The Curl lamp by Sebastien Bergne looks simple at first glance, but that really isn’t the case when it comes down to its design. The originality and interaction that this lamp has to offer is something else. Being able to place the lamp in a couple of different positions is a testament to its complex design. Another nice touch on the design side of things is allowing the LED module that permits the temperature of white light to go between 2400 to 3500 degrees Kelvin, just with the rotation of the diffuser.
