Where This Surface-Mounted Downlight Is Best Used
FST-DL-XW03 is designed for ceilings where a recessed cut-out is not available, practical or preferred. Typical applications include corridors, hotel rooms, retail areas, kitchens, bathrooms, covered balconies and commercial interiors that require direct surface installation.
An IP65 configuration is available. The exact installation environment, exposure to water and any project-specific certification or documentation requirements must be confirmed before ordering. Do not assume that an IP rating alone satisfies all local installation requirements.
How to Select the Size and Power
| Project condition | Selection guidance |
|---|---|
| Compact area or lower output requirement | Review the Φ80 × 90 mm, 15W model. |
| Small room, corridor or hotel area | Compare the Φ100 × 100 mm, 20W model according to fixture quantity. |
| Medium commercial or residential area | Review the 30W or 40W model after checking ceiling height and spacing. |
| Larger area or higher output requirement | Consider the 50W or 60W model only after confirming the lighting layout and target illuminance. |
| General lighting | The 55° beam provides broad coverage; spacing and mounting height should be checked to avoid uneven illumination. |
| Smart or building-control project | Confirm ON/OFF, Tuya, 0–10V or DALI before sample production. |
A higher wattage is not automatically the correct choice. Room dimensions, ceiling height, fixture spacing, surface reflectance and target illuminance should be considered together.
What to Confirm Before Ordering
- Surface-mounting position and available installation space
- Room dimensions, ceiling height and fixture quantity
- Required diameter, power, CCT, CRI and 55° beam suitability
- Whether the IP65 configuration is required
- Any certification or documentation required by the project
- Light source, driver, control method and input voltage
- Housing finish, quantity, sample, packaging and delivery schedule
Frequently Asked Questions
Does this model require a ceiling cut-out?
No. It is surface mounted and does not require a recessed opening, but the mounting surface and wiring position must be suitable.
Can it be used in a bathroom or covered balcony?
An IP65 configuration is available, but the exact installation zone, exposure to water and local electrical requirements must be checked.
Is certification included with every configuration?
Do not assume this. Any required certification or supporting document must be confirmed for the selected configuration before ordering.
Can I order a sample before bulk production?
Yes. A sample can be used to confirm the size, installation method, finish, CCT, CRI and control configuration.
