Round Thin Recessed SMD LED Downlight Model SL-CL3E from Synno Lighting

Aluminum 20w 120mm Cutout Round LED Downlight

Detailed Product Description:

1. Product Overview: Compact Cutout, High Performance Output

The Round LED Downlight is a high-efficiency recessed LED lighting solution designed for projects where compact ceiling openings, powerful lumen output, and long-term reliability are all required simultaneously. With a precise 120mm cutout, this model is especially popular in modern residential, hospitality, retail, and office environments where ceiling space is limited but lighting quality cannot be compromised.

Unlike low-power compact downlights, this 18W version delivers strong, uniform illumination while maintaining a clean architectural appearance. It combines advanced LED optics, heavy-duty aluminum construction, and professional driver design, making it a preferred choice for contractors, developers, and distributors seeking performance consistency across large installations.

2. Precision 90mm Cutout Design for Architectural Consistency

Ceiling design is becoming increasingly minimalistic. This 90mm cutout downlight allows designers to maintain small, uniform ceiling openings without sacrificing brightness. It is ideal for:

• Hotels with dense lighting layouts

• Apartments with low ceiling voids

• Commercial offices with modular ceiling systems

• Retail shops requiring clean visual lines

The compact cutout ensures a refined and seamless ceiling finish, especially in high-end interiors.

3. High-Efficiency LED Module: Power Concentrated in Small Space

Despite its small opening size, the 20W LED module is engineered to deliver up to 1600–1800 lumens, thanks to high-efficiency LED chips and optimized thermal pathways.

Key benefits:

• High lumen density per cutout area

• Reduced fixture quantity per project

• Energy savings compared to traditional lighting

• Uniform illumination without hotspots

This makes the downlight suitable for primary lighting, not just auxiliary or decorative use.

4. Die-Cast Aluminum Housing: Thermal Stability & Longevity

The entire fixture body is made from thick die-cast aluminum, providing superior heat dissipation and structural stability.

Why aluminum matters:

• Keeps LED junction temperature low

• Prevents lumen degradation over time

• Improves driver reliability

• Extends overall fixture lifespan

The aluminum surface is finished with electrostatic powder coating, available in white, black, or custom colors, ensuring corrosion resistance and consistent appearance for years.

5. Advanced Optical System for Visual Comfort

Lighting quality is not just about brightness; it’s about comfort. This product uses a multi-layer optical system to ensure smooth light output and minimal glare.

Optical components:

• High-transmittance diffuser

• Anti-glare recessed lens design

• Optional honeycomb louver

• Deep LED placement

UGR < 19 is achievable, making it suitable for offices, schools, and commercial spaces where visual comfort is critical.

6. Color Temperature & CRI Options for Project Customization

The downlight is available in multiple color temperatures:

• 2700K – Warm white (residential, hospitality)

• 3000K – Soft white (hotel rooms, restaurants)

• 4000K – Neutral white (offices, classrooms)

• 5000K – Cool white (commercial spaces)

Color Rendering Index:

• CRI >80 standard

• CRI >90 optional for premium projects

High CRI ensures that furniture, walls, and merchandise appear natural and vibrant under the light.

7. Long Lifespan & Maintenance-Free Operation

With a rated lifespan of ≥50,000 hours, the downlight significantly reduces maintenance frequency, especially important for:

• Hotels

• Shopping malls

• Office buildings

• Public facilities
