Specification Overview

ADL C Deep enhances visual comfort with its deeply recessed light source and advanced low-glare optical geometry, making it perfect for environments where a refined, discreet ceiling appearance is essential.

The deep optical chamber creates soft cut-off angles (UGR < 13) and minimises direct lamp visibility, supporting luxury commercial, hospitality, and residential spaces. A die-cast aluminum heat sink ensures passive thermal dissipation and long service life (L90B10 > 60,000h). Emergency lighting capable with the addition of an optional 3-hour battery pack.
