The POSE Task is a high output task lamp based on conical forms that playfully explores the world of optical physics, through the world of flat lenses -often seen in lighthouses. With anthropomorphic charm, POSE manipulates light into focused, magnified beams with striking effect. A strong silhouette and touch of humour define its personality, while precise adjustability and high light output ensures adaptability and functionality for any space— domestic or contract. Balancing functionality with minimal design, POSE radiates light and individuality with equal brilliance
