Lumio LED Book Lamp
Lumio LED Book Lamp can fold into a book and can light up on the go when you open “your book”. It is a cool innovative new LED light designed by Max Gunawan. The idea came from a book, when you open the cover, the light turns on; when you close it, the light goes off.
Lumio LED Book Lamp can be used at home or as a portable light source. 
The accordion-style interior is made of durable and water-resistant Tyvek. Strong magnets are installed in the covers so that the lamp can be attachable to various surfaces. 
The Lumio lamp is cordless. It provides 8 hours of continuous lighting with an internal rechargeable lithium ion battery. The long lasting LED modules can emit 500 lumen, which is slightly more intense than a 40 watt light bulb. Here is a video to show you some ways to use Lumino LED book lamp.
