Presented at this year's Milan design week, the concrete lamp features a rounded top, giving it a resemblance to a recently rereleased light by architect Le Corbusier.
The collection also includes tall and short versions of I-shaped and C-shaped pieces, which are available in a range of materials including oxidised bronze, concrete, cast iron and coated aluminium.
All the designs are intended for outdoor use, and include hidden LEDs covered by diffusing glass to allow for "optimal light distribution".
The structures of the I- and C-shaped lamps comprise a die-cast aluminium base, while the metal is extruded to form the heads.
"The aluminium alloy used for the die-casting has a low copper content to enhance resistance to corrosion," said Flos.
Van Duysen – whose previous projects include Alexander Wang's first European flagship store in London, and an Aesop store in Hamburg – was recently appointed the role of creative director at furniture brand Molteni&C Dada.
Van Duysen is Molteni's first creative director since the 1990s, when Italian designer Luca Meda held the role. Since then Carlo Molteni, the brand's president, has provided creative direction.
Flos' 2016 collection was presented at a space on Corso Monforte during this year's Milan design week, which took place from 12 to 17 April 2016.
Other lamps launched during Milan design week include a cordless light that generates its own electricity to additionally charge a smartphone, and a range of material-focussed pendants by British designer Tom Dixon.
