For a literal version of a reading light, the Lumio Book Lamp is an incredibly cool invention that opens and closes just like a real book.
As you unfold the accordion-style lamp shade, the light automatically turns off and increases its brightness the more you open it up. With a flexible spine, you can actually open up this book-shaped lamp into a 360 degree circle that stands on its side. Adjust the brightness and dim the lamp by closing it a bit, and it turns off on its own when closed shut without the use of any light switch.
The Lumio Book Lamp uses no cords, stays charged for up to 8 hours and is beautifully decorative.
