A deep recessed downlight is a lighting fixture designed to be installed within a ceiling, where the light source is positioned deeper inside the housing. This design minimizes glare and creates a focused, uniform light distribution, making it ideal for residential, commercial, and hospitality applications.

2. Key Specifications

Housing & Construction:

• Material: Aluminum die-cast or sheet metal for durability and efficient heat dissipation.
• Finish: Powder-coated, anodized, or painted finish in colors like white, black, or metallic.
• Trim Options: Available with flanged or trimless designs for aesthetic versatility.
• Recess Depth: Generally 75–120 mm (or more) for optimal glare control.

Lighting Source:

• LED Chip Type: COB (Chip-on-Board) or SMD (Surface-Mounted Diodes).
• Color Temperature (CCT): Typically available in 2700K, 3000K, 4000K, and 5000K options.
