For the price a super LED lamp (for the Kindle, the foot is very large)

The ability to switch the brightness is very convenient.
The switch is easy to operate, the gooseneck also flexible and remains in its position.
To Verarbetung: No abnormalities after short tests.
For this price, really a clear recommendation:

I have the lamp mainly to a DMX lighting console in use.

So not in conjunction with a Kindle because I have a Kindle Paper White.

To read normal printed books I have it already and uses to which works fine.

With a slight eBook Reader, the weight of the lamp is of course more significant.
Many of the LED Clamp Lamps working with 4.5V voltage and as it is close to 3 AAA batteries to use.
The result then just a pretty big case and have their weight.
The LED lamps with 3 AAA batteries (at least for the three that I had so far) are usually built very similar and coming to a similar weight.

Weight and space saving would logically smaller and lighter button cells.

They would then quickly empty and are not going to get on every corner.
