The light of this lamp is bright and has a pleasant warm tone. Design and processing are in a good relationship with the price. Of course you will find on closer inspection minor flaws, but do not impair the function. Energy consumption: The very small power supply heats up only (not hot) when the lamp is turned on, the style remains cold. The cable to the lamp can plug in the AC adapter, which facilitates the assembly. The lamp is switched on via a rocker switch in the LED bar, better, a switch in the foot would have been. For a point deduction. I'm very satisfied overall with the gained appreciation of my desk.
