The best thing I've ever used, I recommend it to everyone!
Finally found what I need.
I doubted whether the fixture of the lamp, its support, would be visible on the screen. No! With a fairly thin frame on the monitor - it is not visible.
Pros
An excellent lamp, now in winter you won't have to break your eyes when half of the keyboard is light from the pixar on the left, and half is in the dark.
Three gradations of color temperature and three gradations of brightness, but there is also a stepless adjustment when you hold down the middle button.
Cons
Any speck of dust is visible on the monitor screen when it is turned off, but it is))
