Stylus Booklight Blue

This one's really popular. Stylus is stylish, functional, and compact. The sturdy clip attaches to a book's spine, not the cover, so clip it on and read the whole book without adjusting the light once. Stylus' flexible (patented) neck extends, swivels in any direction, and retracts neatly to half its total size. It shines as bright as three ordinary LEDs, with a convex lens providing a concentrated, evenly distributed light. Requires two AAA batteries (not included).
