SYNNO SL-CL3A SMD Recessed LED Downlight -- Uniform 60 Degree Wide Beam, Deep Cup Anti-Glare Design

The SYNNO SL-CL3A is a fixed SMD recessed LED downlight built for general indoor illumination where broad, uniform light coverage matters most. Unlike adjustable gimbal spotlights, this white color aluminum LED downlight uses a fixed deep-cup reflector with a 60-degree wide beam angle and matte white interior baffle to deliver even, glare-free light across residential and commercial spaces. The SMD (Surface-Mounted Device) LED array provides reliable, energy-efficient output with CRI 80/90 color rendering. Available in 5 power options from 10W to 35W across five cutout sizes (75-155mm), including a 35W commercial LED ceiling downlight for large-area coverage, every unit is manufactured under SYNNO's ISO 9001:2015 certified facility in Jiangmen, China, backed by 15+ years of OEM/ODM expertise.

» Key Features

1. 60 Degree Wide Beam -- Wide Illumination, Even Light Distribution

The SL-CL3A is purpose-designed for uniform area lighting. Its 60-degree beam angle spreads light broadly across floors, walls, and work surfaces -- ideal for open-plan living rooms, hotel corridors, retail floors, and commercial ceilings where even coverage takes priority over focused accent. The wide beam reduces the total number of fixtures needed per square meter compared to narrow-beam alternatives, lowering both hardware and installation costs for large-scale projects.

2. Deep Cup Anti-Glare -- Soft, Glare-Free Light

The deep-recessed cup design physically blocks the LED source from direct line-of-sight. The matte white interior baffle absorbs and diffuses stray light before it exits the fixture, eliminating the harsh glare common in shallow downlights. The result is a soft, comfortable illumination that reduces eye strain during extended periods -- a critical advantage for residential bedrooms, hotel guest rooms, and office spaces where visual comfort is non-negotiable.

3. SMD LED Source -- Reliable Quality, Consistent Output

SMD (Surface-Mounted Device) LED technology mounts individual LED chips directly onto a printed circuit board, providing proven reliability and consistent lumen output across thousands of operating hours. The SL-CL3A's SMD array delivers 100-120lm/W at the chip level (70lm/W whole-fixture), offering an excellent balance of performance, cost-efficiency, and long-term dependability for volume-driven commercial and residential projects.

4. Five Color Temperatures + Customizable Lamp Beads

Lamp beads are customizable across seven tier-one manufacturers: Bridgelux, Citizen, Cree, Epistar, Luminus, Osram, and Philips -- every SMD module is traceable with manufacturer datasheets available upon request.

5. Flicker-Free Driver -- Eye-Caring Performance

A constant-current driver eliminates perceptible flicker, ensuring comfortable extended viewing and clean, band-free images when photographed. Essential for hotel guest rooms, residential bedrooms, and commercial spaces where lighting quality directly impacts occupant comfort and satisfaction.

6. Narrow Rim + Spring Clip Mounting -- Flexible, Fast Installation

The narrow rim design sits nearly flush with the ceiling, minimizing visual bulk. Two red-tipped spring-loaded metal clips on opposite sides of the housing secure the fixture firmly into the cutout. Installation takes seconds: cut the hole, connect wiring via the integrated driver, push the fixture up, and the springs lock it in place. Compatible with standard ceiling board thicknesses.

» Application Scenarios

Residential -- Living Rooms, Bedrooms & Kitchens

The 60-degree wide beam covers large living areas with fewer fixtures. The deep cup anti-glare design ensures comfortable lighting for bedrooms where occupants spend extended hours. CCT options from warm 2700K to neutral 4000K suit every room mood.

Commercial -- Offices, Corridors & Retail Floors

The SL-CL3A 35W variant is purpose-built as a commercial LED ceiling downlight for large-area coverage in open-plan offices, hotel corridors, and retail floors. Uniform 60-degree distribution eliminates dark spots between fixtures, creating a professional, evenly-lit environment. Rapid heat dissipation ensures reliable operation during extended daily run times.

Hospitality -- Hotel Guest Rooms & Common Areas

SMD reliability + flicker-free driver + deep cup comfort make the SL-CL3A ideal for hotel guest rooms where maintenance costs and guest satisfaction are equally critical. Narrow rim design integrates cleanly into any ceiling type.

» FAQ

Q: What ceiling thickness does the spring-clip mounting support?
A: Standard clips accommodate 5-25mm ceiling board thickness. Custom clips for thicker materials available on request.

Q: Is the beam angle adjustable?
A: No. The SL-CL3A is a fixed 60-degree wide beam downlight. For adjustable directional lighting, consider the SL-CL30A gimbal series or SL-CL30G surface-mounted spotlight.

Q: Can the SL-CL3A be used outdoors or in bathrooms?
A: The SL-CL3A is rated IP20 for dry indoor use only. For bathrooms or outdoor covered areas, consult our IP44/IP65-rated downlight series.

Q: Are IES files available for Dialux/Relux?
A: Yes, for all 5 power variants. Complimentary Dialux simulation also available.
