Have the lamp now been just over a week in use and it is perfect for my needs.
The three lighting levels are sufficient and easily accessible via a sensor button on the luminous panel set, which is also the on-off switch at the same time. - The settings can be nothing to be desired, be rotated, tilted and swiveled. - The shape I find appealing and unobtrusive elegance.
The additional features such as detachable light panel and USB jack are nice, but not important for me.
Conclusion: A lamp that my old with fiddly 20W halogen bulbs replaced over good.
As with all LED lights, the service life and long-term performance remains to be seen.
So far, at least from my clear 5 star.
