This lamp is stable on the desk, teeters minimally (as in another review described), but also does not tilt when the arm is extremely far turned forward. The lamp head is nice and flat and does not interfere, even if you set very close to him face. Thanks to energy-saving LED technology, the lamp is not uncomfortably hot. The brightest is perfectly adequate for precise crafting or reading small printed books. I use the lamp sometimes even as lighting when photographing small objects. It is shown that due to the rather large LED field an almost shadowless illumination of objects is possible. Resulting in the loss of the fifth star: - Unfortunately, when you press the timer button there is no feedback (. Eg beep, brief flicker of the lamp, indicator light, etc.), so one is not quite sure whether because the sensor array has reacted, and the lamp now goes out after an hour , - Would be for reading in an armchair or in bed may also have a lateral swiveling ability of the light head helpful - but going that way.
