Northern Lights: this translates into extreme seasonal differences in the lengths of days and nights, particularly hard, dark winters and long periods of dusk and dawn. The architecture responds to these conditions with sophisticated lighting which plays a prominent roll in the overall concept. On the metal-clad roof surfaces at night, Beamer projectors conjure up a lively, emotive pattern of light, whose form is reminiscent of the Northern Lights (Aurora Borealis). Projector mounting is facilitated by robust system accessories with masts and cantilever arms in matching design.
