E-ink might be easier on the eyes than a backlit liquid crystal display, but it is rather tough to see in the dark. Enter the Kandle, an e-book light that is designed to minimize glare, thanks to two carefully positioned LEDs. Annoyingly, it uses CR2032 batteries, which are not rechargeable, but they are light and not too expensive if you buy them in bulk.

From the manufacturer:

The Kandle features a new patent pending design that attaches to eBooks and printed books without blocking the screen or page. The perfect accessory for any eBook, the Kandle is designed for the Amazon Kindle 1, 2, and DX, Sony Reader Digital Books, and other eBook Readers. The Kandle boasts double pivoting arms that allow for easy positioning and adjustment to tailor the screen illumination. The Main Pivoting Arm rotates 90 degrees from its closed position, and the Upper Pivoting Arm rotates another 70 degrees for complete customization. Unlike other eBook lights, the Kandle is powered by two lifetime x2 LEDs that are optimized to distribute light evenly without creating glare or eyestrain.
