Interesting, but very expensive.

The design is created interesting and very futuristic. Also, it falls on the desk or on hardly integrates well. The operation is straightforward. There are only buttons for controlling the brightness. Unfortunately, one has to look directly into the light. The battery lasts for about 2 hours total, but making it portable and independent of a power socket. The shop works unfortunately only in the unfolded state. It is supplied with a protective case, so that the device is willing to travel. The manual is clear and can really serve you wrong the unit. The pity is that there is only one set position, because the lamp is oriented mainly for desks and other situations additional increases must be attached. Unlike other daylight bulbs you do not look at the Blue Energy directly into the light, but can shine on by indirect strong blue light the face. Especially for the winter blues or dark rooms of this device is appropriate. First, the light is used to and causes headaches. After a long, kontinurlicher treatment you can imagine that the light helps. However huge differences I could not tell. Overall, I think the price but outrageous because the Prduktionskosten, far far below the sale price and is not appropriate for a "simple" blue lamp.
