Bao Khang Luu’s ethereal pendant lamps are both inspired by plants and made of six-pack rings hung from plastic take-out lid frames. The lamps are lit with LEDs, so they emit nearly zero heat and last a long time! The Lotus lamp is made of 40 folded six pack rings secured with crimps made from 1 soda can. The Pine cone lamp is made of 66 layered rings strung together on wires. Every two rings is separated by spacer beads made from 2 soda cans. It has a decorative cord sleeve knit from 20 plastic shopping bags.
