Hydra - the brilliant, two-headed, LED booklight - one head for each page.
Two heads are better then one, and each of Hydra's lifetime, energy efficient, LED's will flood each page of reader's book with smooth, distortion-free, cool light.
Hydra slips into the spine of any hard or soft-cover book.
Flexible necks and heads are adjustable for maximum light coverage.

Hydra requires two AAA batteries ( not included ).
