These are the Cage Group pendant lamps, and they are designed by Dare Studio. Dare Studio is newly started company that designs furniture, lighting and lifestyles products, and Cage Group is one of their products that I liked.
These lamps are made out of laser cut aluminum and is powder finished in the color you like the best. You can get them in the sizes small, medium and large, and you can also request when ordering what kind of finish you want on your lamp (witch is very cool). Obviously, these lamps are kind of industrial and have a very hard surface. The fact that the lamps have bright colors softens the whole expression, and I like it when contrasts are used in designs.
