Flash-Luminium is composed of American Supply’s Rainbow Flash retroreflective nylon material fused on an aluminium support. Rainbow Flash is almost black when not activated by light, but once it is activated it becomes a prismatic gradient rainbow-colour. The retro reflection is achieved through light activating micro-glass beads on the nylon surface with a gradient refractive index. Even in non-activated mode, the dark surface has a subtle rainbow tint.
Flash-Luminium typically comes in 10 meter length rolls, with a width of 120cm.
The Luminiums are a range American Supply has developed, fusing various materials on lightweight aluminium supports. This opens the materials up to new worlds of sculptural possibilities, as the aluminium holds its shape when formed, yet is soft and light enough to be manipulated by hand.
