Quintessence round Recessed luminaires

The system solution for excellent visual comfort

Large luminaire spacing, high uniformity and excellent visual comfort

Quintessence recessed luminaires, available in round and square versions, set new standards in their category: The high-performance range, consisting of downlights, lens wallwashers and directional luminaires, meets superior standards of visual comfort and efficiency whilst delivering optimal light quality for a multitude of visual tasks.
The new optical systems of the downlights and lens wallwashers produce superb uniformity

whilst ensuring excellent glare control.
With an emission angle of 90° and a 40° cut-off, Quintessence downlights meet the challenges of illuminating large areas masterfully – offering uniform and efficient ambient lighting with large luminaire spacing and high cylindrical illuminances.
ERCO control gear guarantees consistent dimming characteristics of these lighting tools and can be dimmed down to 1%. The shallow recess

depth allows Quintessence units to be used flexibly in different spatial situations.
