Have a lot of difficulties with the lamp. The first went back because it was not working. The second seems to work even arbitrary (but returns went quickly). Maybe I'm too stupid for it and see a second switch, but compared to the simple Ikea lamp they will only very reluctantly. At the Ikea lamp I have also tested the Glühbrinen, where it can not lie.
Optically the lamp the figure is similar.
Whoever has the opportunity to go for Ikea and there to buy a lamp, that should do well
