What defines a good wallwasher in lighting design?
Wallwashing provides uniform vertical illumination. It improves the perception of space, highlights materials, and creates balanced general lighting. However, correct wallwashing requires dedicated optics and careful installation.
Wallwasher optics
A professional wallwasher uses a specific asymmetrical optic. It projects light evenly from ceiling to floor. The beam avoids dark zones near the ceiling and prevents bright spots on the lower wall. It provides a soft gradient of light without visible shadows or scalloping effects.
Installation recommendations
Correct installation is essential. The typical distance between the luminaire and the wall is 200–500mm. The exact position depends on the ceiling height and the wall material. Luminaires should be installed in a continuous line or carefully calculated pattern to ensure beam overlap and uniform coverage.
Wallwashers on track — additional flexibility
A key advantage of track-mounted wallwashers, such as Caro AS, is their adjustable position. In spaces with different ceiling heights or specific wall finishes, the wallwashing effect can be easily adapted by moving the luminaire along the track. This allows precise control of the starting point of the light on the wall and ensures a uniform result — even in challenging architectural conditions.
Common mistakes
Incorrect wallwashing often happens when standard downlights or wide-beam luminaires are used near walls. This creates bright spots on the floor, uneven light on the wall, and high glare. Without the correct optic and positioning, the wallwashing effect is lost.
Caro AS wallwasher
Caro AS from Karizma Luce is designed as a dedicated wallwasher for track systems. It provides a uniform vertical beam with high efficiency and glare control. It integrates into the Caro product family and is suitable for retail, galleries, hotels, or residential spaces where flexible wallwashing is required.
For other wallwasher solutions from Karizma Luce, discover Amata M AS, Dea Hestia S AS, or Dea Hestia M AS — all designed for precise vertical illumination in different project scenarios.
For best results, wallwashing layouts should always be tested on site. Minor adjustments in distance, spacing, or luminaire position can significantly improve uniformity and visual comfort.
