lamp will not match the image!

According to the presentation (photo) there is a screw bulb large base; Or when receiving; the lights were bulbs bayonets It is true that I am not terchnicienne electricity dui and I will understand that "B22 base" was a Bayonet!; Therefore I ordered the bulb socket converter E27 to B22; But because of the change in height of the bulb increased the converter, I can not use it all in the lamp at which this system is intended; I'm disapointed!
The national approach is too complicated for me (I can not move me) it is a inutille purchase .......
