The Kawari Crane is the first in Brittain's Crane series to feature a curved glass element. The arc-shaped tube wraps around a straight cylinder, angled slightly off vertical.
Both are made from white borosilicate glass, which has better thermal resistance than typical glass, and are mounted on a heavy bronze base.
The name Kawari comes from the sculptural armoured helmets worn by Japanese samurai warriors, which informed the design.
Created as an edition of seven, the lamp joins a set released last year that each combine glass tubes with bronze, held together with leather straps.
"The Crane series emerged from the idea of a bronze volume and leather acting as the 'crane' lifting a glowing mass of glass," said a statement from the designer.
"As the series expands, it becomes more elemental, exploring the interaction between a grounding bronze volume and floating forms of light, most specifically in their intersections and connections."
Brittain originally trained as an architect – which she previously told Dezeen she wasn't very good at – then had a stint working for fellow lighting designer Lindsey Adelman before setting up her own studio.
Other highlights from Design Miami this year included a door carved with cartoon aquatic creatures, a bronze oatmeal bowl, and a spherical room for peace and quiet.
