After a big disappointment with LED Book Light from a department store I looked at Amazon and found, among other things, the Varta LED Book Light. It is along well rated, but has a strong competitor, which was rated as good and is slightly cheaper. The decisive factor has made the power supply. During the whole competition AAA batteries used be here "button cell" used. This makes the light very light and one can book together hold pleasant. The design is very good (in fact awarded) and very functional. The light shines very pleasant and homogeneous of all and the gooseneck is of very good quality and remains in shape. -> Buy recommendation!
