The design of the SETA pendant light with a power of 9 W is inspired by Asian paper lanterns. However, the shade is made not of paper, but of mulberry silk fiber—a unique natural material that creates a cozy atmosphere, producing soft light reflections.
The light fixture supports dimming functionality (when using the appropriate driver): brightness smoothly changes, setting the desired mood. The color rendering index CRI>97 guarantees the most natural colors of surrounding objects.
Included are two mounting cups: one for surface mounting, the other for recessed mounting.
