A lamp that combines simplicity and technology to create a lucent ring of light suspended in the air. It comes in two sizes, both available in matte white or graphite, to which a shade can be affixed. Or they can be left without a shade, unapologetic. Sin broadly illuminates any work surface with direct, warm light, and does not take up space on a desk because all kinds of errant items can be kept on its base, including papers. Produced by the Barcelona-based lighting purveyor, Santa & Cole.
