Very good, I like the different light modes and the dimming function.
So that I can adjust the light perfectly to my current activity.
The brightness can be adjusted over a wide range from very light to pleasantly dim.
The long arm the lamp can be aligned well.
The base plate is hard enough so that the lamp is held in position, even if the arm will extend to the front.
On the side-mounted USB port, I can load my phone. I think that's practical.
Did it mean drahlose charger for my Nokia Lumia 920 and connected it works fine.
The operation is also self-explanatory. Even if the labels are in English, even someone with no knowledge of English should be good to deal with it, because the icons are sufficiently meaningful.
Only you choose the desired light mode, then the luminosity is set with the +/- keys.
There is also a function for automatic shutdown after 60 minutes. The button is located to the left of the power button. If the automatic shutdown is activated, the power LED flashes at regular intervals.
Over the lifetime of the LEDs can be at this time say little. However, I assume that at this price-quality LEDs were installed, which should last longer than 10 years of rule.
So far everything is working very well and I am with this lamp more than satisfied.
The delivery was very quick. The packaging was perfect.
A little tip:
On the control panel, a protective film is applied, which should be removed before use.
When it leaves this film, the buttons do not react or only delayed policy.
