At night, the castle facade is illuminated by Tesis recessed floor wallwashers. The soft, even illumination of the facade is guaranteed by 24 of these luminaires whose lens wallwasher technology is unique on the exterior luminaire market. The luminaires themselves are discreetly sunk into the floor and provide optimal visual comfort thanks to a high glare control. The use of 35W HIT-CRI high-pressure metal vapour lamps ensures particularly low energy costs and long maintenance cycles.
