Product descriptionQuintessence square sets standards in visual comfort, efficiency and light quality for recessed luminaires. The range comprises downlights, lens wallwashers and directional spotlights. Quintessence downlights and lens wallwashers offer effective glare control and high uniformity; the 90° beam angle combined with a 40° cut-off enables wide luminaire spacing for efficient general lighting.
Special features- High visual comfort: ERCO Darklight reflector provides strong glare control with an optimized light output ratio.
- Office-suitable: designed for low glare; UGR values support normative lighting design when applied to the actual luminaire layout.
- Mounting options: standard covered recessed detail; flush mounting frames available as accessories.
Individualisation / Variants (examples)- Reflector finishes: matt gold, matt silver or matt champagne.
- Connection: 3- or 5-pole plug options (Wago or Wieland).
- Mounting frame colours: up to 10,000 colours available on request.
Product features in detail- ERCO Darklight reflector (Downlight): 40° cut-off; aluminium, anodised, satin matt.
- Wallwasher reflector: 80° cut-off; aluminium, anodised, satin matt.
- ERCO LED-module: high-power LEDs in 2700K, 3000K, 3500K or 4000K; directional optics with collimating lens in optical polymer.
- Diffuser / lens: optical polymer; options include diffuser lens, wide flood, extra wide flood or lens system for wallwash; directional luminaires use Spherolit lenses (narrow spot, spot, flood).
- Mounting frame: covered installation detail standard; fixing for ceiling thickness 1–30 mm; flush mounting frame available separately for 12.5–25 mm ceilings.
- Housing: die-cast aluminium heat sink; fixing frame polymer black; directional versions tilt 0°–20°, rotate 360°, lockable.
- Control gear: switchable, phase dimmable (trailing edge), DALI dimmable or Casambi Bluetooth.
Applications / System overview (highlights)- Downlights: wide rotationally symmetrical distribution for general lighting. Power range 12.1 W–32.4 W; luminous flux 1163 lm–4192 lm.
- Lens wallwashers: asymmetrical distribution for uniform wallwashing. Power range 8.1 W–24.3 W; luminous flux 776 lm–3144 lm.
- Directional luminaires: narrow to wide beams for accent lighting. Power range 2 W–24.3 W; luminous flux 194 lm–3144 lm.
- Luminaire spacing guidance: downlights spacing d ≤ 1.5 × height h; wallwasher offset a ≈ 1/3 × room height h and spacing d ≤ 1.3 × a for good longitudinal uniformity.
