Horn round recessed ceiling luminaire with recessed socket The Horn downlight is characterised by the recessed lampholder within the ceiling cut-out. This not only visually characterises the recessed luminaire, but also creates a softly defined light cone. Placed individually, Horn is suitable for area lighting; arranged in rows of several, the recessed luminaire also adequately illuminates a long corridor. The maximum ceiling thickness for recessing is 45 mm. - Clip springs included
