The 'Arco' floor lamp was first designed by Achille and Pier Giacomo Castiglioni in 1962. Such is its iconic status and sucess that it is still in production today.
Speaking of iconic designers, someone who is making their mark in today's lighting design world is Benjamin Hubert. I've posted about him before in a post on unusual uses for concrete in design. His Heavy Lights (below) are one such use.
Another notch in his ever expanding belt is his Labware lights
His work has the same simplistic elegance that attracts me to the designs of Naoto Fukasawa whose 'Wan' Light (below) offers the same sculptural element to its surroundings as Huberts work does.
The light sits like a bowl on a shelf or flat surface. That is unless you want to tilt the angle of the light, then you simply shift its weight which is made up of the sand particles inside its walls.
