You don’t really think about a flashlight without the guts, do you? You know, the bulb, batteries, and other stuff that makes it come on at the flip of a switch. forgoes all of that by working with technology where you can print electronic circuit boards onto paper, film, and fabric by using silver particle ink. Using YUPO paper by , the same paper used for election ballots, nendo created the flashlight.
Paper-torch comprises circuits printed on both sides of the paper with a cool checkered pattern, along with two button cell batteries and seven LEDs that were glued with a conductive adhesive. Depending on how tightly you roll up the paper, the light grows dimmer or brighter due to the varying path lengths of each LED. If you want a dimmer beam, roll the paper loosely. Brighter? Roll it up tightly.
Depending on which way you roll it, with the LEDs facing outward or inward, the light turns a warm orange color or a white color.
Stick the rolled up paper through lamp base with a top ring and you have a desk lamp. The paper is super durable and water-resistant so it will hold up to lots of uses.
Clip the paper together and hang it from the ceiling for a pendant light.
