A shadow gap is the narrow reveal between stretch-ceiling membrane and wall. With an LED strip in the profile, that gap becomes a soft perimeter light source: the ceiling edge appears to float off the wall.
The FLOATIA series is built for this job: aluminium profile in a harpoon system, LED shadow gap, channel for the strip. It is not a freestanding luminaire and not a light line in the membrane plane — light exits the perimeter gap.
Plan power, driver access, and strip service early. The profile sets geometry; strip and light diffuser are project choices. No invented millimetres here — see product cards.
Alumineu supplies FLOATIA B2B from stock in Poland. Related: shadow gap without light (INVISIA) and light lines (LIGHTRA and others).
### FAQ
LED shadow gap vs light line? Perimeter light from the gap vs. a glowing line in the ceiling plane with profile and light diffuser.
