Filamento Horizontal Single Suspension by Astep

A sculptural bar of light across the room: the Filamento Horizontal Suspension lines four lamps inside borosilicate glass for a clean, architectural line over a table or counter.

Designed by Mayice Studio for Astep, it is offered with less glass or more glass, and measures 1,307 mm (51.5 in) end to end.

“Filamento sprung from the observation of how light passes through glass.” — Mayice Studio

Why we carry it

We have been curating design-led pieces since 2009, and Filamento is the kind of lighting we look for: architectural, quiet and built around one honest idea. It comes from Astep, the house founded by Alessandro Sarfatti, whose family helped define modern Italian lighting.

Buy once: durability and care

Keep the fixture indoors and dry. Disconnect power before cleaning, then wipe the glass and aluminum with a soft, dry or lightly damp cloth and dry thoroughly. Bulbs are not included, so use the lamp type and wattage listed above.
