MyLight today launched the MarkLight, a portable light designed to fit in unconventional locations. Originally intended for books, the MarkLight centers around a thin, malleable strip that can be slipped in between pages to be used as a bookmark as well as a reading light. Because of the even illumination provided by its three LED lamps, the MarkLight can also be used to light the keys of a laptop's keyboard or act as a small stand-alone lamp, according to MyLight. The device lasts for up to 40 hours on two AAA batteries and comes with several different skins, including real and simulated leather, nylon, or plush cloth. Versions dressed in real leather ship today for $20; lights with the remaining covering options will be available soon for $15.
