As you've probably noticed, we love it when people find interesting new uses for old materials. This is one of the better projects in that realm. Kozo Lamps are made from original plumbing parts sourced from around the world. The materials are left raw, and the unfinished look gives Kozo Lamps an industrial quality that would fit nicely in a downtown loft. The faucet light switch, developed by Kozo, adds another neat touch.
