SLV NUMINOS L CL DALI 1004603 Surface Ceiling Spot black LED 28 W 2700 K 36°

NUMINOS® L CL is a surface-mounted ceiling spot 10 cm across and 21.3 cm tall, in matt black. It needs no ceiling cut-out – it screws to the surface – and still has the optics and control of a recessed fitting.

DALI and Touch control

This is why you choose this variant over a cheaper one. The fitting supports DALI – the bus of specified installations, where every luminaire has an address and belongs to room-wide lighting scenes. The manufacturer lists a second technology alongside it: Touch, i.e. dimming from an ordinary push-button when there is no bus. The same fitting therefore works in an office with a control system and in a flat without one.

The light

A colour temperature of 2700 K is noticeably warmer than the 3000 K usual in spotlights – closer to incandescent than to retail light. The half-peak beam angle is 36°: moderately narrow, for building a grid of points over a display, a worktop or a seating area, not for lighting a room with one unit. Colour rendering of CRI 90 matters precisely because of that narrow angle – it decides whether the object lit keeps its colour. Distribution is symmetrical, emission direct, photobiological risk group 1. Rated life 50,000 hours.

Installation figures

Supply 200–240 V AC 50/60 Hz, protection class I (earth conductor required), IP20 – dry interiors only. Two numbers absent from domestic luminaire copy and decisive in a specification: inrush current 2.75 A for 190 µs, and a maximum of 94 luminaires on one circuit protected by a B16A or C16A breaker. Ambient temperature range: −20 to +50 °C. The LED module carries reference 1411536.

The NUMINOS system

NUMINOS is SLV's modular system of downlights and spotlights in several sizes and mounting versions – recessed, surface, pendant and track – sharing one appearance and one optical family. In practice that means recessed fittings can run where there is a suspended ceiling and surface ones where there is not, with a consistent lighting effect throughout.
