Triedro recalls the stage lamps of the photo sets. The lampshade, containing an silver dome bulb with an E27 attack, is in shaped metal and folded in three parts, so as to reflect the light without dazzling. A large flexibility of movement is guaranteed by the double load -bearing joint, which allows the rotation and inclination of the light source in any position.
