The lamp with a power supply (10V, 500mA) operated. The power supply unit bears the INTERTEK / GS logo, which says that the power supply by authorized "independent body" has been tested for safety. Built light bar is a button at the end of the lamp is activated above. With this button you can also dim the lamp (continuously). The lamp saves a dimmed position is not, you just have to turn on the So again, if necessary dim again.
The light I find totally convincing. It is very bright at the maximum level and can also be used as a reading lamp. The light is a lot of small LEDs over a wide area ge The light color is very even "real" warm white. The light is very pleasant, so that you would like while working on has. It is by no means "cold" or bluish. I appreciate it to warm white 2800K.
The Light Arm is on a pivot and can be tilted up and down. Also, the entire upper part of the lamp, in which the LEDs sit, rotate 360 °. The light so you can align perfectly. The lamp can also be easily adjusted vertically and used as setting-wall radiator. I see on a sample picture below.
The power consumption when switched on only 5 watts. It could hardly be more economical, even yarn not given the good maximum brightness. When switched off, I get no power consumption displays. Thus, minimal, not measurable from a standard meter.
Light color, consumption, function and benefits I find very good and deserve 5 stars. Half a point deduction I give for the material appearance of the upper plastic part. This is stable, but does not work particularly dibasic. In sum, rounded 5 star.
Anyone looking for a bright LED desk lamp with a large variation range and good brightness and dimming can strike. Those looking for a designer object with high demands on the material quality, which I do not recommend this lamp.
