Whether used on their own or in combination with BASO 2.5 system components, the different models of our CURVE and CIRCLE systems allow you to create new lighting concepts with a variety of shapes and visual effects-without sharp edges or angles. The curved channels let you draw figures on the ceiling such as circles, waves, or rectangles with rounded corners. You can also match the profile arcs to the architectural contours making them well suited for structures with a need for lighting that is both pleasing and unique.
