The lamp has two levels of brightness. If I only need a support for the often very bad light in hotel rooms to give me a lamp ranges. Otherwise, I enjoy already the brightness of both lamps. The part can be well fixed to the book and the ebook reader. The swing arm is so long that it can illuminate the complete book. This has not given me my old lamp. It's also nice that the lamps are available in various, very attractive colors. One point deduction I admit, because the lamp light turns on when it is pressed into the trunk. Take, for transport now always get a battery. Nevertheless, I would buy this lamp again.
