Product Overview
FST-SP-KF-FH is a compact recessed COB LED downlight with a curved trim and deep optical chamber. Four sizes are available from 5W to 12W for Ø45mm, Ø55mm, Ø65mm and Ø75mm ceiling cut-outs. Beam angles of 15°, 38° and 45° can be selected for focused accent lighting or wider general illumination. The aluminum housing supports heat dissipation, while CRI ≥ 92 and 3000K, 3500K or 4000K options make the series suitable for residential, hotel, retail and commercial projects.
Choose from 15°, 38° or 45° beam angles to suit accent lighting, general lighting or wider area illumination. Standard color temperatures are 3000K, 3500K and 4000K, with CRI ≥ 92 for accurate color rendering.
Size / Cut-out / Power Options
Available in four product sizes, ceiling cut-out sizes and wattage options. Confirm the cut-out size and available installation depth before sample or bulk order.
| Product Size | Cut-out Size | Power |
|---|---|---|
| Ø52 × H62mm | Ø45mm | 5W |
| Ø62 × H75mm | Ø55mm | 7W |
| Ø72 × H80mm | Ø65mm | 10W |
| Ø82 × H77mm | Ø75mm | 12W |
Where This Curved-Trim Recessed Downlight Is Best Used
FST-SP-KF-FH is designed for homes, villas, hotel rooms, offices, restaurants, retail stores and compact commercial interiors that require a clean recessed appearance and controlled light distribution. The small 5W and 7W sizes work well in compact ceiling areas, while the 10W and 12W options provide more output for larger rooms or higher lighting requirements.
The curved trim softens the visible transition between the ceiling and the optical opening. A deep optical chamber helps keep the light source less exposed from normal viewing angles, making the fixture suitable for spaces where visual comfort and a neat ceiling finish are important.
How to Select the Size, Power and Beam Angle
| Project condition | Recommended option |
|---|---|
| Small cabinet, corridor or compact ceiling zone | Start with the 5W model, Ø52 × H62mm, for a Ø45mm cut-out. |
| Bedroom, hotel room or small residential area | Review the 7W model, Ø62 × H75mm, for a Ø55mm cut-out. |
| Living area, office or medium commercial space | Compare the 10W model, Ø72 × H80mm, for a Ø65mm cut-out. |
| Retail display or higher output requirement | Review the 12W model, Ø82 × H77mm, for a Ø75mm cut-out. |
| Focused accent lighting | Select 15° when the target area is small and the installation distance has been confirmed. |
| General lighting or wider coverage | Choose 38° or 45° according to ceiling height, fixture spacing and the required illuminated area. |
The same wattage can produce a different result when the beam angle, ceiling height and fixture spacing change. For project selection, confirm the floor plan, ceiling height, target area and required lighting effect before ordering.

Frequently Asked Questions
Which wattage should I choose?
Choose the wattage together with the ceiling height, fixture spacing and target illuminance. A higher wattage is not always necessary when the fixtures are installed closer together or the target area is small.
Which beam angle is suitable for general lighting?
38° or 45° provides wider coverage for general lighting. Use 15° when a smaller object or display area needs more focused light.
Can I replace an existing recessed downlight with this model?
Measure the existing ceiling cut-out and available installation depth first. Select the model only when the product diameter, cut-out size, body height and driver space are suitable.
Can the reflector and driver be customized?
Matte white or matte black reflector options are available. Driver brand, dimming or smart-control requirements can be evaluated according to the project quantity and technical specification.
Can I order a sample before bulk production?
Yes. A sample can be used to confirm the beam angle, color temperature, reflector finish, cut-out fit and lighting effect before a bulk order.
