cl-2 is a minimalist lamp designed by Iowa-based designer Levi Robb. The CL-2 Lamp pushes material capabilities while achieving simplistic beauty. Thin shell concrete (1/8” thick) is hand cast to form an innovative lampshade for shaping light and illuminating space. An extensive research and experimentation process was used to arrive at a mix ratio for achieving a durable thin shell concrete that maintains functionality and aesthetic. Combining the concrete shade with a refined powder coated steel base with rubber feet allows this LED lamp to exemplify raw material richness through traditional minimalism. The quiet symmetrical form preserves the lamp’s bold material aesthetic, revealing itself in a clean, tasteful manner.
