The KL-LED·D78 suits minor operations rooms, day-surgery theatres, obstetric theatres, emergency departments and treatment rooms with one table, in new builds and refurbishments. Its case is estate and environment. A ceiling lamp is part of the room, and the room decides whether one head on one arm will do its job.
Position comes first. The fixing point sets the circle the arm can sweep, so it should be chosen from the table outward: the head must reach both ends of the field, hold its place there, and park clear of staff when not needed. Other ceiling equipment shares that space. Pendants, monitor arms and anaesthetic booms need their own swing circles drawn on the same plan. Where an ultraclean ventilation canopy is fitted, the head sits in the clean airflow, so the ventilation supplier should agree on its position and shape.
The building work follows. Keling lists a ceiling height of 270 to 320 cm, which rules some rooms out at once. The column needs a structural fixing approved by an engineer, a certified electrical supply and a backup arrangement, since IEC 60601-2-41 expects light back within 5 seconds of a failure. In a refurbishment, the old fixing may not suit the new loads, and opening a theatre ceiling calls for dust control and a clean before the room returns to use. One head light from one direction, so a room planned for major open surgery should allow space and load on the ceiling for a second lamp later.
Estate directors, NHS procurement routes, and public works departments abroad will ask for the device class, the installation drawing, and a declaration of conformity. The manufacturer issues the conformity documentation those procurement routes require, and the enquiry team shares it.
