The IDESTO recessed wallwasher is predestined for rooms with suspended ceilings and limited installation space thanks to its shallow installation depth and the ability to swivel the luminaire head. In order to achieve highly efficient and extremely effective homogeneous illumination of vertical surfaces, a special form of light control is required. Geometry plays a particularly important role when using a point light source (so-called COBs). The light extends evenly from the ceiling to the floor and provides glare-free lighting over an impressive width. The spring system makes installation and removal simple and uncomplicated, while the swivel angle of up to 15° allows easy readjustment.
