Quintessence round. The system solution for excellent visual comfort

Large luminaire spacing, high uniformity and excellent visual comfort

Special features of Quintessence round
View product description

Very high visual comfort

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

Suitable for office workstations

ERCO develops luminaires with the specifications of good glare control and high visual comfort. UGR values are used as support for purely norm-referenced lighting. With downlights though this should not be carried out using 'blanket' values, but should be implemented according to the individual arrangement of luminaires in the room.

Tunable white technology

Just as the colour temperature outdoors changes continuously during the day, the colour temperature of indirect lighting can be adjusted indoors to e.g. support lighting concepts for Human Centric Lighting.

Covered or flush mounting detail

As standard, all recessed luminaires have overlapping installation details. Flush mounting rings are available as accessories.

Quintessence sets standards in terms of visual comfort, efficiency and quality of light for recessed luminaires. The high-efficiency product family consists of downlights, lens wallwashers and directional spotlights in round and square designs. Characteristic of Quintessence downlights and lens wallwashers is their good glare control and high uniformity of illumination. The 90° beam angle and a 40° cut-off allow wide luminaire spacing between downlights and therefore high-quality, efficient ambient lighting. Tunable white technology also enables the colour temperature of the light to be modified. Human Centric Lighting concepts are thus supported, matched to the incident daylight.

Downlights

Wide beam, rotationally symmetrical light distribution for general lighting.

Downlights

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

Vertical illuminance for brightening and dividing the space.

Luminaire arrangement

Lens wallwashers

Asymmetrical light distribution for highly uniform wallwashing.

LED module
8W - 32W
790lm - 4400lm
Lens wallwashers

Lens wallwashers

For uniform vertical illuminance, the distance (a) of Quintessence lens wallwashers from the wall should be around one third of the room height (h).

Arrangement: a = 1/3 x h

For good longitudinal uniformity, the spacing (d) of Quintessence lens wallwashers may be up to 1.3 times the offset from the wall (a).

Arrangement: d ≤ 1.3 x a

The optimal wall offset and luminaire spacing for each product are indicated in the wallwasher tables in the catalogue and the product data sheets.

Emphasis of objects or architectural elements.

Luminaire arrangement

Directional luminaires

Very narrow to wide beam, rotationally symmetrical light distribution for accent lighting.

LED module
2W - 24W
200lm - 3300lm
Directional luminaires

Directional luminaires

Quintessence directional luminaires accentuate artwork, products and architectural details effectively. The ideal angle of tilt (α) for this is around 30°. The object is modelled without distorting the effect as a result of excessive shadowing. It also prevents shadows cast by the observer.

Arrangement: α = 30°
