Quintessence double-focus downlights are designed with a relatively narrow light distribution for use in rooms with high ceilings. An optical system consisting of collimating and Spherolit lenses projects the light precisely onto the target surface, whilst the black anti-glare cone minimises the luminance when looking directly into the luminaire, making Quintessence double-focus downlights an incredibly efficient lighting solution in areas with high ceilings. Used in low rooms, the result is concentrated ambient lighting with efficient glare control. For the same degree of glare-free visual comfort in inclined ceilings, the recessed version can be tilted up to 30°. In auditoriums such as cinemas, theatres and concert halls, ERCO control gear guarantees consistent dimming characteristics of the luminaires, with continuous dimming down to 1%.

  • Double-focus downlights

General lighting

Ambient lighting produced by wide beam light distribution.

Double-focus downlights

Wide beam, rotationally symmetrical light distribution for general lighting. Good visual comfort in rooms with high ceilings.

  • LED
  • 6W - 32W
  • 630lm - 4140lm
  • Flood, Wide flood

Double-focus downlights

For uniform ambient lighting, the spacing (d) between two Quintessence double-focus downlights may be up to approximately half the height (h) of the luminaire above the working plane.

Arrangement: d = h / 2

Application: rooms with high ceilings, e.g. foyers or event spaces.

The wall offset should be half the luminaire spacing.

Arrangement: a = d / 2
