The Sentry System is comprised of nine spun aluminum forms that can be mixed to create more than 80 different shapes. Designed to lock together without adhesives, the lights are easily assembled and just as importantly, disassembled and recycled. Originally created for the Massie’s Christiaan+Planck lighting brand, the design was launched at IDS 2009, where it was spotted and immediately picked up by Spanish lighting company Metalarte.
