Bring up PET / light with PET bottles

When PET bottles are collected and melted, they are recycled, but the cost and aesthetic effort of producing a bottle is already wasted. What if we can reuse a PET bottle for its aesthetic value? The mouth of a PET bottle is a screw head and the shape is the same for every bottle. With an LED light, a switch, a shade and some PET bottles, we can create a modular lighting system. You can use whatever shade and bottle of your choice to decorate interior space. This is eco-friendly in that it uses energy-effective LED light bulbs and recycled plastic shade, but it is also design-friendly in that it reuses the aesthetic value of the product.
