Recessed Downlight SLV NUMINOS DL S Black/Chrome 8.6W 4000K 750 lm 1003822

SLV NUMINOS DL S, article 1003822, is a fixed recessed ceiling downlight in black with a chrome cone. It is not a tiltable MOVE spotlight: this article’s data line and the Ø 8 × 5.2 cm body match the fixed S DL, not the larger MOVE housing. The body is aluminium and the optic is polycarbonate. The LED driver is not in the box.

Cut-out and the ceiling void

The visible diameter is 8 cm and the body height is 5.2 cm. The cut-out is round, 6.8 cm across, and the product card asks for 5.5 cm of installation depth. Before cutting, compare 6.8 cm with the planned opening and 5.5 cm with the free space above the ceiling. The fitting is for recessing into a flat ceiling only, on a normally flammable or non-flammable surface. Do not cover the heat sink with insulation, and leave air around it. The allowed ambient temperature is −20 °C to +40 °C.

The built-in LED uses 8.6 W and delivers 750 lm at 4000 K, CRI 90, with a 40° half-beam angle. That is neutral white and a medium beam. Colour temperature cannot be switched, and there is a single light outlet. UGR is 19 or below. Lumen maintenance L80B50 is at least 50,000 h. The source is not a user-replaceable bulb: only the manufacturer, an appointed service technician, or a similarly qualified person may replace it.

Supply and limits

The fitting is protection class III and runs on safety extra-low voltage at a constant 250 mA. The manual requires a suitable LED converter, for example SLV 1004055, 1004058 or 1004067, at 250 mA and at least 8.6 W. Connection is for a qualified electrician. The rating is IP20/IP44, and the manual limits use to indoors. IP20 means no protection against water, so this is not a bathroom or outdoor fitting. Net weight on this EAN’s card is 0.165 kg.

Which ceilings

A flat black ring and a chrome cone give a modern, spare outline. Use it where the ceiling can take a 6.8 cm hole and 5.5 cm of depth: living room, bedroom, kitchen, dining room, hall, corridor, wardrobe, stair, office, study, hotel or shop. It does not replace a mirror light or a reading lamp beside a chair.
