The lamp is connected via power supply, which makes no annoying Fiep-noise. There are 2 ways to adjust the lamp. First, you can up the lamp 0-90 ° up / down move, on the other hand allows the lampshade align 0-180 °. An alignment of the lampshade to the left / right is not possible, it is only up / down.
Is operated, the lamp on the touch surface in the foot. About the middle button, the lamp is switched in 3 levels of brightness, so you can control the brightness depending on any. The light, the light color cool white, or "light work". It is well suited for reading, studying, working, etc. but those who prefer looking cozy room light, should rather resort to a lamp with the light color "warm white". In the brightest stage I feel light as a really bright and "activating".
In walking distance are 2 buttons for additional functions. There is a built-in night light function (left button), which activates a mini-LED (warm white). The right button is a time control (Auto-Off 1H). If this function is activated, which can be identified by a small red lamp, the lamp turns off after 1 hour.
The LED desk lamp has my expectations completely. It's really bright in the highest level, is chic and well-made. The additional features can I find handy. The fact that the LED also is also very economical, one has then also financed the purchase price partly on electricity cost savings compared to a halogen desk lamp.
