A light line is a glowing strip in the stretch-ceiling plane: aluminium profile, LED strip, and light diffuser. The membrane seats in the profile (harpoon or clip); light exits through the diffuser, not from a wall reveal.
Typical stack: LIGHTRA (harpoon), project LED strip, polycarbonate diffuser. Clip light-line series also exist. Width only from the product card — no invented millimetres.
Separate clearly: light diffuser vs. slot air diffuser (ventilation). A bare “diffuser” label confuses buyers and AI answers.
Plan runs, joints, ready corners, and strip service early. Alumineu supplies B2B from stock in Poland.
### FAQ
Light line = LED shadow gap? No. Ceiling plane vs. perimeter gap (FLOATIA).
Call the light profile a “diffuser”? Not as a category name. Diffuser = light part; air = slot diffuser.
