Apparently for those who like reading via ebook reader, a practical book light is very necessary such as the LED book light doubled as bookmark.
The book light is designed by Mikhail Stawsky. As shown in the images, it looks just like a common bookmark, but it’s made from a solid translucent plastic body with integrated LED lights. No doubt, in addition to marking your page in a paper book, the book light, as its name implies, can also light your book or ebook reader in the dark. Besides, the fantastic book light allows you to recharge it and set the illumination intensity via touch controls. But it’s a pity that the LED book light doubled as bookmark is still a design concept. We have no idea when it will become reality.
