The device Luisa is using is called a "clamp light" (also known as a work light or utility light). Clamp lights are affordable and versatile lighting solutions that can be attached to various surfaces, such as the edge of a table, using an integrated clamp. The reflective shell helps to direct the light where it is needed. This is different from other lighting equipment like strobe lights, which are flash units, or tripods, which are stands used to support cameras or lights.
