Project: Boutique Hotel Façade Lighting

Model: SYA-807-60 (1 m), 48 W, 30° beam, 4000 K neutral white

Electrical: DC24 V low-voltage system; IP66 waterproof connectors; 6 kV surge protection

Optics: Precision linear wall-wash; SDCM ≤ 3; tempered glass lens for uniform distribution

Installation: Continuous rows at 1.0 m spacing, mounting height 3.2–3.5 m; bracket setback 50 mm from wall; tilt 12–15° for even graze; cable hidden in back channel

Control: On-Off / DALI grouped zones (base/mid/cornice) with evening dimming schedule (100%→60%→30%)

Acceptance: Vertical illuminance Eᵥ ≥ 80 lx (avg) on façade; uniformity Emin/Ē ≥ 0.4; edge fall-off ≤ 15% within 0.5 m; glare limited at public viewpoints (subjective “low”)

Outcome: Smooth, glare-controlled façade wash that reveals texture and rhythm; reduced energy vs. legacy fixtures; simple maintenance via accessible low-voltage runs and modular 1 m bars
