Louvre light with aluminium parabolic mirror louvre & micro perforation This sturdy louvre light is universally suitable for ceilings with visible or concealed mounting rails as well as cut-out installation openings. The first-class quality of this louvre light is ensured by the exclusive use of high-quality brand name ballasts from Vossloh. The electronic ballast (EB) is already integrated into the light. The light is specially designed for visual display unit workstations. The high-gloss polished louvre consists of ultra-pure aluminium & has a micro perforation (slight perforation on the plates between the louvres) for optical reasons.
