Brand: SLV

It turns a round pool of light into an oval one That is the whole function of this part, and it is meant literally. A downlight with no accessory throws a round pool — that is the symmetry of its optics. This diffuser, dropped into a NUMINOS fitting, stretches the light cone along one axis, so the pool on the floor or the wall becomes an ellipse. Rotating the insert in its seat chooses which way the ellipse is stretched. When it matters Wherever the surface being lit is not itself round. Over a long kitchen run or a reception desk, a row of round pools leaves dark pinches between them; oval pools overlap along the counter and give continuous light from the same number of fittings. The same applies to a narrow corridor, a shelving unit or a landscape-format picture — the ellipse takes in the whole object, whereas the circle lights the centre and loses the edges. Clear PMMA, near-lossless The insert is made of clear PMMA (polymethyl methacrylate, that is acrylic glass) and works as a lens rather than a screen — it does not scatter the light into a milky wash, it reshapes the beam. Output loss therefore stays small and the colour temperature is unchanged. The element weighs 4 grams and measures 4.75 cm across by 2 mm thick. A system part, not a standalone product NUMINOS is a modular system: the fittings are chosen separately by efficiency class, wattage, colour temperature and beam angle, while optical inserts like this one change the characteristic of a fitting already installed. The practical consequence is that the light distribution can be changed after installation, without swapping the downlight and without touching the ceiling. The diffuser itself does not light and does not work without a NUMINOS fitting.
