SLV NUMINOS DALI S 3-phase track spotlight white/black 7.8 W 4000 K 1004383

SLV NUMINOS DALI S 1004383 is an LED spotlight for a three-phase track, with a matt white body and a black surround at the optic. Its cylindrical head sits on a movable arm, allowing the beam to be directed independently of the track's route. This version combines a fixed 4000 K colour temperature with a 36° beam. The manufacturer specifies that replacing the LED source or control gear is a task for a professional, not a routine bulb change.

Direct light towards a specific surface

The 1100 lm output and 36° beam provide directional illumination rather than spreading light equally in every direction. Use that distribution to highlight merchandise in a shop, a picture in a living room or a detail on a corridor wall. With 350° horizontal rotation and 90° tilt, the head can be aimed towards the actual position of the object.

Its neutral white 4000 K light has no selectable colour-temperature settings. CRI 90 is relevant when comparing lighting for coloured objects. The result on a particular surface still depends on distance, aiming and other light sources, so the lumen figure alone does not establish the brightness of an entire room.

Match the track and control installation

This is a track-mounted fitting, not a recessed ceiling downlight. SLV specifies track installation on either a ceiling or a wall. Before choosing it, compare your track system and control wiring with the spotlight's requirements. The DALI version supports DALI-2 and Touch; that does not mean it works with every conventional wall dimmer.

The LED light source is fixed within the fitting. The current datasheet gives a nominal rating of 8 W, while its detailed description states 7.8 W. These are rounded presentations of the same rating, worth noting when comparing NUMINOS variants. Dimming adjusts brightness, not a choice between warm and cool white settings.

A compact cylinder with a contrasting front

The head diameter is 6.5 cm, with an overall length of 16.2 cm and height of 14.5 cm. Consider these dimensions alongside the track position and the space needed to tilt the head. The aluminium body, simple cylindrical outline and black front suit modern and minimalist interiors. This is a visible component of a technical lighting scheme rather than a decorative lampshade.
