- They usually provide a variety of color and brightness options and are easy to adjust to suit different lighting needs.

3. **Concealed card slot**:

- The card slot is usually equipped with a fixing clip or buckle to facilitate the installation and fixing of the light strip.

4. **Embedded ceiling aluminum profile**:
- This linear light is designed for embedded installation, that is, the lamp is installed inside the ceiling, with only the light-emitting part exposed.
- The aluminum profile provides structural support and an aesthetic appearance, while also helping to dissipate heat.

5. **Product Features**:
