vienna in Austria.
Currently the Viennese magistrate is preparing for a street light retrofit
action. More than 5000 old fashion lights are going to be replaced by
energy-saving LED luminaries.
Old balloon lamps, which are mostly installed on the Danube
Island and he different parks will be replaced in the following weeks by much
brighter and modern LED. Those are more favorable in energy consumption, are
long living and don’t emit UV light.
