Hydra Book Light — Two heads better than one

From the website:

...............................

If you've ever experienced the frustration of finally getting a book light perfectly adjusted only to have to rearrange it once you've finished the page, you'll be thrilled with the innovative twin-lamp Hydra design.

Each of the two "heads" features a bright LED bulb attached to a flexible 5"-long neck, fully illuminating both pages of an open book with cool, distortion-free light.

A 3-inch-long clip securely tucks into the spine of a hardcover or paperback, and the energy-efficient LED bulbs will last a lifetime.

Travelers, insomniacs, and nighttime readers of all stripes, this is the lightweight portable book light you've been waiting for.

Requires two AAA batteries (not included).
