M-Edge e-Luminator2 Booklight for Sony Reader Touch Edition - Black
This is an excellent light. I had a mighty brite, but damaged it. I was considering the Sony cover with light, but changed my mind due to the price. The m-edge light is smaller than the mighty brite, but it does a very nice job illuminating my Sony Touch. It fits nicely in the jacket as well. I would recommend this product to anyone who is looking for a book light. It takes one AAA battery and there are two illuminations.
