Processing well, no protection for the wall and without bulb

With a wall lamp with light bulb I would still expect between wall and pear a metal plate which sits the heat slightly spread so that the wall is not ankokelt. This is unfortunately not the case. The bulb floats freely against the wall. For a stone wall ok. But a wooden wall with wallpaper !? No

Plus that no pear comes here. It is in the description to read but something I have never come across. I have installed in my house about 30 lamps and no came without pear.
