Concrete never really rivets me in sidewalk or flight of stairs form--unless I'm falling on and picking hunks of it out of my face I guess--but put it in a watch or on a lamp shade and I'm all, Duuuuude. This concrete pendant light has a shell made of leosteen, a tough material commonly used in industrial flooring. At least in Leipzig, Germany, which is where the hanging gray beauts are designed and crafted.
Though sturdy and formidable in appearance, the light's (this one is named Catherina 30) creator notes that leosteen is about a third lighter and more flexible than standard concrete mixtures. It is also waterproof. The wrinkled, textured light depicted here measures 11" in diameter 4" tall, and weighs 3.3 pounds.
