The FLOS Chasen S2 Pendant Light in white is a suspension lamp built around a chemically photo-etched stainless-steel body, protected by a liquid-paint finish and paired with a borosilicate glass diffuser that spreads the light evenly across a room. FLOS engineers the fixture with a mechanical movement that opens and closes a set of louvres, physically reshaping the pendant and letting the light emission shift from a tighter downward pool to a broader, softer wash. This adjustability is what sets the Chasen S2 apart from static pendants: the same fixture can suit a quiet reading corner one evening and a fuller dining glow the next. Underneath the sculptural white shell, the construction follows FLOS's usual attention to build quality, with a die-cast aluminium base, a ceiling rose in 30% fibreglass-reinforced polyamide, and a pressed, galvanised steel ceiling fixture for secure mounting. A steel suspension cable carries the fixture, keeping the visual weight on the louvred body rather than on visible hardware. Because of its adjustable form and diffused output, the Chasen S2 works well over dining tables, kitchen islands and living room seating areas where the mood of the light needs to change through the day. It is supplied here as a genuine FLOS product, part of the Chasen family of pendant luminaires. If you are weighing this fixture against other pendants for a specific room or ceiling height, our lighting design team is glad to talk through the louvre mechanism and placement options with you.
