Where This IP44 Anti-Fog Downlight Is Best Used
FST-DL-LY01 is intended for bathrooms, kitchens, covered balconies and similar humid indoor ceiling areas. The wide-edge trim helps cover the ceiling opening, making it suitable for renovation projects where the existing cut-out edge needs coverage.
The curved reflector helps shield the light source from direct view. IP44 provides protection against solid objects larger than 1 mm and splashing water, but the fixture is not intended for immersion, direct water jets or exposed outdoor conditions.
How to Select the Size, Power and Beam Angle
| Project condition | Selection guidance |
|---|---|
| 75–80 mm cut-out or small humid indoor area | Review the 10W model, Ø90 × 45 mm. |
| 95–100 mm cut-out or medium bathroom and kitchen | Compare the 15W model according to room area and fixture quantity. |
| 120–125 mm cut-out or higher output requirement | Review the 20W model after checking ceiling height and layout. |
| 145–150 mm cut-out or larger area | Consider the 30W model only after confirming the required illumination and spacing. |
| More concentrated coverage | Select 36° when a narrower distribution is required. |
| Wider general illumination | Select 50° for broader coverage, subject to fixture spacing and ceiling height. |
The trim size, body size and cut-out must be checked separately. Wattage should be selected together with room dimensions, ceiling height, fixture quantity and target illuminance.

- Required power, 36° or 50° beam, CCT and CRI
- Light source, driver and dimming requirement
- Input voltage and local project requirements
- Quantity, sample, packaging and delivery schedule
Frequently Asked Questions
Can it be installed in a bathroom?
It is designed for humid indoor areas, but the bathroom installation zone and local electrical requirements must be checked before selection.
Can the wide trim cover an existing cut-out?
It may help cover the cut-out edge, but the existing opening, trim diameter and ceiling condition must be measured before ordering.
Which beam angle should I choose?
Choose 36° for more concentrated coverage and 50° for wider general lighting. Confirm the final option according to ceiling height and spacing.
Can I order a sample first?
Yes. A sample can be used to confirm cut-out fit, trim coverage, beam angle, CCT and selected control configuration.
