Premium Cost-Effectiveness Ultra-Slim Downlight for Architectural Lighting
Engineering Value Proposition: Optimized lumen output per watt (≥80 lm/W) combined with minimized installation depth (22mm profile) enables rapid deployment in shallow-plenum retrofit scenarios prevalent in European Grade-B commercial renovations.
Category Compliance: Classified under IEC 60598-2 "Recessed Luminaires" with IP20 indoor dry-location rating, explicitly excluding humid/damp environments (bathrooms/kitchens).
Technical Execution: Horizontal ±30° tilt range via captive torsion spring + dual-axis gimbal.
Certification Reference: Beam stability validated per EN 60598-2-2 vibration test (2Hz-50Hz @ 0.35mm amplitude).
Application Impact: Eliminates complex ceiling adjustments when illuminating dynamic retail displays (e.g., rotating mannequin platforms).
Spring Specifications: Cold-forged SUS304 stainless steel snap springs (0.8mm thickness) with 12kg retention force - compliant with AS/NZS 60598.2.2 tension requirements.
Finishing System: Powder-coating customization against RAL Classic K7 color deck (150+ options), excluding textured/gloss finishes due to conductivity risks.
Supply Chain Note: Minimum 500-unit MOQ per custom color batch (lead time: 25 days).
COB Selection Logic: Mid-power 3030 LED array (Lumileds LUXEON 3030 HE) with 80CRI binning - achieving optimum balance between flux density ($/klm) and thermal derating.
Driver Specification: Non-dimmable 0.5PF constant-current driver achieving 85% efficiency at 220Vac, housed in isolated IP20 compartment.
