Energy-savvy consumers have been buying and using compact fluorescent light bulbs for years already, but what if there were an even more energy-efficient way to light our homes? The Liteon Eco Light concept from Tien-Ho Hsu is a revolutionary redesign of the typical rounded bulb.

Made of paper and meant to ship nearly flat, the Eco Light bulb works by coating paper with a special conductive emulsion. When electricity is applied to the emulsion, it glows as brightly as a conventional light bulb.

The Eco Light would be shipped to stores without exterior packaging. Each bulb has a hole that allows it to be hung up on shop displays. When the buyer gets it home, the bulb is assembled with a few simple twists and clicks. And when the bulbs burn out they can be tossed into the recycling bin with all of the other paper.
