Maximum flexibility for shop window lighting is achieved if the infrastructure for lighting is located close to the facade. In this way, high brightness is generated on the front and sides of the displayed products. Track luminaires enable convenient repositioning of the luminaires if the display changes. A ceiling channel or the installation of recessed spotlights is ideal for mounting the luminaires unobtrusively in the shop window. Track with spotlights on the side walls is also suitable for illuminating the front shop window zone and creating dramatic shadow effects.
