4.2 Función de zoom
The flashlight's head is zoomable, allowing adjustment between a focused spotlight and a wide floodlight beam.

- Sliding the head fóra (extending it) will narrow the beam into a spotlight for long-range illumination.
- Sliding the head in (retracting it) will widen the beam into a floodlight for illuminating a broad area.
