Commercial Recessed LED Downlights: COB vs SMD, Beam Angle Selection & Dimming Drivers

# Commercial Recessed LED Downlights: COB vs. SMD Optics, Beam Angles, and Deep Anti-Glare Design

Recessed downlights are the primary workhorse of commercial architectural lighting, requiring strict glare cut-off angles and high color fidelity.

## 1. COB (Chip-on-Board) vs. SMD Array Downlights
- **COB LEDs (Single Point Source)**: Crisp, clean shadows with high punch and defined beam angles (15°, 24°, 36°).
- **Deep-Set Dark Light Reflectors**: Anti-glare optics protect visual comfort in hospitality and office applications.
