Surface mounted downlight ATRIUM DOPPELFOKUS

LEDcylindricalfor public building

Overview
The ERCO Atrium double focus are surface-mounted downlights designed for precise, high‑lumen illumination from large heights in foyers, theatres, lecture halls and other high rooms. The range focuses light accurately to avoid spill and offers optical and housing options to maximise visual comfort and lumen output.

Special features

• High visual comfort through specialised housing geometry and quality optical components
• Large lumen packages to achieve high illuminances while maintaining glare control
• Optimised for installation in rooms with high ceilings to prevent unwanted spill light

Product description

• Cylindrical surface-mounted housing with a light‑tight ventilation gap as a design element
• Narrow downlight distributions (precise downlight projections) optimised for illumination from large heights; available beam shapes: Flood and Wide flood
• Available within the Atrium family as surface-mounted downlights (this variant), pendants and recessed versions; pendant variants can include an optional indirect uplight
• Optional anti‑glare cone in black or silver to reduce visual glare
• In‑house developed control gear ensures uniform behaviour of luminaire groups and supports dimming via common control options including DALI
