Quintessence round. The system solution for excellent visual comfort

Large luminaire spacing, high uniformity and excellent visual comfort

Quintessence round

Excellent visual comfort

The darklight reflector combines maximum visual comfort with an optimum light output ratio.

Quintessence round

Different light distributions

Different light distributions let you adjust the light to suit the task at hand. The options range from very narrow accentuation through to wide beam floodlighting and even wallwashing.

Quintessence round

Suitable for workplaces

ERCO develops luminaires on the premise of efficient glare control and high visual comfort. UGR values are provided as an orientation around the current standards. The lighting design particularly for downlights, however, should be based on the individual arrangement of the luminaires in the room rather than on standard values.

Quintessence round

Covered or flush mounting possible

All recessed luminaires are supplied with a covered mounting detail. Flush mounting rings are available as accessories.

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.

General lighting

Ambient lighting produced by wide beam light distribution.

Downlights

Wide beam, rotationally symmetrical light distribution for general lighting.

  • LED
  • 12W - 32W
  • 1260lm - 4400lm
  • Extra wide flood

Downlights

For uniform ambient lighting with high visual comfort, the spacing (d) between two Quintessence downlights may be up to approximately 1.5 times the height (h) of the luminaire above the working plane.

Arrangement: d ≤ 1.5 x h

The wall offset should be half the luminaire spacing.

Arrangement: a = d / 2
