In order to replace the old illumination of the castle based on warm white light discharge lamps dating back to the 80’s, a new lighting system has been recently planned, installed, tested and fine-tuned at Hellenstein Castle. The planning phase was very long and involved the German lighting planner Martin Schepers, the delegate of Heindenheim City Hall Ralf Käpplinger along with the regional sales representative of the company .hess, Jürgen Günther, and the lighting designer department of GRIVEN.
As Heidenheim's main landmark can be actually seen from any direction, the lighting scheme agreed by all the lighting professionals involved promoted an all-around illumination, which could be able to enhance and make the castle visible at night from every point of view, without any dark spots. Moreover, the lighting scheme should remark the beautiful architectural features of the castle with a well diffused, colour changing, tunable system with an eye on a considerable energy saving approach. This was the main target of Ralf Käpplinger as spokesperson of the city municipality’s requirements.
The renowned architect from Dortmund, Martin Schepers, who boasts a wide experience in illuminating castles and buildings around Germany, based the preliminary calculations and computer simulations on the official lighting requirements and on his experience, but also on photographs of earlier on-site spotlight tests. "Preliminary calculations are necessary," he says, "but in the end you always have to see the final result "live” in order to implement the ultimate changes and adjustments."
About half of the 35 spotlights installed at the castle have new locations now, also owing to the fact that the previous positions on the roof of the close Güttinger building were not available any more. In order to light up all the sides of the huge building, the chosen LED fixtures were installed all around the castle according to the different architectural layouts and the result desired.
