Amersfoort is a renowned eco-city. The city makes considerable efforts to maintain high standards of social and environmental sustainability. These concerns were at the forefront when the city chose the Aresa luminaire for a luminaire replacement program in their suburbs. The Aresa offers high-performance photometry with low energy consumption and optimum glare control. A total of 556 luminaires equipped with 24W and 36W compact fluorescent lamps have been installed.
