15W/25W/40W Square Surface Mounted COB Downlight – DB-SLDL1
Square COB downlight with 15W, 25W, and 40W options, 20°/45° beams, and optional suspension kit. Designed for retail, hospitality, and commercial interiors.
Square COB Downlight for Surface or Suspended Installation
The DB-SLDL1 Series combines a clean square housing with a recessed round COB optic. It can be mounted directly to the ceiling or used with the optional one-metre suspension kit, allowing one product family to cover different ceiling conditions.
Key Project Benefits

How to Select the Configuration
Choose 15W for smaller rooms and lower ceilings, 25W for standard retail and hospitality areas, and 40W for larger spaces or higher mounting positions. Use the 20° beam for focused accent lighting and the 45° beam for wider coverage.
Surface-Mounted or Suspended?
Surface mounting keeps the fitting close to a solid ceiling. The optional one-metre suspension kit is suitable for high ceilings, exposed structures and spaces where the light source needs to be positioned lower. Suspension canopies are available in black or white.
Applications
Suitable for retail stores, restaurants, hotel public areas, reception desks, showrooms, galleries and commercial interiors.
