Open plan spaces that take advantage of FABRILum's combination of exceptional quality general illumination and superior acoustic performance may be susceptible to the "cave effect" in situations where the mounting height of the luminaires is substantially lower than the ceiling height.
The dark space above suspended luminaires may cause occupants to perceive that the ceiling is lower than it actually is, essentially acting in opposition to the reason for having an open plan design in the first place.
Research confirms what designers observe: bright ceilings appear higher than dark ceilings, irrespective of ceiling color or the brightness of other room surfaces. That dark void doesn't just look unintended. It literally diminishes the perceived height of the space itself.
The solution: FABRILum Indirect Lighting Kits
Adding indirect illumination will eliminate the cave effect to deliver the complete immersive experience your design intended. FABRILum Indirect Lighting restores perceived spaciousness by bouncing ambient light off the ceiling above, completing what the architecture set out to achieve.
FABRILum Indirect Lighting:
Each kit pairs an aluminum extrusion (for clean, easy mounting) with a clear lens (simple to dust and maintain). It integrates seamlessly with every FABRILum configuration: rectangle, circle, and bullnose.
