Within a general renovation plan regarding the existing lighting system of the NIK building right in proximity of its hundredth anniversary, the responsible authorities decided to make a general improvement through the installation of a brand new LED color changing equipment. The initial requirements involved the capability of the specified lighting fixtures to work at very low temperatures, quite typical during the long Polish winters. While in the previous lighting scheme only some details of the building were enhanced in white light, the new layout was required to offer, besides the possibility to highlight single details, also a uniform wall washing effect in bright, dynamically changing colors.
To do so, based on the lighting design of the Polish lighting company Prolight Sp. O.o., 29 units of Ruby Recessed in warm white have been embedded in correspondence of the square columns of the front and side buildings in order to emphasize them with a narrow ray of light up to the cornice. A general wall wash effect is then delivered with the help of 32 units of Powershine MK2 S in RGBW color configuration with spot optics. The powerful floodlights reach the entire façade with an even color distribution used, for instance, to reproduce the colors of the Polish flag in official occasions, or to enliven with bright colors the whole building complex at night. To complete the lighting design, 2 units of Jade 16 in warm white have been mounted on the corners of the upper gable to enhance its architectural features in a warm shade of white. A projection of the NIK founder Józef Piłsudski completes the layout in the festive occasions.
In order to comply with the project prerequisites, both JADE 16 and POWERSHINE MK2 S fixtures have been specified in the Polar Edition, which features an integrated de-icing system with electrically heated glass for a comfortable functioning even in the utmost severe cold weather conditions.
