Modern lighting design requires both aesthetic appeal and reliable performance. Therefore, the Modern Surface Mounted COB LED Downlight provides a practical solution for architects, designers, and contractors who want elegant ceiling lighting without complicated installation requirements.
Unlike traditional recessed downlights, this surface mounted fixture installs directly onto the ceiling surface. As a result, installers do not need large ceiling cutouts or deep mounting cavities. This feature makes the fixture especially useful for concrete ceilings, renovation projects, or spaces where recessed lighting cannot be installed.
Additionally, the refined color combinations elevate the visual style of modern interiors. Customers can choose between sand black with matte rose gold accents or sand white with a transparent finish. Consequently, the fixture blends naturally with contemporary commercial spaces, boutique stores, hospitality environments, and stylish residential interiors.
Because the product belongs to the professional LED Lighting collection from OKELI, it delivers consistent performance while supporting modern energy-efficient lighting strategies.





Lighting performance strongly depends on the quality of the LED source. For this reason, the downlight integrates Sanan COB LED chips, which are widely known for stable illumination and reliable efficiency.
COB technology concentrates multiple LED chips into a single light-emitting surface. Therefore, the fixture produces smooth and uniform lighting with minimal glare. In addition, the luminous efficiency reaches up to 83LM/W depending on the model, allowing the light to deliver bright illumination while maintaining energy efficiency.
The color rendering index reaches CRI 80, which ensures accurate color representation in interior environments. Consequently, products, décor elements, and architectural details appear more natural and visually appealing under this lighting.
Furthermore, three color temperature options provide flexibility for different lighting atmospheres.
3000K produces warm lighting suitable for homes, hotels, and restaurants.
4000K creates neutral illumination ideal for offices and retail stores.
6000K generates crisp white lighting that supports task-oriented environments.
Because of these options, lighting designers can easily adapt the fixture to different interior applications.





Lighting design often requires different beam spreads depending on the layout of the space. Therefore, this surface mounted LED downlight offers four beam angle options: 15°, 24°, 36°, and 55°.
Narrow beam angles such as 15° and 24° work perfectly for accent lighting and product displays. Meanwhile, 36° provides balanced illumination suitable for most general lighting scenarios. The wide 55° beam angle creates broader coverage for ambient lighting across ceilings and walls.
This versatility allows designers to highlight architectural features while maintaining comfortable illumination levels throughout the space.
Moreover, the fixture integrates easily into larger Indoor Lightingsystems. Multiple fixtures can be arranged to achieve consistent lighting across commercial environments such as showrooms, galleries, and retail stores.
Lighting durability depends heavily on thermal management and structural quality. Therefore, the fixture uses high-quality aluminum housing that ensures both strength and efficient heat dissipation.
Aluminum naturally transfers heat away from the LED chip, which helps maintain stable operating temperatures. Consequently, the internal components remain protected while the LED lifespan increases significantly.
In addition, the integrated body design improves structural stability and enhances the overall appearance of the fixture. Because the housing remains compact yet robust, the downlight maintains long-term performance even in demanding commercial environments.
Although the product is primarily designed for indoor installations, it can complement architectural environments that combine interior and exterior lighting solutions. For example, designers may integrate it with professional Outdoor Lighting systems to create consistent lighting transitions between indoor and semi-outdoor areas.


Different spaces require different illumination levels. Therefore, this product series includes three power configurations to accommodate diverse project requirements.
Model LD-11-35301 provides 15W power output with luminous efficiency of 83LM/W. The fixture measures Ø74 × H100mm, making it suitable for compact ceiling installations where space efficiency matters.
Model LD-11-35302 offers higher output at 25W with luminous efficiency of 80LM/W. The fixture size is Ø94 × H110mm, which provides stronger illumination for medium-sized interior spaces.
Model LD-11-35303 delivers powerful lighting at 35W with efficiency reaching 82LM/W. With dimensions of Ø114 × H140mm, this version suits larger commercial environments that require brighter lighting coverage.
Because each model maintains consistent optical performance, designers can mix different wattages within the same project while preserving uniform visual aesthetics.
Installation efficiency plays a key role in modern construction projects. Therefore, this surface mounted LED downlight features a straightforward mounting design that simplifies the installation process.
Electricians can attach the fixture directly to the ceiling using standard mounting hardware. Consequently, installation becomes faster and more convenient compared with traditional recessed lighting systems.
The standardized Ø20mm opening requirement across all models further simplifies planning for large-scale lighting installations.
Because contractors can complete installations quickly, project timelines remain efficient while labor costs remain manageable.
Versatility remains one of the strongest advantages of this surface mounted LED downlight. The fixture adapts easily to a wide variety of interior environments.
Retail stores benefit from focused beam angles that highlight merchandise displays. Restaurants and cafés use warm lighting tones to create inviting atmospheres. Offices and commercial buildings appreciate the clean design and consistent illumination.
Meanwhile, residential interiors such as living rooms, corridors, and kitchens gain elegant ceiling lighting that enhances modern décor.
Because the fixture combines efficiency, durability, and visual sophistication, it becomes a reliable choice for contemporary architectural lighting design.
Reliable lighting forms the foundation of successful interior design. Therefore, choosing high-quality fixtures becomes essential for both residential and commercial projects.
The Modern Surface Mounted COB LED Downlight delivers strong illumination, stylish design, and dependable performance. Thanks to Sanan LED technology, durable aluminum construction, and flexible beam angles, the fixture supports diverse lighting applications with ease.
When integrated into a professional LED Lighting strategy and a comprehensive Indoor Lighting system, this downlight provides a refined and efficient lighting solution for modern architectural environments.
