The SLV NUMINOS XL 1004799 prismatic diffuser is a round, transparent PMMA optical insert. Its finely textured surface distinguishes it from a smooth cover. It is an accessory for the NUMINOS system, rather than a complete light fitting.
A softer edge to the beam
SLV states that this diffuser softens the boundary of the light cone while reducing glare. It changes the beam characteristics of a compatible fitting; it does not determine the fitting's wattage or colour temperature. Check those properties in the specification for the light itself. The application photograph illustrates the insert in a fitting, but the pictured fitting is not the item offered here.
XL size, 7.1 cm diameter
The insert measures 7.1 cm in diameter and 0.2 cm in height. Before ordering, compare the XL designation and article number 1004799 with the documentation for your chosen NUMINOS fitting. Matching diameter alone does not establish compatibility with an arbitrary fitting from another system. This transparent prismatic diffuser should also be distinguished from a frosted cover or a honeycomb louvre.
