How they are grouped
- Surface mounted — sits on the surface as a clean line. Under-cabinet, shelf and coving.
- راحة — sits in a groove so only the light shows. Plasterboard and trimless.
- موقوفة عن العمل — hangs from cables, lit on one or both sides.
- الزاوية — a 90° section for wall-to-ceiling or wall-to-floor angles.
The position decides the profile. The strip, cover and finish follow from it.
