Overall, the table lamp is definitely not a bad buy, but there are a few things that bother me a bit. The lamp has no power switch, so either they are left permanently on the power (standby) or is - as I - itself a switch in between. When using a power switch, however, revealed the next problem: The place is light mode and the intensity is not realized that you have to adjust all over again - even if you want to have the same light again. If you can live with the middle luminous intensity (default) and just want to turn on only the desired color mode, must always only arouse the lamp on the on / off switch on from standby and sleep until the second step can turn on the light mode. Another disadvantage of the lamp is that you can not rotate the upper arm. Otherwise, cheap and good LED lighting in all variants.
