The Kuulto lamp by Secto Design is constructed of acrylic glass, white-painted steel, and form-pressed birch slats – the latter playing the leading role in the design, especially as it is not very commonly used in ceiling lamps. Designed by Seppo Koho, the Kuulto lamp can be also used on the wall either independently or in larger custom compositions. The light is dimmable to easily adjust the atmosphere of the space.
