Traditionally, when you wanted to read in bed you tended to use a bedside table lamp. This was fine but it made it difficult to actually get a good amount of light directed at your book, potentially lit the whole room keeping others awake and limited space on your bedside table for other thing. With Astro's range of reading lights all these issues are eliminated. Most of the Astro range are directional and can be folded in on themselves for discretion. Being angled means they can be directed on to your book as well.
