Filamento Horizontal Double Suspension by Astep

Light at architectural scale: the Filamento Horizontal Double stretches over two meters of borosilicate glass and aluminum, with seven lamps in a single clean line.

Designed by Mayice Studio for Astep, it comes in three glass combinations: less and less, more and less, or more and more.

“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.
