The KL-LED·STZ4 suits minor procedure rooms, outpatient and ambulatory surgery suites, endoscopy rooms and small theatres in clinics and district hospitals. Its case is estate and environment. In many of these rooms, the building decides what can hang from the ceiling, and a single head on one column is the arrangement that fits.
Start with the ceiling. Keling lists 270 to 320 cm for installation height, and the fixing has to reach the structure, which in a converted room may mean a steel frame across the void. One column carries one arm set, so the load and the sweep are those of a single head, and both are on the installation drawing. The sweep matters in a small room, because the arm shares the air above the table with an anaesthetic pendant, ventilation grilles and sometimes a monitor arm. Drawing those paths on the room plan before ordering avoids a clash on fitting day.
Next comes the light itself. The single head is listed at 160,000 lux at 1 m over a 10 to 28 cm field, with a 150 cm depth of illumination across a 70 to 140 cm working distance. Skin lesions, hernias, carpal tunnel releases and vasectomies sit within that. Endo mode at 10,000 lux supports scope work and the quiet minutes of setup. At full output, heat output is up to about 512 W/m² based on the listed ratio. The electrical side needs one 110 to 240 V supply with a 120 VA maximum draw and a backup route agreed with estates.
Estate managers, NHS procurement routes, and tender committees abroad will look for the declaration of conformity, the class it states, and an IEC 60601-2-41 test report. The manufacturer issues the conformity documentation these procurement routes require, and the enquiry team shares it.
