RZB Recessed lights
rzb downlights portfolio for professional fit‑outs
RZB downlight families are built for repeatable optics, robust mechanics, and drivers that behave on modern controls. Designers can keep one visual language from reception to back‑of‑house by swapping beams, trims, and outputs without redrawing ceilings or retraining crews.
rzb recessed downlights product range and series overview
Fixed round/square bodies for offices, corridors, and healthcare. Common lumen packages 600–4,000 lm with efficacies 110–150 lm/W. Beam sets typically 15° / 24° / 36° / 60° with low‑glare reflectors or micro‑prism lenses.
Wall‑wash and asymmetric optics for perimeter shelves and feature walls. Uniform vertical illuminance with minimal spill onto ceilings.
Shallow can variants for tight voids; remote‑driver options reduce height. Cut‑out sizes cover mainstream ranges (≈68–150 mm).
Emergency and sensor‑ready options integrate test switches, remote batteries, or presence/daylight heads on selected series.
rzb led downlight fixtures technical specifications and standards
- Optical performance: office‑grade options target UGR < 19; reflector systems control high‑angle brightness. SDCM ≤ 3 keeps batches visually consistent.
- Color: CCT 2700 / 3000 / 3500 / 4000 K as standard; CRI ≥ 80 with CRI ≥ 90 options (high R9 for retail and healthcare).
- Electrical/driver: universal input 100–240 V AC; PF ≥ 0.90; THD < 15% on DALI drivers. Dimming choices DALI‑2, 1–10 V, and trailing‑edge on selected loads. Surge immunity typically 2–4 kV (L‑PE); inrush documented for RCBO/relay sizing.
- Lifetime: LED engines qualified to LM‑80 with TM‑21 projections; families commonly L80 B10 ≥ 50,000–70,000 h at ta 25–35 °C.
- Protection: from‑below ingress IP20/IP40; sealed faces up to IP44/IP54 for bathrooms; selected outdoor canopies IP65. Impact classes IK07–IK08 where specified.
- Thermal: heat paths sized to keep Tc within limits; ambient bands typically −20…+40 °C (check data for sealed variants).
- Standards: construction/safety IEC/EN 60598‑1 and ‑2‑2 (recessed); control gear IEC/EN 61347‑2‑13; EMC EN 61000 / EN 55015 / EN 61547; photobiological EN 62471.
Installer note: maintain insulation clearances around recessed cans; use fire hoods where the ceiling rating demands it and only with trims approved for the kit
rzb ceiling downlights applications and compatibility
- Office and education: low‑UGR fixed optics for compliant workplane illuminance; 4000 K across open offices, 3000 K in collaboration zones.
- Retail and hospitality: tighter beams and warmer CCTs drive accent; CRI 90 with strong R9 lifts food and textiles.
- Healthcare and corridors: sealed faces for wipe‑down; asymmetric wall‑washers support wayfinding without glare.
Ceiling accessories—spring clips, retrofit rings, and alignment plates—match series geometry, so crews can maintain a consistent reveal line across rooms.
rzb trimless downlights integration with profiles and finishes
Trimless plaster‑in frames create continuous ceiling lines. Mesh‑edge rings embed before finishing; luminaires click into the carrier after sanding/painting. Coordinate with cove profiles and linear lines to keep joint geometry coherent. Keep driver access via service apertures or adjacent panels.
Where ceilings are exposed concrete or metal, use minimal‑bezel trims instead; the optical sets remain the same for consistent photometry.
rzb adjustable downlights product variants and aiming
Gimbal or tilt‑snoot bodies deliver ±20…35° tilt (model dependent) with lockable friction. Rotational aiming allows cross‑lighting of displays without spill. For galleries, specify low‑iridescence reflectors and verify color stability (SDCM) across dimming.
For high ceilings, consider higher‑output engines or narrow beams to hold target lux without over‑populating the grid.
Integration with other RZB systems and controls
Downlights share drivers and control logic with RZB panels and linear systems. Use DALI‑2 for scenes and monitoring; pair with presence/daylight sensors in open offices. In retail, combine adjustable accents with linear trunking for base light—one CCT/CRI policy keeps materials consistent.
Electrical practice: route SELV control away from mains in segregated duct; bond metal trims to PE where required; specify 2–4 kV surge headroom in buildings with frequent switching.
Selection criteria for B2B clients
- Task and beam — pick 15°/24°/36°/60° or wall‑wash to meet lux and uniformity; validate UGR for desk areas.
- Lumen package and efficacy — align to mounting height and spacing; aim for ≥120 lm/W where energy targets are strict.
- Color policy — lock CCT/CRI and SDCM ≤ 3 across the estate; keep CRI 90 for merchandising and clinical areas.
- Ingress & hygiene — IP44/IP54 from below in bathrooms; IP65 where jets or canopies apply; select wipeable trims in food/healthcare.
- Controls & emergency — unify on DALI‑2 where scenes/monitoring are needed; choose remote packs when voids are shallow.
- Ceiling & service — confirm cut‑out and void depth; pick trimless where plaster continuity is required; ensure driver access for MTTR.
Procurement typically standardizes one fixed low‑UGR family, one adjustable accent line, and a trimless kit for premium areas—spares and training stay simple.
Reliability operation and field data
Across recent office and retail programs, nuisance trips on RCBOs drop when drivers carry PF ≥ 0.90, THD < 15%, and 2–4 kV surge headroom. On IP44/IP54 versions, most leaks trace to uneven gasket seating after relamping—torque fasteners evenly and re‑seat seals. For adjustable optics, recheck aim locks during commissioning; temperature cycles can relax friction joints.
