Although EBook reader with eInk display offer a very paper-like presentation, the background is but usually slightly darker than printed paper. This is while reading under normal lighting conditions even more enjoyable, such displays are not quite as good as can be seen printed paper in some dim light. I often read in cafes, where the light in the evening is often not particularly optimal. By Kandle Reading Light This is no longer a problem. As the light illuminates only the reading area without radiate outward, one can also read in public places, without disturbing other people by bright light.
